Fire Control Instruments 14-16 Southwest Park Westwood, MA 02090, USA Phone: (781) 471-3000 FAX: (781) 471-3099 CHG-120 Battery Charger Instruction Manual FCI P/N 9000-0572 Document 52459 11/22/04 PN 52459:A Revision: ECN 04-691 A
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.
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. Control unit and associated equipment may be damaged by removing and/or inserting cards, modules, or interconnecting cables while the unit is energized.

1. Introduction to the Charger Overview Note: Throughout this manual, the term “charger” refers to a CHG-120. The CHG-120 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.
Introduction to the Charger Specifications The charger also provides the following features: • AM-1 ammeter (0-10A) ordered separately • VM-1 voltmeter (0-50 V) ordered separately • Disable local ground fault detection • Selectable loss of AC delay (8 or 16 hours) Specifications Table 1 contains electrical specifications for the charger: Primary AC power in (TB1) 120 VAC, 60 Hz, 2 A 240 VAC, 50 Hz, 1 A Form-C relay (TB3) 5 A at 30 VDC Float charge voltage 27.
2. Installing the Charger Overview This section contains instructions and illustrations for installing the charger, divided into the following topics: Section Topic(s) Covered Page Installation Precautions and Standards Precautions to take when installing the charger and recommended installation standards. 3 Charger Connections, Jumpers, and Switches Location and references to connections, jumpers, and switches used to configure, maintain, and operate the charger.
Installing the Charger Charger Connections, Jumpers, and Switches Installation Standards An installer should be familiar with the following standards: • NEC Article 300 Wiring Methods. • NEC Article 760 Fire Protective Signaling Systems. • Applicable Local and State Building Codes. • Requirements of the Authority Having Jurisdiction.
Connecting AC Power to the Charger Installing the Charger Connecting AC Power to the Charger Caution: Before connecting AC power to the charger—make sure to set the Voltage Select Switch (SW1) on the charger (Figure 2) to match your AC power source (120 VAC or 240 VAC). Figure 3 shows the voltage selection positions for SW1: Note: The charger is rated for 120 VAC or 240 VAC operation. Therefore, 115V on SW1 indicates 120 VAC operation; and 230V, indicates 240 VAC operation.
Installing the Charger Connecting Batteries to the Charger Connecting Batteries to the Charger Overview you can connect 25 AH –120 AH batteries to the charger. This section provides illustrations and instructions for connecting two batteries or for connecting four batteries. Connecting Two Batteries Figure 5 shows how to connect two 25 AH batteries to the charger: TB1 TB2 ! CHG-120 Warning: Do not connect the Battery Interconnect Cable at this time.
Connecting Batteries to the Charger Installing the Charger Connecting Four Batteries Figure 6 shows how to connect four 55 AH batteries to the charger: TB1 TB2 ! Warning: Do not connect the Battery Interconnect Cable at this time. Charger Power Supply Refer to “Starting the Charger” on page 15. Figure 6 Connecting Four Batteries to a Charger Table 4 contains instructions for connecting four batteries to the charger: Step Action 1 Remove all power sources to the charger.
Installing the Charger Mounting the Charger Mounting the Charger Mounting the Charger into a CAB-X3 Series Cabinet You can mount a charger into the bottom row of a CAB-X3 Series Cabinet, as long as the charger is within 20 feet of the load. Typically, a charger mounts into the lower right corner of the CAB-X3—beside the power supply (Figure 7, position 2). If using an additional CAB-X3, you can mount the charger in the lower left corner (Figure 7, position 2).
Mounting the Charger Installing the Charger Mounting the Charger into a BB-55 Battery Box You can also mount a charger into a BB-55 battery box, as long as the BB-55 is within 20 feet of the load. Note that a charger takes up half the space of the BB-55. This means you only have room left for two 25 AH batteries in the BB-55. Figure 8 shows the mounting position of a charger in a BB-55.
Installing the Charger Connecting the Charger to a Load Connecting the Charger to a Load This section provides two applications for connecting a charger to a load. While connecting a charger to a load, observe the following precautions: • Make sure all power sources are off to the charger and the load. • Follow polarity when making connections.
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.
Installing the Charger Configuring the Charger Configuring the Charger You can configure the charger to do the following: • Set the charger input power (see Figure 3 on page 5). • Delay AC loss reporting (for Central Station applications); and • Disable charger ground fault detection.
Trouble and Form-C Relay Connections (Optional) Installing the Charger Trouble and Form-C Relay Connections (Optional) Table 5 contains descriptions of optional connectors on the charger: Function Connector Use open collector input and output to daisy chain a trouble signal through the charger without affecting charger operation. JP5 Open Collector Trouble In JP4 Open Collector Trouble Out Receive trouble signals from another device, such as a Control Module.
Installing the Charger Installing Optional Meters Installing Optional Meters You can also order and install a ammeter (AM-1) or voltmeter (VM-1) for use with the charger. If mounting an AM-1 or a VM-1, mount the meter to a BB-55 as shown in Figure 14. Table 6 contains descriptions and part numbers for these optional meters: Item Part Number Description Ammeter AM-1 0-10 A ammeter with a 3-ft. cable for connection to the charger (JP3). Mounts into a BB-55 battery box only.
3. Operating the Charger Overview This section contains information on starting the charger, interpreting the LED Status Indicators on the charger, and normal operation of the charger. Starting the Charger ! Warning: Before starting the charger, do the following: Follow the installation instructions in Section 2, “Installing the Charger.” Verify proper polarity on all connections between the charger and the batteries, load, and optional meters.
