Test Test methods
Control panel
Visual inspection Inspect the equipment for any visible signs of
damage or other changes that may adversely affect
performance.
Initial and
Reacceptance
1. Verify that the control panel indicates open,
short, and ground faults for all notification
appliance circuits, initiating device circuits, and
signaling line circuits.
2. Verify that the control panel activates all
evacuation signals and auxiliary functions
according to the site specific software.
3. Verify that all controls and indicators are
working.
4. Disconnect the primary (mains) power. Verify
that the control unit indicates an AC power
failure.
Quarterly/Annual Test one-fourth of the entire system every three
months such that the entire system is te
sted in a one
year period, or test the entire system once each
year.
Standby
batteries Visual inspection
Inspect batteries for corrosion or leakage. Verify that
the battery connections are tight and secure. Clean
the connections, if required. Replace batt
eries every
five years or sooner if conditions warrant.
Initial and
Reacceptance
1.
With the control panel powered up, and with the
batteries connected and fully charged, verify the
voltage across the battery terminals is the
correct voltage in accordance with the battery
manufacturer's specifications.
2.
With the control panel under full load, disconnect
the primary (mains) power. Wait until the
standby operation time requirement passes then
activate all alarm signals. Verify that the alarm
signals remain active for at least 5 minutes for
horns and strobes or 15 minutes for audio in the
USA, whichever is greater.
