2 Overview

This document provides information about the correct application of both heat and smoke detectors/sensors in conjunction with fire
alarm systems.

The information in this publication is intended to be used as a technical guide only. Ensure that the requirements of applicable codes and
standards, as well as the directives of Authorities Having Jurisdiction (AHJs) are followed.

2.1 Special considerations

Before installing detectors or sensors, make a survey of the area to be covered in accordance with the information provided in NFPA 72, an
excerpt of this is provided in

Proper Use of System Smoke Detectors.

2.1.1 Special considerations for smoke detectors and sensors

Consider the following before installing detectors or sensors:

• Is there human occupancy?

• The contents to be protected.

• The type of construction and use.

• The burning characteristics of contents.

• The air movement - stratification.

• The deflections and obstructions.

• The height of ceilings.

• The surface conditions of ceilings.

• The type of ceiling construction.

• The total area.

• The vent locations: velocities and dilution.

Smoke detector and sensor applications. For additional information, refer to NFPA 72 and the NEMA Guide for

2.1.2 Smoke detector and sensor applications

Each detector/sensor can provide up to 900 square feet, or 84 square meters of coverage, depending on the following:

• The requirements of local codes.

• The results of engineering evaluation.

2.2 Where to place detectors and sensors

2.2.1 Correct locations for detectors and sensors

Important: The guidelines in this section are adapted from standards published by the National Fire Protection Association, Quincy,
Massachusetts, U.S.A. These standards include NFPA 72, “National Fire Alarm and Signaling Code”; NFPA 70, “National Electrical Code”, Article
760; and NFPA 90A, “Standard for the Installation of Air Conditioning and Ventilating Systems.”

To provide effective early warning of a developing fire situation, install smoke detectors or sensors in all areas of the protected premises.
Total coverage as defined by NFPA 72 includes all rooms, halls, storage areas, basements, attics, lofts, and spaces above suspended
ceilings including plenum areas utilized as part of the HVAC system. In addition, this includes all closets, elevator shafts, enclosed stairways,
dumbwaiter shafts, chutes, and other subdivisions and accessible spaces.

Fire detection systems installed to meet local codes or ordinances may not be adequate for early warning of the fire. Some codes or
ordinances have minimum objectives, such as capturing elevators, or preventing circulation of smoke through HVAC systems instead of
early detection of fire.

Weigh the costs against the benefits of installing a complete fire detection system when any detection system is being installed. The
location, quantity, and zoning of detectors or sensors is determined by the objectives of the installation, rather than the minimum
requirements of any local codes or ordinances.

Detectors or sensors can be omitted from combustible blind spaces when any of the following conditions prevail:

• Where the ceiling is attached directly to the underside of the supporting beams of a combustible roof or floor deck.

• Where the concealed space is entirely filled with noncombustible insulation. In solid joist construction, the insulation need only fill the
space from the ceiling to the bottom edge of the joist of the roof or floor deck.

page 4 574-709 Rev. AP

4098 Detectors, Sensors, and Bases Application Manual

• Where there are small concealed spaces over rooms, provided the space does not exceed 50 square feet, or 4.6 square meters.

• In spaces formed by sets of facing studs or solid joists in walls, floors, or ceilings where the distance between the facing studs or solid
joists does not exceed 6 inches, or 15 centimeters.

page 5 574-709 Rev. AP

4098 Detectors, Sensors, and Bases Application Manual

Detectors or sensors can also be omitted from below open grid ceilings where all of the following conditions are met:

• The openings of the grid are at least 1/4 inch, or 6 millimeters in the smallest dimension.

• The thickness of the material does not exceed the smallest of the grid openings.

• The openings constitute at least 70% of the area of the ceiling material.

Detectors or sensors are usually required or recommended underneath open loading docks or platforms and their covers, and in
accessible under-floor areas in buildings without basements. Detectors or sensors may be omitted from combustible blind spaces when all
of the following conditions prevail:

1. The space is not accessible for storage purposes, it is protected against the entrance of unauthorized persons, and it is protected

against the accumulation of windblown debris.

2. The space contains no equipment or structures, such as steam pipes, electrical wiring, ducts, shafts, or conveyors that could

potentially ignite or conduct the spread of fire.

3. The floor over the space is tight.

4. Non flammable liquids are processed, handled, or stored on the floor above the space.

“Total coverage” as described in NFPA 72, is the definition of a complete fire detection system. In some of the specified areas of coverage,
such as attics, closets, under open loading docks or platforms, a heat detector may be more appropriate than a smoke detector. Give
careful consideration to the detector manufacturer’s instructions and the following recommendations in this guide.

When only one detector/sensor is required in a room or space, install the detector or sensor as close to the center of the ceiling as
possible. Central location of the detector or sensor is best for sensing smoke or fire in any part of the room. If a center location is not
possible, place it no closer than 4 inches, or 10 centimeters from the wall, or if it is listed for wall mounting, it can be mounted on the wall.
Wall mounted detectors or sensor should be located approximately 4 to 12 inches, or 10 to 30 centimeters from the ceiling to the top of
the detector, and at least 4inches, or 10 centimeters from any corner wall junction, see Figure 1.

Figure 1: Wall and ceiling mounted detector or sensor

When an air supply or an air return duct opening is present in a room or space, install the detectors or sensors in the path of the air flow
toward the return air duct opening, see Figure 2.

page 6 574-709 Rev. AP

4098 Detectors, Sensors, and Bases Application Manual

Figure 2: Detector placement - air supply or return ducts

Smoke tests help determine the correct placement of detectors and sensors. Observe the smoke travel directions and velocity, as these
factors can affect detector and sensor performance.

Placement of a detector or sensor near air conditioning or incoming air vents can cause excessive accumulations of dust and dirt on
the detector or sensor. This dirt can cause the detector or sensor to malfunction and cause nuisance alarms. Do not locate detectors or
sensors closer than 3 feet, or 0.9 meters from an air supply diffuser.

Spot type detectors or sensors in correctly engineered systems, can also be installed in return air ducts, or in approved duct detector
housings designed for this application. Although duct detectors are not a substitute for open area detectors, they can provide an effective
method of initiating building control functions to prevent smoke being transported from the fire area to other parts of a building.

2.3 Where not to place detectors and sensors

2.3.1 Incorrect locations for detectors and sensors

Installing detectors or sensors in an incorrect location is a major cause of nuisance alarms. To avoid nuisance alarms do not install
detectors or sensors in environments that can cause them to malfunction. See the following table and examples:

Table 1: Environmental conditions that influence detector response*

Beam O O X X O
Air Sampling O O X X O
*See Table A-5-3.6.1.1 in NFPA 72
X = May affect detector or sensor responses
O = Generally does not affect detector or sensor responses

Do not install detectors or sensors in the following areas:

• In excessively dusty or dirty areas, such as feed rooms, steel mills, etc. Dust and dirt can accumulate on the detector or sensor’s
sensing chamber and make it overly sensitive, or block the air entrances to the sensing chamber and make the detector or sensor less
sensitive to smoke. Be especially careful to avoid areas where fumigants, fog or mist-producing materials, or sweeping and cleaning
compounds are used. These substances can cause nuisance alarms.

• Outdoors, in stables, open storage sheds, or other open structures affected by dust, air currents, or excessive humidity and
temperature.

• In damp or excessively humid areas, or next to bathrooms with showers. Water droplets can accumulate inside the sensing chamber
and make the detector or sensor overly sensitive. A large amount of humid air is produced during a hot shower. The moisture in this
humid air can enter the sensing chamber as water vapor, then cool and condense into droplets causing a nuisance alarm.

• In elevator lobbies over ashtrays or where people smoke while waiting for the elevator.

• In very cold or very hot environments, or in unheated buildings or rooms where the temperature can fall below or exceed the
operating temperature range of the detector or sensor. At temperatures below 32°F, or 0°C, ice crystals or condensation can appear
inside the sensing chamber and make it overly sensitive or cause a nuisance alarm. At temperatures above the operating range of the
detector or sensor greater than 120°F, or 49°C, its internal components may not function correctly.

• In or near areas where combustion particles are normally present, such as in kitchens or other areas with ovens and burners; in
garages, where particles of combustion are present in vehicle exhausts; within 15 feet, or 4.5 meters of any type of furnace, hot water
heater, or gas space heater; or in welding shops or other types of work areas where some form of combustion is used in the activity

normally conducted in that area. When a detector must be located in, or adjacent to such an area, a fixed temperature heat detector
can be appropriate.

• In air streams passing by or through kitchens. Air often enters a residence or a residential unit of an apartment building through
cracks around the front or back doors. If the air return is in the bedroom hallway or in the bathroom, and if air from the kitchen easily
enters the air stream going from the door to the air return, combustion particles from cooking can cause nuisance alarms. Install
detectors or sensors so that they protect the bedrooms but are out of the air stream.

• In or near manufacturing areas, battery rooms, or other areas where substantial quantities of vapors, gases or fumes may be present.
Strong vapors, like excessive humidity, can make detectors or sensors overly sensitive or less sensitive than normal. In very large
concentrations, gases heavier than air, such as carbon dioxide, may make detectors or sensors more sensitive, while gases lighter
than air, such as helium, may make them less sensitive. Aerosol particles may collect on detector or sensor chamber surfaces and
cause nuisance alarms.

• In insect-infested areas. If insects enter a detector or sensor’s sensing chamber, they can cause a nuisance alarm. Perform insect
eradication procedures before installing detectors or sensors in these locations. If spraying is part of this process, do not allow insect
spray to enter the detectors or sensors.

• Near fluorescent light fixtures. Electrical noise generated by fluorescent light fixtures may cause nuisance alarms. Install detectors or
sensors at least 1 foot, or 0.3 meters away from these light fixtures.

• When using the CO Base for CO fire detection, do not install in locations that can have potentially high non-fire levels of CO.

Underwriters Laboratories (UL) has three standards for smoke detectors:

• One for duct detectors or sensors, UL 268A.

• One for single and multiple station detectors/sensors, UL 217.

• One for system type detectors or sensors, UL 268.

Only use detectors or sensors in the applications for which they are specifically listed.

The NFPA 101 Life Safety Code states that single station smoke detectors shall sound an alarm only within an individual living unit or similar
area and shall not actuate the building fire alarm system. It also states, “All systems and components shall be approved for the purpose for
which they are installed.”

In addition to possible code noncompliance, the following deficiencies exist in a series of residential smoke detectors connected in a fire
alarm system mode:

• Because the fire alarm system is not supervised, vandals or others can disconnect a detector or the entire system, leaving a building
without protection. In this situation the residents are unaware of the serious life threatening condition.

• Residential detectors do not latch in alarm, the detector self-resets. One detector in alarm sounds all the detectors that are
connected together. In this situation, after the alarm condition is cleared, it is difficult to identify or locate a specific detector that
initially put the system into alarm,.

System detectors or sensors latch in alarm. They do not reset until the power is momentarily disconnected. This makes it easier to identify
the location of the detector or sensor that caused the control panel to alarm. In addition, system detectors are specifically designed to
connect to a supervised control panel. Two-wire detectors require a UL compatibility review to verify that the detector and panel operate
correctly together.

A typical life safety fire alarm system for an apartment complex uses system detectors or sensors and manual fire alarm stations in the
hallways and common areas of the complex, and residential single station type detectors and heat detectors in the individual apartments.
The system detectors or sensors, manual stations and heat detectors are connected to a supervised control panel, sound a general
alarm, and automatically notify the proper authorities that a fire condition exists. The residential detectors located in the apartments are
interconnected only within the individual living quarters of each apartment. These residential units sound an alarm only in the apartment
unit.

2.4 Principles of operation

2.4.1 Introduction

This section describes how the different types of detectors and sensors work. For additional information about TrueAlarm sensor
operation, refer to the TrueAlarm Concepts publication (PER-91-024).

2.4.2 Heat detector operation

The heat detector senses the heat or the Rate-of-Rise (ROR) in the air temperature of the environment in which it is located. The heat
detector is comprised of electronic circuitry and a mechanical package that is designed to sense the ROR of the air temperature in an
expedient and reliable fashion. Upon detection of an abnormal increase in air temperature, or ROR in air temperature, the electronics
indicate an alarm by increasing the amount of current draw from the monitor zone it is connected to. The monitor zone is a supervised

page 8 574-709 Rev. AP

4098 Detectors, Sensors, and Bases Application Manual

detection circuit that is connected to a main control panel that takes appropriate action to indicate an alarm has been reported, if the zone
current is substantially increased.

Heat detectors are an electronic design, the temperature of the air is sensed using two negative temperature coefficient thermistors. The
resistance of the thermistors goes down with an increase in temperature. One thermistor is placed in a position that senses the open
air temperature very rapidly (RT1). The second thermistor is positioned in a small cavity that protrudes out from the main body of the
detector (RT2). The location of RT2 detects a quick change in the air temperature, but for a slow or medium rate of temperature change,
the detector does not signal an alarm due to the ROR feature. For a slower change in temperature, the detector signals an alarm due to a
set fixed temperature that is sensed by RT1. For a fast temperature rise, when a difference in temperature is sensed by RT1 and RT2 has
reached a predetermined amount, the detector signals an alarm.

2.4.3 Photoelectric smoke detectors or sensors

These devices operate on a light scattering principle. The smoke sensing chamber contains an infrared LED source with a peak spectral
emission of 880 nanometers. This source is placed at an angle from a spectrally matched photo-diode receiver. During a NO SMOKE
condition, only light reflected from the chamber walls enters the receiver and shows up as a small photo-current. As smoke particles enter
the sensing chamber and cross the light beam of the LED, more light reaches the receiver due to scattering. The receiver circuitry converts
this photo-current into a signal voltage. In a detector, when this voltage reaches a preset level, an alarm is signaled. In a sensor, this signal
voltage goes into an 8-bit, analog to digital (A to D) converter. A digital representation of this signal voltage is then transmitted to the fire
alarm panel for further processing.

2.4.4 Carbon monoxide gas detectors or sensors

The CO Sensor and Sounder Bases with a CO Replacement Cartridge (CORC) modules work in conjunction with existing detector heads.
The CO Sensor Base enhances fire detection and combines fire and toxic gas leakage detection in a single device. The CO sensor measures
the concentration of carbon monoxide gas in the air in part per million (PPM). When toxic gas operation is selected, the FACP panel can
generate either a supervisory, utility, or priority 2 alarm. The alarm level is calculated within the panel based on the time integrated CO
levels that are measured at the detector.

3 4098 Smoke Detectors, Heat Detectors and Bases

This chapter contains specification and mounting information for 4098 Smoke Detectors, 4098 Heat Detectors, and 4098 Bases.

3.1 4098 Smoke Detectors

CAUTION: Install the detectors described in this publication in accordance with applicable NFPA standards, local codes, and the
Authorities Having Jurisdiction (AHJs). Failure to follow these instructions may result in failure of the detector to initiate an alarm condition.
The manufacturer is not responsible for detectors that have been improperly installed, tested, or maintained.

3.1.1 Smoke detector limitations

The smoke detectors used with these bases are designed to activate and initiate emergency action, but do so only when used in
conjunction with other equipment. They are designed for installation in accordance with NFPA 72 National Fire Alarm and Signaling Code.

• Smoke detectors do not work without power. AC or DC powered smoke detectors do not work if the power supply is cut off for any
reason.

• Smoke detectors do not sense fires when smoke does not reach the detectors. Smoke from fires in chimneys, in walls, on roofs or on
the other side of closed doors may not reach the smoke detector and alarm it.

• A detector may not detect a fire developing on another level of a building. For this reason, locate detectors on every level of a building.

• Smoke detectors have sensing limitations. In general, detectors do not provide warning for fires resulting from inadequate fire
protection practices, violent explosions, escaping gases, incorrect storage of flammable liquids such as cleaning solvents, other safety
hazards, or arson.

• Smoke detectors do not last forever. Smoke detectors contain electronic parts. Even though detectors are made to last for many
years, any of these parts can fail at any time. Therefore, test smoke detector systems according to NFPA 72 at least annually. Clean
and maintain smoke detectors regularly. See the

Compatibility and testing section of this publication for the cleaning instructions.

3.1.3 Mounting requirements

All smoke detectors identified in Table 2 mount to a detector base, refer to
considerations when mounting smoke detectors.

Important: Smoke must enter the chamber of the detector. Air flow, air stratification, air velocity, air stagnation, and air migration affects
detector efficiency.

Note: Where the possibility of positive airflow from the electrical conduit or junction box exists, use 3M Weatherban number 606, or an
equivalent, non-flammable sealing compound to seal the conduit openings.

• Do not install detectors in areas where temperatures are likely to exceed 100°F or 38°C or fall below 32°F, or 0°C.

• Because the 4098-9602 detector combines heat sensing, DO NOT install this detector in locations where the ambient temperatures
exceed 100°F, or 38°C or where temperature fluctuations above 6°F per minute occur.

• Do not install detectors on a ceiling within 4 inches, or 10 centimeters of a wall.

• Do not install detectors where forced air ventilation can dilute the smoke before it reaches the detector.

• Do not install detectors in areas where smoke is normally present, such as kitchens, furnace rooms, laundry rooms, loading docks,
rooms with fireplaces, rooms with candles, soldering rooms, and so on.

4098 Bases for more information. Use the following

page 10 574-709 Rev. AP

4098 Detectors, Sensors, and Bases Application Manual

• Do not install detectors in areas where there is likely to be steam, such as in hospital patient rooms with vaporizers, near shower
rooms, above large sinks, and so on.

• Do not install detectors above ashtrays in elevator lobbies.

• Wall-mounted detectors should be located 4 to 12 inches, or 10 to 30.5 centimeters from the ceiling to the detector head.

• Protect all detector heads during construction to avoid infiltration of construction debris. Remove any protective covers before
activating the system.

• If using an adapter plate, tighten the mounting screws without warping the adapter plate.

• Smoke detectors are not to be used with detector guards unless the combination has been evaluated and found suitable for that
purpose.

3.2 4098 Heat Detectors

This section contains general notes, specifications, and mounting information about the heat detectors in

WARNING: Heat detectors are NOT life-safety devices: USE HEAT DETECTORS FOR PROPERTY PROTECTION ONLY! For life-safety
requirements, use smoke detectors.

Note:

• For all heat detectors, provide electronic supervision with a battery back-up at the fire alarm control panel.

• Where the possibility of positive airflow from the electrical conduit or junction box exists, use 3M Weatherban number 606, or an
equivalent, non-flammable sealing compound to seal the conduit openings.

• Refer to NFPA 72 for application, test and maintenance requirements.

3.2.1 Heat detector types

Fixed temperature heat detectors

Electronic fixed temperature heat detectors use a fast response, thermistor based design that senses temperatures quickly and accurately,
and consistently identifies when fixed temperatures are exceeded. For this reason, the fixed temperature detectors are recommended for
most applications. With a UL spacing distance of 60 X 60 foot, the fixed temperature electronic heat detectors replace both the mechanical
fixed and the mechanical ROR heat detectors.

ROR temperature heat detectors

Electronic ROR heat detectors detect fixed temperature alarm thresholds in the same way as the fixed temperature heat detectors, and
also detect a ROR alarm with a patented ROR detection design that quickly responds to sudden temperature variations. Due to the nature
of the fast response to temperature changes, the correct installation of ROR heat detectors is important. Install ROR heat detectors in
stable environmentally controlled areas. Do not install these detectors where hot or cold air can be blown on them, such as near ductwork,
industrial equipment, air vents, and so on. Do not install ROR detectors where more than 6ºF per minute temperature changes can
normally occur.

4.3.1 Special applications

1. The sensitivity range, or setting for the 4098-9714, 4098-9774 and 4098-9764 sensor is 0.2%/FT to 3.7%/FT smoke obscuration.

The sensitivity settings for special applications are configured in the programmer. Sensitivity settings higher than 1.0%/FT are not
UL compliant.

2. Special application sensitivities are not for general use and may be more prone to false alarms if used in unsuitable

environments. Potental nuisance sources include steam and particles generated from cooking. Sensors set to a special
application sensitivity are not suitable for use in areas where cooking appliances may be used. If cooking appliances are used
within the protected space, a normal application mode or configuration must be used for that area. Suitable environments for
special application sensitivity settings include data centers, telecommunications, and clean rooms. Unsuitable environments
include kitchens and living areas.

3. The 0.2%/FT, 0.5%/FT and 1.0%/FT settings are very sensitive settings: only use the 0.2%/FT setting when a sensor is located

in a totally smoke-free and controlled temperature environment, such as a computer room or telephone switching
exchange.

4. To determine if an area is suitable for the 0.2%/FT setting, complete the following steps:

a. Set the sensitivity for the installed sensor at 1.5%/FT.
b. Monitor the peak values for 90 days. If you record a peak value of 0.1%/FT or higher during the 90 days, do not use the 0.2%/

FT setting.

5. To determine if an area is suitable for the 0.2%/FT setting, complete the following steps:

a. Set the sensitivity for the installed sensor at 1.5%/FT.
b. Monitor the peak values for 90 days. If you record a peak value of 0.25%/FT or higher during the 90 days, do not use the 0.5%/

FT setting.

6. To determine if an area is suitable for the 1.0%/FT setting, complete the following steps:

a. Set the sensitivity for the installed sensor at 1.5%/FT.
b. Monitor the peak values for 90 days. If you record a peak value of 0.5%/FT or higher during the 90 days, do not use the 1.0%/FT

setting.

Note: The 4098-9771, 4098-9772, 4098-9773 and 4098-9794 Sounder Bases have a 9-position DIP Switch. The first eight DIP Switches set
the sounder base address. DIP Switch Position 9 is set to OFF or ON depending on the sounder base power source. When the sounder
base is connected to a 24 VDC power source, DIP Switch Position 9 is set to “OFF” and the 24 VDC power is supervised by the sounder
base. When the sounder base is powered by the panel’s Notification Appliance Circuit (NAC), DIP Switch Position 9 is set to “ON” and
the power is supervised by the NAC and not the sounder base. The 4098-9770 base has the same layout, but it does not have sounder
functionality. It uses an 8-way DIP switch only.

6.3 Maintenance and testing

6.3.1 Maintenance

The minimal requirement for detector and sensor maintenance requires clearing of surface dust using a vacuum cleaner. Ensure that the
cleaning programs comply with the NFPA and local environments. Ensure that cleaning of the internal chamber is only done by a qualified
technical representative.

For service, return to your local branch office.

6.3.2 Testing

Smoke sensor sensitivities are set and continuously monitored by the control unit. Dirty or out-of-range sensors are annunciated by the
control unit. This functionality complies with NFPA 72.

page 35 574-709 Rev. AP

4098 Detectors, Sensors, and Bases Application Manual

Note: When testing detectors or sensors, refer to NFPA 72, or contact your local branch office.

CAUTION: Before functionally testing the detectors or sensors, be sure to disconnect the city connection, releasing devices, and

extinguishing systems. For the 4120, 4006, 4008, 4020, 4010, 4100+, 4100U, 4100ES, 4010ES, or 4007ES panel, put the panel in the Walk
Test mode.

6.3.3 Preferred method of testing smoke detectors or sensors

NFPA minimally requires annual functional testing of smoke detectors or sensors at their installed location. To perform this annual test, use
the Solo 336 Aerosol Smoke Dispenser.

Important: After testing detectors, reset the fire alarm panel to restore the fire alarm system to a normal status. After testing sensors,
ensure you clear the peak values.

6.3.5 Alternate method for testing sensors

The following test method is suitable for functional checks of sensor bases during installation, however, testing with smoke must be
performed to comply with NFPA requirements.

For all sensor bases, position the 553-810 Magnet Tester ½ inch to ¾ inch, or 12 millimeters to 20 millimeters counterclockwise from the
visible LED on the sensor base, see Figure 24.

For MAPNET II devices, testing a sensor using a magnet reports a value of 255 for actual/peak. This does not occur for IDNet devices. Clear
the peak value after testing.

6.3.6 Magnetic Test for photoelectric detectors

Test the 4098 Photoelectric Detectors by placing a magnet above the location indicated by a “|” mark embossed on the cover for 4
seconds. Use the Magnetic Tester, Part No. 553-810, Table 14, and the following information to test the detectors.

Table 14 describes the LED reaction during Normal and MAG TEST modes to the Normal, More Sensitive, Less Sensitive, and Non­Functional states of the detector.

When placing the magnet at the location indicated by a “|” mark embossed on the cover, the visible LED flashes indicating the condition of
the detector.

The following are descriptions of the detector when it is in MAG TEST:

• NORMAL - When in MAG TEST, the detector latches into alarm if the detector is within calibration range and the visible LED stays ON.

• MORE SENSITIVE - When in MAG TEST, if the detector is more sensitive than the maximum calibration, the visible LED quickly flashes,
twice a second. Following the sixth flash, the detector latches into alarm and the visible LED stays ON.

• LESS SENSITIVE - When in MAG TEST, if the detector is less sensitive than the minimum calibration, the visible LED slowly flashes four
times, once every two seconds. Following the fourth flash, the detector latches into alarm and the visible LED stays ON.

• NON-FUNCTIONAL DETECTOR - If the detector is less sensitive than the minimum permitted sensitivity, or if there is a fault in the
temperature sensing circuit (4098-9602), the visible LED does not flash normally. When in MAG TEST, the visible LED slowly flashes
four times, once every two seconds. After the fourth flash, the detector does NOT latch into alarm, the LED stops flashing and turns
OFF.

If the detector is outside the normal operating range, clean it. If after cleaning the detector still indicates an abnormal sensitivity, replace
the detector.

6.3.7 Maintenance of the CO Sensor

The CO Sensor is not as susceptible to dirt as the photo or ion sensors, and does not compensate for a loss of sensitivity over the period
of its lifetime.

The following two operations to inform a qualified or trained service person that a CO sensor has reached its end of life:

• The FACP panel generates an End of Life trouble notifying the user that a replacement sensor is required.

• Manual standard maintenance testing by a qualified or trained service person checks that the device is fully operational.

6.3.8 End of life service

The end of life of a CO Sensor is based on the manufacture date of the device, not the installation date.The FACP panel daily checks each
IDNet CO combination sensor for the End of Life trouble expiration date.The FACP panel generates the following status report based on
the condition of the CO Sensor:

• None: the CO Sensor has not reached the expiration date.

• Almost Expired 6M: the CO Sensor is within 6 months of the expiration date.

• Almost Expired 12M: the CO Sensor is within 12 months of the expiration date.

• Expired (End of Life): the CO Sensor’s date has expired.

To clear the trouble at the panel:

1. Install a new CRS with a valid date.

2. Perform a hardware reset of the FACP.

Note: For the panel to annunciate these warnings, enable the logging of the Almost Expired trouble, with the exception being the
Expired trouble condition which does not require any activation.

The TrueAlarm CO report can also be used to list all End of Life dates of CO sensors in the panel. The report is a quick and easy way to
check if any sensors will expire before the next visit to the site.

6.3.9 Standard maintenance

To verify that the sensors are operating correctly, standard maintenance of the CO sensors is required. The standard maintenance process
is as follows:

1. The FACP panel is put into the service test mode using either the diagnostic function menu item on the front panel or the system

diagnostic computer port command.

2. A trouble displays at the panel indicating that the panel is in the Device Test Mode.

3. A tester introduces CO gas, heat and smoke simultaneously into the detector.

4. The device LED on the base turns ON steady if any, but not all of the sensors on the device cross an alarm threshold.

5. The device LED on the base flashes slowly if all of the sensors cross an alarm threshold.

6. The appropriate action based on the point type of the CO sensor is taken at the panel.

7. Device Test Mode shall is entered if a faster response time is needed during Walktest.

Note: There is a 20 device LED maximum that can be ON/Flashed at any given time. This limit applies during testing, and during alarm
operation. Reset the panel before this limit is reached during testing so that the LED can be used as an indication of a successful test.

Figure 26: Testing a single CO sensor

Figure 27: Simultaneous testing
of multiple sensor technologies

Note: The LED on the base can turn ON prior to slow flashing
depending on when the individual sensors alarm. Only the last
LED requested to flash will slow flash. All others will turn to steady
ON. Flashing of the LED will only be performed when the IDNet CO
algorithms are disabled for testing. During Walktest, a reset timer
is activated so that the LED is reset to the OFF state without need­ing a reset at the panel. This reset is user programmable and can
be as short as 15 seconds long. This automatic reset may cause
the LED on the base to turn OFF before the test is complete. For
example, it's possible that depending on the test tool, the LED (if
all of the sensors are good) could turn ON then reset to OFF, turn
ON then reset to OFF then finally slow flash then reset to OFF.

Note:

The following describes the LED states:

LED OFF - No sensors have exceeded their thresholds

LED ON - At least one sensor exceeded its threshold

LED FLASHING - All sensors for this device have exceeded their
thresholds (Note: This could be 2 or 3 sensors depending on what
type of CO combination device is configured)

Flashing will only be performed when in testing (IDNet CO
algorithms are disabled).

6.3.11 Cleaning

Introduction

If the sensitivity of the device does not match what is marked on the device’s label, clean the device using a source of oil-free, filtered,
compressed air such as Dust-Off, or Tech Duster, and so on.

CAUTION: Notify the appropriate building personnel prior to removing any detectors or sensors from service.

6.3.11.1 Photoelectric smoke detector or sensor cleaning

Blow the compressed air through the open vents around the device so that air enters and cleans the black chamber cover and insect
screen assembly, Part No. 677-224, located under the white protective cover.

If the sensitivity of the device does not match what is marked on the device’s label after cleaning, replace the device.

6.3.12 Trouble indications

6.3.12.1 Trouble indications for TrueAlarm sensors

The TrueAlarm smoke sensor is a measuring device that sends data regarding smoke density to the 2120, 4008, 4010, 4020, 4100, 4100+,
4100U, 4100ES, 4010ES, and 4007ES FACPs. The TrueAlarm heat sensor operation is similar, but sends temperature data instead of smoke
density data. The FACP uses this data to determine whether a trouble has occurred.

The TrueAlarm sensor has two automatic trouble indications:

• Dirty

• Excessively Dirty

A “Smoke Sensor Dirty” trouble condition is reported when the average value on an individual sensor reaches a set threshold value. At this
time, the FACP is still compensating for environmental factors and is holding the set sensitivity level.

A “Smoke Sensor is Excessively Dirty” trouble condition is reported when the average value of an individual sensor reaches a slightly higher
set threshold level. At this point, the FACP no longer compensates for environmental factors, and the sensitivity level drifts. Although an
“Excessively Dirty” trouble is reported, the sensor continues to operate and reports an alarm condition when one is detected.

In addition to the two automatic trouble conditions, the FACPs have digital pseudo points that must be turned ON so that a TrueAlarm
sensor that is close to being a dirty sensor reports as if it is “almost dirty”. This is useful when scheduling maintenance for dirty sensors, it
provides a means of checking if other sensors are approaching a dirty state.

The following table shows appropriate action to take when certain trouble indications occur:
