Fire Alarm System Limitations

While a fire alarm system may lower insurance rates, it is not a substitute for fire insurance!

An automatic fire alarm system–typically made up of smoke detectors, heat detectors, manual pull stations, audible warning devices, and a fire alarm control with remote notification capability–can provide early warning of a developing fire. Such a system, however, does not assure protection against property damage or loss of life resulting from a fire.

The Manufacturer recommends that smoke and/or heat detectors be located throughout a protected premise following the recommendations of the current edition of the National Fire Protection Association Standard 72 (NFPA 72), manufacturer's recommendations, State and local codes, and the recommendations contained in the Guide for Proper Use of System Smoke Detectors, which is made available at no charge to all installing dealers. A study by the Federal Emergency Management Agency (an agency of the United States government) indicated that smoke detectors may not go off in as many as 35% of all fires. While fire alarm systems are designed to provide early warning against fire, they do not guarantee warning or protection against fire. A fire alarm system may not provide timely or adequate warning, or simply may not function, for a variety of reasons:

Smoke detectors may not sense fire where smoke cannot reach the detectors such as in chimneys, in or behind walls, on roofs, or on the other side of closed doors. Smoke detectors also may not sense a fire on another level or floor of a building. A second-floor detector, for example, may not sense a first-floor or basement fire.

Particles of combustion or "smoke" from a developing fire may not reach the sensing chambers of smoke detectors because:

• Barriers such as closed or partially closed doors, walls, or chimneys may inhibit particle or smoke flow.

• Smoke particles may become "cold," stratify, and not reach the ceiling or upper walls where detectors are located.

• Smoke particles may be blown away from detectors by air outlets.

• Smoke detectors may be drawn into air returns before reaching the detector.

The amount of "smoke" present may be insufficient to alarm smoke detectors. Smoke detectors are designed to alarm at various levels of smoke density. If such density levels are not created by a developing fire at the location of detectors, the detectors will not go into alarm.

Smoke detectors, even when working properly, have sensing limitations. Detectors that have photoelectronic sensing chambers tend to detect smoldering fires better than flaming fires, which have little visible smoke. Detectors that have ionizing-type sensing chambers tend to detect fast-flaming fires better than smoldering fires. Because fires develop in different ways and are often unpredictable in their growth, neither type of detector is necessarily best and a given type of detector may not provide adequate warning of a fire.

Smoke detectors cannot be expected to provide adequate warning of fires caused by arson, children playing with matches (especially in bedrooms), smoking in bed, and violent explosions (caused by escaping gas, improper storage of flammable materials, etc.).

Heat detectors do not sense particles of combustion and alarm only when heat on their sensors increases at a predetermined rate or reaches a predetermined level. Rate-of-rise heat detectors may be subject to reduced sensitivity over time. For this reason, the rate-of-rise feature of each detector should be tested at least once per year by a qualified fire protection specialist.

Heat detectors are designed to protect

property, not life.

IMPORTANT!

Smoke detectors must be installed in the

same room as the control panel and in rooms used by the system for the connection of alarm transmission wiring, communications, signaling, and/or power.

cated, a developing fire may damage the alarm system, crippling its ability to report a fire.

Audible warning devices such as bells may not alert people if these devices are located on the other side of closed or partly open doors or are located on another floor of a building. Any warning device may fail to alert people with a disability or those who have recently consumed drugs, alcohol or medication. Please note that:

• Strobes can, under certain circumstances, cause seizures in people with conditions such as epilepsy.

• Studies have shown that certain people, even when they hear a fire alarm signal, do not respond or comprehend the meaning of the signal. It is the property owner's responsibility to conduct fire drills and other training exercise to make people aware of fire alarm signals and instruct them on the proper reaction to alarm signals.

• In rare instances, the sounding of a warning device can cause temporary or permanent hearing loss.

A fire alarm system will not operate without any electrical power. If AC power fails, the system will operate from standby batteries only for a specified time and only if the batteries have been properly maintained and replaced regularly.

Equipment used in the system may not be technically compatible with the control. It is essential to use only equipment listed for service with your control panel.

Telephone lines needed to transmit alarm signals from a premise to a central monitoring station may be out of service or temporarily disabled. For added protection against telephone line failure, backup radio transmission systems are recommended.

The most common cause of fire alarm malfunction is inadequate maintenance. To keep the entire fire alarm system in excellent working order, ongoing maintenance is required per the manufacturer's recommendations, and UL and NFPA standards. At a minimum, the requirements of Chapter 7 of NFPA 72 shall be followed. Environments with large amounts of dust, dirt or high air velocity require more frequent maintenance. A maintenance agreement should be arranged through the local manufacturer's representative. Maintenance should be scheduled monthly or as required by National and/ or local fire codes and should be performed by authorized professional fire alarm installers only. Adequate written records of all inspections should be kept.

If detectors are not so lo-

cal Services Department if any problems are anticipated or encountered.

Disconnect AC power and batteries prior to removing or inserting circuit boards. Failure to do so can damage circuits.

Remove all electronic assemblies prior to any drilling, filing, reaming, or punching of the enclosure. When possible, make all cable entries from the sides or rear. Before making modifications, verify that they will not interfere with battery, transformer, and printed circuit board location.

Do not tighten screw terminals more than 9 in-lbs. Over-tightening may damage threads, resulting in reduced terminal contact pressure and difficulty with screw terminal removal.

Though designed to last many years, system components can fail at any time. This system contains static-sensitive components. Always ground yourself with a proper wrist strap before handling any circuits so that static charges are removed from the body. Use static-suppressive packaging to protect electronic assemblies removed from the unit.

Follow the instructions in the installation, operating, and programming manuals. These instructions must be followed to avoid damage to the control panel and associated equipment. FACP operation and reliability depend upon proper installation by authorized personnel.

Charger Configuration

2.3 Charger Configuration

2.3.1 SW2 & SW3 SLC Addressing Switches

An addressable monitor module has been incorporated into the circuitry of the CHG-75 to allow a host FACP (Fire Alarm Control Panel) to monitor the charger condition via its SLC. This monitor module will create an open circuit condition when any local charger trouble occurs. If AC power is lost, the monitor module will create a short condition which will be seen by the FACP immediately, even if AC delay is enabled. By addressing and connecting the charger to an addressable control panel’s SLC, the panel can be programmed to monitor this module for activation.

Rotary switches SW2 & SW3 are used to address the CHG-75 for connection to the addressable control panel’s SLC. The switches must be set to a unique address which has not been programmed for any other device on the SLC

Installation and Configuration

To set the desired address, turn switch SW2 to the

ones

the

digit of the address. For example, to set the charger to address

tens

125

, position

SW2 so the arrow points to 12 and position SW3 so the arrow points to 5.

In the following example, the power supply has been set to address 68, with SW2 Tens switch pointing to 6 and SW3 Ones switch pointing to 8.

chg75add.cdr

2.3.2 SW1 SLC Communication Enable Switch

Slide switch SW1 is used to enable and disable the SLC communication between the CHG-75 and the FACP. Positioning SW1 to the left (ON) will enable SLC communication while positioning the switch to the right (OFF) will disable communication. Refer to Figure 2.1 on page 10, for the location of switch SW1.

Note that if the FACP has been programmed to monitor the charger via the SLC, positioning SW1 to the right (OFF) position will disable SLC communication between the charger and control panel, causing the FACP to indicate a communication fault for the charger address.

2.3.3 AC Loss Reporting Delay - Central Station Applications

If a Digital Alarm Communicator (DACT) is being used, the reporting of an AC loss condition to a Central Station must be delayed. This will delay the activation of the trouble bus and Form-C trouble contacts when the AC fails. The charger can be configured for an 8-hour or 16-hour delay as follows:

JP3

Refer to Figure 2.1 on page 10, for location of the jumpers.

JP4

- Leave jumper JP4 in to delay AC loss reporting for 8 hours

Cut jumper JP4 to delay AC loss reporting for 16 hours

Installation and Configuration

2.3.4 Ground Fault Detection Disable

Cut jumper ground fault detection circuit might be disabled when the charger is connected to equipment with its own ground fault detection circuit to prevent the two circuits. Note that Ground Fault detection is required in Canada. Refer to Figure 2.1 on page 10, for location of the jumper.

2.3.5 AM-1 Ammeter Enable

Cut jumper CHG-75 charger. Refer to Figure 2.1 on page 10, for location of the jumper.

2.4 Mounting the Charger

2.4.1 Mounting the Charger in an FACP

Trouble Monitoring

2.10 Trouble Monitoring

The CHG-75 charger has three connectors (J1, J2 & J3), a Form-C trouble relay (TB4) and an SLC (Signal Line Circuit - TB3) which can be used for trouble monitoring by an FACP. These connections are optional and, therefore, are not required for the proper operation of the charger. They are, however, necessary when the FACP is required to indicate a trouble condition for the charger. One or more of the following may be used to transmit the trouble condition to the FACP:

•

- Trouble IN (2-pin connector) Open collector input allows connection to trouble bus from other devices which are compatible with open collector inputs. This connection allows daisy chaining of trouble signals through the charger without affecting the charger operation or activating the local trouble relay.

•

- Trouble OUT (2-pin connector) Open collector output allows connection of trouble bus to other devices which are compatible with open collector outputs. This connection allows daisy chaining of trouble signals from the Trouble IN connector. A trouble on the charger will also be transmitted from this connector

•

- Trouble IN Master (2-pin connector) This input can receive trouble signals from another device, such as a spare zone, and will in turn activate the local trouble relay. This input is compatible with an open collector output from another device

Installation and Configuration

•

Figure 2.16 on page 24 provides an illustration of CHG-75 connector locations and terminal connections.

- Trouble Relay This fail-safe Form-C Trouble relay will activate when the charger detects a local trouble, such as AC fail, ground fault (if enabled), low battery, etc., or when a trouble signal is received at the Trouble IN Master (J7)
