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 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 particles 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.).

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 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.

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 Chapter 7 after any programming operation or change in site-specific 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 operation at 0-49° C/32-120° F 85% RH (non-condensing) at 30° 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. Most devices cannot tolerate more than a 10% I.R. drop from the specified device voltage.

and at a relative humidity of

C/86° F. However,

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.

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.

1. Introduction

General

The ACM-8RF Relay Control Module contains eight high current (5 amps) Form-C relays. The module interfaces to host Fire•Lite control panels which employ an EIA-485 communications bus and may be connected to the bus up to 6,000 feet away from the host control panel.

Typically, each relay is assigned to a zone on the host fire alarm control panel. The relays may be triggered by either a zone alarm (activation) or zone trouble. The relays may also take on special functions depending upon the host panel. Refer to the Appendices for additional information.

The ACM-8RF Relay Control Module may be used in combination with the following products on the same EIA-485 bus circuit:

• AFM/ACM Series LED annunciators

• LDM Series graphic annunciators

• UDACT-F (Universal Digital Alarm Communicator/Transmitter)

• LED-10 Annunciator

EIA-485 bus compatible accessories are designed to provide maximum flexibility to system configurations. Examples include multiple remote LED annunciators with customized labels per corresponding area or function, multiple remote graphic annunciators that illustrate building layout and floor plans, remote DACTs for strategic mounting location near telephone equipment plus remote high current switching relays for such purposes as fan and damper control, elevator recall and door releasing.

SW1-SW2 Address Select Rotary Switches

The Relay Control Module provides eight Form-C relays with 5 amp contacts @ 125 VAC (resistive) or 30 VDC (resistive) and 2 amps at 125 VAC inductive). The relay contacts are gold plated silver alloy for medium duty switching and are not intended for motor control or pilot duty. Wiring to the relays is via sturdy removable terminal blocks.

24 VDC Power and Earth Ground

Wiring to removable terminal block TB1 is for 24 VDC power-limited, regulated, nonresettable power from the host FACP or a compatible UL listed battery backed power supply such as the Fire•Lite FCPS-24F. This terminal block may be used to daisy chain the 24 VDC to other ACM-8RFs or EIA-485 Fire•Lite compatible devices.

ACM-8RF PN 50362:C 03/21/01

EIA-485 Communications

Wiring to removable terminal block TB2 is for communications over the EIA485 bus. The bus carries commands and data sent between the host FACP and ACM-8RFs. The EIA-485 circuit is power-limited. The host FACP supervises devices wired to the EIA-485 bus. A maximum of 32 ACM-8RFs may be connected to the FACPs EIA-485 bus, but if other types of devices are also connected to the bus, the maximum number of ACM-8RFs must be reduced by the total of such devices.

Address Switches

Two rotary BCD (Binary Coded Decimal) switches, located on the lower right of the module, are used to set the ACM-8RF system address. SW1 represents the 'tens' position and SW2 represents the 'ones' position of the address setting.

Relay Function Selection

DIP switch SW3 is used to program the assignment of each ACM-8RF relay to either a zone function (such as zone alarm or zone trouble triggering) or to a system function (such as system alarm, system trouble, system supervisory, signal silence, pre-alarm or AC fail). Be certain to review the Appendices for information on SW3 switch settings for specific FACPs and the operation and options available to each host FACP.

Mode Selection

DIP switch SW4 is used to set the mode of operation for the ACM-8RF as follows:

• #1 sets Alarm activation or Alarm/Trouble activation mode.

• #2 sets Receive or Receive/Transmit mode.

2. Installation

Mounting the Enclosure.

Select and remove the appropriate knockout(s) on the ABS-8RF enclosure.

Securely mount the enclosure.

Ground the enclosure to a solid electrical ground per NEC Article 250.

Pull all wiring into the enclosure (refer to "UL Power-limited Wiring Requirements" on page 17).

Wiring the Power Terminal Blocks

24 VDC power supplied by the host control panel or external power supply must be regulated and power-limited. Th is power is inherently supervised (loss of power also results in a communication failure at the control panel).

• Limit the total wire resistance to 10 ohms.

• Connect 24 VDC power from FACP or Power Supply to TB1-3 (+) and TB1-4 (–).

• Connect earth ground (TB1-1 backbox or cabinet.

Wiring the EIA-485 Terminal Blocks

Communications between the Fire Alarm Control Panel and the ACM-8RF is accomplished over a two-wire EIA-485 serial communications bus which must be power-limited. Communications between the host FACP and ACM-8RFs is supervised by the fire alarm control panel.

Wiring Specifications

• The EIA-485 circuit cannot be T-tapped; it must be wired in a continuous fashion from the control panel to the ACM-8RFs.

• The maximum wiring distance between the panel and ACM-8RFs is 6,000 feet.

• The wiring must be a 18 AWG to 14 AWG twisted shielded pair cable having a characteristic impedance of 120 ohms, +/- 20%.

• Limit the total wire resistance to 100 ohms.

• Do not run cable adjacent to, or in the same conduit as, 120 volts AC service, noisy electrical circuits that are powering mechanical bells or horns, audio circuits above 25 V power circuits.

Note: Never use the EIA-485 shield for grounding purposes. Terminate the EIA-485 shield at the Fire Alarm Control Panel only.
