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 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 72-1999 (NFPA 72-1999), 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 firstfloor 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.).

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 panel. 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 72-1999 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

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

WARNING – Several different sources of power can be connected to the fire alarm control panel. Disconnect all sources of power before servicing. The 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 72-1999 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°C to 49°C (32°F to 120°F) and at a relative humidity (noncondensing) of 85% at 30°C (86°F) per NFPA, and 93% ± 2% at 32°C ± 2°C (89.6°F ± 1.1°F) per ULC. 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. Most devices cannot tolerate more than a 10% I.R. drop from the specified device voltage.

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.

2.5 Intelligent Detectors
Introduction
Intelligent, addressable detectors provide analog information to the control panel on a Signaling Line Circuit (SLC). This allows the control panel to continually process this information to determine the status (alarm, trouble, maintenance, or normal) of each detector. Each detector responds to an SLC address that is set in the detector head using built-in rotary switches. Each SLC loop can support up to 159 detectors. The sensitivity of each intelligent detector can be programmed (refer to Appendix C in the NFS-640 Programming Manual for details).
Note: A blinking LED on an intelligent detector indicates communication between the detector and the control panel.
Detectors
The FlashScan® algorithm provides high-speed communication between analog intelligent devices, by polling in groups unless new information is reported. If one of the devices within the group has new information, the control panel stops the group poll and concentrates on single points. CLIP (Classic Loop Interface Protocol) is standard polling of each intelligent devices.
FAPT-851 (Acclimate PlusTM). Intelligent detector that combines a photoelectric sensing chamber and fixed temperature heat detection (135°F/57.2°C). FlashScan capable.
FSI-851. Addressable, intelligent smoke detector that incorporates an ionization sensing chamber. Designed to provide open area protection. FlashScan capable.

Laying Out Equipment in Cabinet and Chassis

3.4 Laying Out Equipment in Cabinet and Chassis
The NFS-640 allows for flexible system design. Follow these guidelines when deciding where to locate equipment in the backbox.
The first row of equipment mounts in chassis CHS-M2. Mount second, third, or fourth rows of equipment in chassis CHS-4N (panel circuit modules, see Section 3.7 “Installing Panel Circuit Modules”), or in chassis CHS-4L (voice components, see the Voice Alarm System Manual). Some equipment, such as the NCA and annunciators, may be door-mounted; refer to the equipment’s documentation for instructions.
There are four basic positions available on a chassis (side-by-side); the number of modules that can be mounted in each position depends on the chassis model and the module size.
The CHS-M2 accepts four layers of equipment, including the control panel. The control panel fills three positions in the first-installed layer, its integral power supply occupies two positions in the next two layers, and the optional display occupies the two left-most slots in the fourth layer (flush with the door). Panel circuit modules and other modules of the same sizing can be mounted in several layers, depending on the desired configuration; see Table 3 to determine hardware. Some equipment, such as the NCA, may be door-mounted directly in front of the control panel. The BMP-1 Blank Module Plate covers unused positions in a dress-panel, providing another mounting location for some modules, such as TM-4 (see BMP-1 Product Installation Drawing for details).

Installing the Control Panel

3.5 Installing the Control Panel
3.5.1 Control Panel Circuit Board & Keypad/Display Unit
The control panel mounts in chassis CHS-M2, which is usually positioned in the top row of the backbox. The control panel’s CPU occupies three positions at the back of the chassis; the KDM-2 occupies two positions flush with the door. The NCA may be door-mounted directly in front of the control panel if no KDM-2 is being used; see the NCA Manual for details and restrictions.
Note: For initial release of NFS-640, mounting instructions were different. Refer to the installation manual shipped with the panel (Rev A).
1. Verify height of the mounting stud in the backbox. In older backboxes, the stud must be shortened to prevent damage to the CPU-640. All electronics must be removed from the backbox before shortening. See instructions in the warning below.
WARNING: For retrofit applications, verify the height of the backbox’s mounting stud on left side ! under CPU, as shown in Figure 7 below. Stud height must not exceed 0.375 in. (9.525 mm). Early
versions of the CAB-4 Series backboxes and all CAB-3 Series backboxes have studs that require shortening. Failure to shorten this 0.625 in. (15.875 mm) mounting stud will cause damage to the control panel’s CPU. Remove electronics from backbox, permanently mount empty CHS-M2 chassis to backbox, apply nut to mounting stud to protect threading, then cut stud to proper length. Reinstall electronics as discussed in the steps below. WARNING: Do not cut without washers and nuts in place to protect threading. ! Wear protective eye covering.

If using a new CHS-M2 in a CAB-3 series backbox or in a CAB-4 series backbox manufactured before October 2002, verify stud height and cut any stud that exceeds 0.375 in. (9.525 mm) as per Step 1 above if a CPU is being mounted above it. Reinstall electronics as discussed in the steps below.

CHS-M2-11-03-CAB-3.wmf

Figure 7 Using the Redesigned CHS-M2 with Older Backboxes
2. Screw chassis to the backbox.
3. Attach CPU-640 to the chassis. Slide control-panel tabs into slots on chassis and lay the board onto stand-offs so that mounting holes line up with those on the chassis. Secure with six (6) screws (four across the top of the board, and two to the left of the power supply) provided with the chassis. (See Figure 8.)
4. If installing KDM-2, install the stand-offs included with the keyboard kit. (See Figure 8.)
· The upper edge of the keyboard mounting plate rests on two stacked pairs of male-female stand-offs. Connect P/N 42185 (2.0 inch, 50.8 mm) to P/N 42186 (1.312 inch, 33.33 mm).

CHS-M2-0604-assy.wmf

Attach two (0.937 inch, 23.8 mm) stand-offs to chassis rail; screw keypad mounting plate to the stand-offs.

Lower edge of panel circuit modules slide into chassis slots, and upper edge mounts onto PEM studs on the chassis flange.

Figure 8 Locating and Aligning Stand-offs for Keypad/Display and Panel Circuits (Chassis CHS-M2 shown)
3.5.2 Using NCA as Primary Display
The NFS-640 can be set up to use an NCA instead of a KDM-2. In this system design, connect the network port on the NFS-640 (J1) directly to the network port on the NCA (J3); see the NCA Manual for specific instructions.
Note: This system design is required in Canadian stand-alone applications.
If the NFS-640 and NCA are being used as a stand-alone pair, each device must be programmed separately using VeriFire Tools in its off-line programming mode. Because the VeriFire Tools computer also uses the network port, NFS-640 and NCA must be temporarily disconnected for programming. If the NFS-640 with NCA is connected to a network, there are two additional options for programming: either connect the VeriFire Tools programming PC to the network port on the NCM board, or program the NFS-640 through another network node. (See VeriFire Tools on-line help for details.)

Installing Panel Circuit Modules

3.7 Installing Panel Circuit Modules

3.7.1 Overview

Installation of a panel circuit module is divided into five (5) operations: · Mounting an optional expander board to the module (e.g. mounting ICE-4 onto an ICM4RK). · Connecting communication ribbon cables from Control Panel to the module. · Installing the module onto a chassis. · Connecting modules to the power supply. · Field wiring the module.
Refer to Section 2.10 “Panel Circuit Modules” for a complete list of modules and their expanders.

3.7.2 Mounting Expander Boards

Expander Board Modules, such as ICE-4 or CRE-4, need to be mounted onto their respective modules (ICM-4RK, CRM-4RK) prior to installation onto a chassis. To mount an Expander Module:
1. Remove one module support screw and set it aside for later use.
2. Replace the module support screw with one module stand-off.
3. Repeat Steps 1 and 2 for the three remaining module support screws.
4. Insert pins on the front of the expander board into connector on the back of the module. Make sure the pins are in line; then, press the two units together until they snap into place.
5. Install the four module support screws (removed earlier) through the back of the expander board and into the stand-offs. Tighten securely.
Figure 21 illustrates the steps.

3.9.2 Installing and Configuring the PRN-5 Printer

When connected to the Control Panel via an EIA-232 interface, the PRN-5 prints a copy of all status changes within the control panel and time-stamps the printout with the time of day and date the event occurred. It provides 80 columns of data on standard 9″ by 11″ tractor-feed paper.
Note: You can also use the EIA-232 printer interface with UL-listed I.T.E. equipment, such as personal computers, to monitor the control panel for supplementary purposes.
This section contains information on connecting a printer to the control panel and for setting the printer options.

Connecting a Remote PRN Printer
Remote printers require a 120 VAC, 50/60 Hz primary power source. If required for the fire alarm system configuration (for example, a Proprietary Fire Alarm System), a remote printer requires a secondary power source (battery backup). Because a secondary power source is not provided, use a separate Uninterruptable Power Supply (UPS) that is UL-listed for Fire Protective Signaling. You
