Fire Alarm System Limitations

An automatic fire alarm system–typically made up of

smoke detectors, heat detectors, manual pull stations, audible warning devices, and a fire alarm control panel 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.).

PrecauSmall.PMD 01/10/2005

While a fire alarm system may lower insurance

rates, it is not a substitute for fire insurance!

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. If

detectors are not so located, 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 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.

Installation Precautions

WARNING - Several different sources of power can be

connected to the fire alarm control panel. Disconnect all sources of power before servicing. Control unit and associated equipment may be damaged by removing and/or inserting cards, modules, or interconnecting cables while the unit is energized. Do not attempt to install, service, or operate this unit until this manual is read and understood.

CAUTION - System Reacceptance Test after Software Changes. To ensure proper system operation, this

product must be tested in accordance with NFPA 72 after any programming operation or change in sitespecific software. Reacceptance testing is required after any change, addition or deletion of system components, or after any modification, repair or adjustment to system hardware or wiring.

All components, circuits, system operations, or software functions known to be affected by a change must be 100% tested. In addition, to ensure that other operations are not inadvertently affected, at least 10% of initiating devices that are not directly affected by the change, up to a maximum of 50 devices, must also be tested and proper system operation verified.

This system meets NFPA requirements for indoor dry operation at 0-49°C/32-120°F of 93 ±2% RH (non-condensing) at 32 ±2°C/90 ±3°F. However, the useful life of the system's standby batteries and the electronic components may be adversely affected by extreme temperature ranges and humidity. Therefore, it is recommended that this system and all peripherals be installed in an environment with a nominal room temperature of 15-27°C/60-80°F.

Verify that wire sizes are adequate for all initiating and indicating device loops. Refer to manual Specifications section for maximum allowable I.R. drop from the specified device voltage.

and at relative humidity

Adherence to the following will aid in problem-free installation with long-term reliability:

Like all solid state electronic devices, this system may operate erratically or can be damaged when subjected to lightning-induced transients. Although no system is completely immune from lightning transients and interferences, proper grounding will reduce susceptibility.

Overhead or outside aerial wiring is not recommended, due to an increased susceptibility to nearby lightning strikes. Consult with the Technical 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.

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.

LCD-80F Annunciator SW1 DIP Switch Settings

1.3 SW1 DIP Switch Settings

Refer to “DIP Switch Settings Example” on page 13, for an explanation of DIP switch positions. SW1 switch settings follow:

1 -ON = Key-switch disabled, OFF = Key-switch enabled.

Switch 1 set to the OFF position enables key-switch operation. The key-switch may now be used to enable the LCD-80F membrane switches, allowing remote switch functions, or lockout the switches, preventing remote switch functions

Switch 1 set to the ON position disables the key-switch operation. Refer to “Switch Functions” on page 16, for key-switch function description.

2 -ON = Piezo sounder enabled, OFF = Piezo sounder disabled.

CAUTION: Piezo sounder must not be disabled without prior approval of the Local Authority Having Jurisdiction (LAHJ).

3 -ON = Supervision Receive/Transmit, OFF = Supervision Receive Only.

• One Annunciator - if a single LCD-80F is the only annunciator

connected to the EIA-485 loop, Switch 3 must be set to the ON position to allow the FACP to supervise the annunciator.

• Multiple Annunciators - if multiple LCD-80F annunciators are

connected to the EIA-485 loop, the annunciator physically connected as the last device on the loop (farthest from the ‘OUT’ terminals on the FACP) must have Switch 3 set to the ON position in order to supervise all annunciators on the loop. All remaining annunciators must have Switch 3 set to the OFF position for proper supervision and operation.

It is important to note that the function switches on all LCD-80F annunciators will operate regardless of the setting of Switch 3.

A break (open circuit) in the power or EIA-485 connections creates an LCD-80F Annunciator fault at the control panel. All annunciators before the break will continue to display information (but the function switches on these LCD-80Fs will no longer operate).

Operation Switch Functions

2.2 Switch Functions

2.2.1 Key-switch

The key-switch is used to enable and disable the operation of the function switches if switch 1 on DIP switch SW1 has been placed in the OFF position.

To enable the Acknowledge, Silence, Drill and Reset function switches, insert key into keyswitch located at the top right corner of the LCD-80F. Make certain the key is inserted completely before attempting to turn it. Turn the key clockwise until it stops. Leave the key inserted while pressing the function switches. When finished with the function switches, turn key-switch counterclockwise to disable function switches.

Note that the key-switch should normally be in the disabled position (fully counterclockwise), with the key removed and access to the key restricted to authorized personnel only. Do not leave the key unattended in the LCD-80F.

Key-switch (shown in Off position)

TOR

Alm. Silenced

2.2.2 Acknowledge/Step

When the Acknowledge/Step switch is pressed and released, the LCD-80F sends an Acknowledge command to the control panel. Pressing the Acknowledge switch silences the local piezo sounder, the sounders located in all other system annunciators and the sounder located on the Fire Alarm Control Panel's main circuit board. Only one press is necessary regardless of the number of new alarms, troubles or supervisory signals.

An acknowledge message is also sent to the printer and the history files in the FACP. Multiple active events (alarms, troubles, supervisories) are scrolled on the display at a one second rate, but may be held for sequential display by pressing and holding the Acknowledge switch.

Document 51338 Rev. B 08/24/05 P/N 51338:B

Operation Switch Functions

When more than one event exists, the first press of the Acknowledge switch silences system piezo sounders. The second press of the switch stops the scrolling and holds the event on the display for one minute. Subsequent pressing of the switch 'steps' through each active event.

2.2.3 Silence

When the Silence switch is pressed and released, the LCD-80F sends an alarm silence command to the control panel. The Silence switch performs the same functions as the Acknowledge switch. In addition, if an alarm exists, it turns off all silenceable NACs and causes the FACP Alarm Silenced LED to turn on while the LCD-80F will display a 'silenced' message. It also sends an 'Alarm Silenced' message to the printer and the history file within the FACP. A subsequent new alarm will resound the appropriate NACs (Notification Appliance Circuits) and local sounders.

2.2.4 Drill: Hold 2 Sec.

When the Drill switch is pressed and held for at least two seconds (time required to prevent accidental activations), the LCD-80F will transmit a drill command to the control panel. This command causes the FACP to turn on all NAC outputs and all silenceable circuits (all control modules/NACs that are programmed silenceable). In the event that the system was previously silenced, the drill command will also turn off the Alarm Silenced LED. The 'Manual Evacuate' message is shown on the LCD-80F display. The same message is sent to the FACP display, printer and history files. The Silence switch operates on silenceable NAC outputs only.

2.2.5 Reset

When the System Reset switch is pressed and released, the LCD-80F sends a Reset command to the control panel. This will turn off all control modules and Notification Appliance Circuits, temporarily turns off resettable power to 4-wire detectors, causes a 'System All Normal' message to be displayed on the LCD-80F and sends a 'System Reset' message to the FACP display, printer and FACP history files. It also turns on all system LEDs, piezo sounders and LCD display segments as long as the Reset switch is held (lamp test). Any alarm or trouble that exists after a Reset will resound the system.

Operation LED Indicators

2.3 LED Indicators

2.3.1 AC Power

This is a green LED which illuminates if AC power is applied to the host FACP. The green LED will turn off if AC power to the host FACP is lost.

2.3.2 Alarm

This is a red LED that turns on steady when one or more fire alarms occur. The Alarm LED turns off when the Reset switch is pressed.

2.3.3 Supervisory

This is a yellow LED that turns on steady when one or more supervisory conditions occur, such as a sprinkler valve tamper condition. It turns off when the Reset switch is pressed.

2.3.4 Trouble

This is a yellow LED that turns on steady when one or more trouble conditions occur. The LED turns off when all trouble conditions are cleared. This LED will also illuminate if the microprocessor watchdog circuit within the LCD-80F is activated.

2.3.5 Alarm Silenced

This is a yellow LED that turns on when the Silence switch is pressed to turn off the Notification Appliance Circuits. The LED turns off when the NACs turn back on or when the alarm condition is cleared and the FACP is reset back to a normal condition.

Mounting Annunciator Preparation

Section 3: Mounting

3.1 Annunciator Preparation

The LCD-80F Annunciator can be surface mounted in a three-gang electrical box such as the P/N SBB-3 (2.75" depth) or semi-flush mounted in a three-gang electrical box, P/N 10103 or equivalent, with a minimum depth of 2 3/16". The LCD-80F Annunciator can also be mounted in three gangable electrical switch boxes connected together. Select and remove the appropriate knockout(s), pull the necessary wires through the knockouts and mount the box in or on the wall depending on the type of installation desired. Be certain that power is not applied to

the wiring during the installation procedure.

Note: To ensure static protection, all enclosures, including the LCD-80F electrical box, must be connected to earth ground! Never use the shield for grounding purposes.

To mount the LCD-80F Annunciator in an electrical box, the trim ring must first be removed. The trim ring is held in place by two screws inserted through the top and bottom edge as illustrated in Figure 3-1. Removal of the trim ring will expose a metal flange with mounting holes. Refer to “Hardware and Backboxes” on page 20.

Electrical Connections Power Connections

Section 4: Electrical Connections

4.1 Power Connections

The LCD-80F Annunciator can be powered by the FACP (refer to the specific technical manual for the proper connection of the LCD-80F) or from a remote UL listed, filtered power supply such as the FCPS-24FS6/8. The power run to the annunciator must be power-limited but need not contain a power supervision relay since loss of power is inherently supervised through loss of communication with the annunciator. Maximum LCD-80F current draw from the power supply (under normal and alarm conditions) is 64.3 mA. Maximum current draw from the control panel's secondary power source (batteries) under loss of AC power is 25 mA, since the LCD backlight is turned off during AC loss. Backlighting is turned back on during AC loss only for alarm conditions in the system.

3. 6,000 feet (1,800 m) maximum distance @ 18 AWG (0.75 mm between the FACP and first LCD-80F, between each LCD-80F and return to the FACP from last LCD-80F

4. Use overall foil/braided-shielded twisted pair cable suitable for EIA-485 applications (refer to “EIA-485 Shield Termination” on page 26, for shield termination information). Six conductor overall shielded wire may be used for the four EIA-485 wires and the two power wires. It is, however, strongly recommended that the power and communication wires be separate whenever possible

5. Ferrite Core P/N FBD-1 is required to meet FCC Part 15 requirements if the EIA-485 wiring is not in conduit

6. The EIA-485 circuit is rated at 5.5 VDC maximum and 60 mA maximum

7. The LCD-80F annunciator has resistors built into the circuit board at the In (Terminals 2 & 4) and the Out (Terminals 1 & 3) for impedance matching. There is no

need for the installer to add

impedance matching resistors

8. Enable FACP communication with the LCD-80F in the FACP programming if appropriate (refer to FACP manual)

EIA-485 Shield Termination EIA-485 Connections

Section 5: EIA-485 Shield Termination

The EIA-485 circuit must be wired using a twisted, shielded pair cable with a characteristic impedance of 120 ohms (+/- 20%). Do not run cable adjacent to or in the same conduit as 120 VAC service, noisy electrical circuits that are powering mechanical bells or horns, audio circuits above 25 V

Note: To ensure static (ESD - electrostatic discharge) protection, all enclosures, including the LCD-80F electrical box, must be connected to earth ground! Never use the EIA-485 shield for this purpose. The EIA-485 shield is for radiated noise emission protection (RFI, EMI). Refer to the following figures for details on EIA-485 shield termination.

EIA-485 Shield Termination Shield Not in Conduit

5.1 Shield Not in Conduit

The EIA-485 line allows the FACP to communicate with the LCD-80F Annunciator. The shield for the EIA-485 line must be connected to earth ground at the FACP but must be left floating (no connection) at the annunciator if it is the first or only device on the EIA-485 line. If a second annunciator is connected, the shield leaving the first annunciator must be left floating. The shield entering the second annunciator must be connected to the three-gang box or Earth Ground terminal (P2-7) on the second annunciator. If additional annunciators are connected, the shield leaving each enclosure must be left floating and the shield entering each must be connected to the three-gang box or the Earth Ground terminal (P2-7) on the annunciator.

EIA-485 Shield Termination Shield in Full Conduit

5.2 Shield in Full Conduit

The EIA-485 line allows the FACP to communicate with the LCD-80F Annunciator. The shield for the EIA-485 line must be connected to earth ground at the FACP (both exiting and entering the FACP) but must be left floating (no connection) at the annunciator if it is the first or only device on the EIA-485 line. If a second annunciator is connected, the shield leaving the first annunciator must be floating. The shield entering the second annunciator must be connected to the Earth Ground terminal (P2-7) on the second annunciator. If additional annunciators are connected, the shield leaving each annunciator must be left floating and the shield entering the following unit must be connected to the Earth Ground terminal (P2-7) on the annunciator.

Caution! Do not allow the floating shield end (no connection) to contact the conduit. The floating end should be insulated from earth ground.
