Fire-Lite CHG-75 Battery Charger - Manual (Page 8)

Product Description Specifications
8 CHG-75 PN 51315:A 08/01/01
1.2 Specifications
Primary (AC) Power - TB1, Terminals 1 (Hot), 2 (Neutral) & 3 (Earth)
120 VAC, 60 Hz, 2.05 amps maximum
220/240 VAC, 50 Hz, 1.14 amp maximum (JP1 cut)
Fuse F1 - 6.25 amp (slow blow 3AG)
Wire size: minimum 14 AWG with 600 volt insulation
Secondary Power (Battery) Charging Circuit - TB2, Terminals 1 (+) & 2 (-)
Supports lead-acid batteries only
Float Charge Voltage: 27.6 VDC
Maximum Charge Current: 4.5 amps (peak)
Maximum Battery Capacity: 75 AH
Supervised and Current-limited: F2 - 15 amp replaceable fuse
24 VDC Secondary (Battery) Input Power
The CHG-75 current consumption from the battery is as follows:
• During AC Loss: 60 mA
• With AC Present: 0 mA
Note: use these values in battery calculations for host FACP
Battery Output - TB2, Terminals 3 (+) & 4 (-)
Provides battery backup connection to other loads
Current-limited: F3 - 15 amp replaceable fuse
SLC (Signal Line Circuit) Connector - TB3, Terminals 1(B+), 2(A+), 3(B-) & 4(A-)
Provides connection to an addressable FACP (Fire Alarm Control Panel) SLC loop. A
built-in addressable monitor module can be used to indicate a charger trouble condition
or loss of AC by programming the FACP to monitor the address assigned to the charger.
Voltage: 24 VDC nominal, 27.6 VDC maximum
Maximum Loop Current: 400 mA (short circuit) or 100 mA (normal)
Maximum Loop Resistance: 40 ohms
Supervised and Power-limited
Trouble Contact Rating - TB4, Terminals 1 (C), 2 (NO) & 3 (NC)
Fail-safe Form-C Relay Contacts: rated for 2 amps @ 30 VDC (resistive)
Trouble In and Out Connectors - J1 (In) & J2 (Out)
Trouble In is an open collector circuit which can be used to monitor trouble conditions
on other equipment. It can be connected to the trouble bus of a peripheral, such as a
power supply, which is compatible with open collector circuits.
Trouble Out can be used to send the Trouble In signal and/or charger trouble signal to a
monitoring circuit on an FACP (daisy chain).
Trouble In Master - J3
Circuit monitors trouble from other devices by looking for a ground condition. When
input is brought to ground potential, charger will operate trouble relay
