Periodic testing and maintenance of the FACP, all initiating and notification
devices, and any other associated equipment is essential to ensure proper and
reliable operation. Test and maintain the FACP according to the schedules and
procedures outlined in the following publications:
• NFPA Standard 72-1996, Chapter 7, “Inspection, Testing, and
Maintenance.”
• Installation Instructions for the peripheral devices installed in your system.
Correct any trouble condition or malfunction immediately.
Periodic testing and maintenance of the system batteries must be done to ensure
proper and reliable back-up operation. Test and maintain the system batteries
using the following information.
All sealed lead-acid batteries in fire alarm service should be tested annually.
Replace all sealed lead-acid batteries that have been in service for four or more
years.
It is recommended that a battery tester made specifically for checking sealed
lead-acid batteries be used. Such a tester is available under Service Part No.
553-602.
If a battery tester is unavailable, the “voltage response test” described in the
following information can be used to detect batteries with very low capacity or
shorted cells.
Caution: A defective battery charger circuit can cause battery failure.
Check the condition of the battery charger when either a
battery tester or a voltage response test reveals weakened
batteries.
Voltage Response Test
1. Disconnect battery from system.
2. Connect a digital voltmeter across the battery.
3. Connect the appropriate sized resistor(s) (see Table 3-1) across the battery’s
terminals for the listed test time.
Caution: Resistors will get hot during test! Use 12AWG wire for
battery-to-resistor hookup.
4. Record the end voltage reading.
5. Treat the battery as described in Table 3-2.
