Fire Alarm System Limitations
While a fire alarm system may lower insurance rates, it is not a substitute for fire insurance!
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.

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.

1. Introduction to the Charger
Overview
The CHG-120F battery charger is designed to charge lead-acid batteries that provide emergency standby power for a Fire Alarm Control Panel (FACP). Two 12-volt batteries are always used in series to supply 24 VDC nominal. The following list gives answers to some common questions about the charger:
What types of FACPs can be used with the charger? Any 24 VDC FACP that uses
lead-acid 25 AH to 120 AH batteries and that has the feature to disable the FACP battery charger.
Where does the charger mount? You can mount the charger in a CAB-A3F or
CAB-B3F Cabinet or in a BB-55F Battery Box.
How many outputs does the charger provide? The charger provides two output
circuits for connection to multiple loads (such as a power supply, amplifier, auxiliary amplifier, and so forth).
What options are available with the charger? You can configure the charger to
disable the charger’s ground fault detection, to delay AC loss reporting (8 or 16 hours), and to operate with 120 VAC or 240 VAC.
How long does it take the charger to charge batteries? Typically, it takes 9 hours to
charge 25 AH batteries, 20 hours to charge 55 AH batteries, and 38 hours to charge 120 AH batteries. Refer to “Specifications” on page 8 for details.

Connecting the Charger to a Load Installing the Charger
Adding the Charger for Additional Current Due to internal fuses, the maximum alarm current that can be drawn from the batteries and passed through the charger’s two output circuits is limited to 10 amps maximum (each circuit). The PS-12600 batteries, however, are capable of supplying up to 45 amps of current in alarm. The remaining 25 amps of alarm current can be drawn directly from the battery terminals to supply Notification Appliance Circuits, control modules and other alarm devices as illustrated in Figure 12

Installing the Charger Configuring the Charger
Configuring the Charger
The charger can be configured to do the following:
Receive 120 VAC or 240 VAC input power (see Figure 3 on page 11).
Delay AC loss reporting (for Central Station applications); and
Disable charger ground fault detection.
Figure 13 shows how to configure the charger for delaying the loss of AC reporting and for disabling ground fault detection:
Disable ground fault detection cut and remove R104
Delay loss of AC (16 hrs) cut and remove R100, in addition to cutting JP8
Delay loss of AC (8 hrs) cut only JP8
Delay loss of AC Reporting - If using a Digital Alarm Communicator (DACT), you must
delay the reporting of an AC loss condition to a central station. This delays activation of the trouble bus and Form-C trouble contacts when AC fails. You can configure the charger for an 8-hour or a 16-hour delay as follows:
8-hour delay – Cut and remove jumper JP8 on the charger (Figure 13).
16-hour delay – Cut jumper JP8; then, cut and remove resistor R100 (Figure 13).
Disable Ground Fault Detection - To disable local (charger) earth fault detection, cut and remove resistor R104 (Figure 13). Figure 14 contains a simplified block diagram that shows ground fault detection disabled on a charger connected to a power supply:
