PN 50888:B0 ECN 01-155 Battery Charger CHG-120F Installation & Operating Manual Document 50888 03/21/2001 Rev: B
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 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: Note: Throughout this manual, the term “charger” refers to a CHG-120F.
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 reporting delay for loss of AC (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 24 VDC Secondary input power (use in battery calculations for FACP) 60 mA - cur
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. 9 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.
Installing the Charger Connecting AC Power to 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 - 25 AH –120 AH batteries can be connected to the charger. This section provides illustrations and instructions for connecting two batteries or for connecting four batteries. Connecting Two Batteries - Figure 5 illustrates how to connect two 25 AH batteries to the charger: TB2 ! Warning: Do not connect the Battery Interconnect Cable at this time. Refer to “Starting the Charger” on page 25.
Installing the Charger Connecting Batteries to the Charger Connecting Four Batteries - Figure 6 illustrates how to connect four 55 AH batteries to the charger: TB2 ! Warning: Do not connect the Battery Interconnect Cable at this time. Refer to “Starting the Charger” on page 25. 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-A3F or CAB-B3F A charger can be mounted into the bottom row of a CAB-A3F or CAB-B3F 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-A3F or CAB-B3F—next to the power supply (Figure 7, position 2). If using an additional CAB-A3F or CAB-B3F, the charger can be mounted in the lower left corner (Figure 7, position 2).
Installing the Charger Mounting the Charger Mounting the Charger in a BB-55F Battery Box A charger can be mounted in a BB-55F battery box, provided the BB-55F is within 20 feet of the load. Note that a charger takes up half the space in the BB-55F. This means there will be space remaining for only two 25 AH batteries in the BB-55F. Figure 8 illustrates the mounting position of a charger in a BB-55F.
Installing the Charger Connecting the Charger to a Load Connecting the Charger to a Load This section provides four applications for connecting a charger to a load. While connecting a charger to a load, observe the following precautions: Note: Figure 12 is a wiring diagram which illustrates the connection of a load to battery terminals in order to obtain additional current. • Make sure all power has been removed from the charger and the load. • Observe polarity when making connections.
Installing the Charger Connecting the Charger to a Load Connecting the Charger to an MS-9200 - A charger can be connected to an MS-9200 (requires MS-9200 circuit board #71741, or later) by disabling the local charger by cutting jumper JP1 as illustrated in Figure 10.
Installing the Charger Connecting the Charger to a Load Connecting the Charger to an MS-9600 - A charger can be connected to an MS-9600 as illustrated in Figure 11.
Installing the Charger Connecting the Charger to a Load 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 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.
Installing the Charger Trouble and Form-C Relay Connections (Optional) 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 spare zone.
Installing the Charger Installing Optional Meters Installing Optional Meters You can also order and install a ammeter (AM-1), voltmeter (VM-1), or both (MPM-3) for use with the charger. If mounting an AM-1 or a VM-1, mount the meter to a BB-55F as shown in Figure 16. If mounting an MPM-3, mount to a power supply (Figure 17) installed in a CAB-A3F or CAB-B3F. 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.
Installing the Charger Installing Optional Meters Installing a VM-1 - A VM-1 can be connected across a charger output circuit. For example, to install a VM-1 to measure voltage from charger output circuit 1, follow these steps: 1. Mount the VM-1 into a mounting slot on the front of the BB-55F battery box. 2. Connect the positive lead to TB2 Out 1 (+). See Figure 15. 3. Connect the negative lead to TB2 Out 1 (–). SeeFigure 15. Installing an MPM-3 To install an MPM-3, follow these steps: 1.
