2 seconds (to prevent accidental activations), then turns on all silence-
able circuits (all FCM-1 modules/bell circuits that are programmed
silenceable), and turns off the Signals Silenced LED. It sends a Drill
Activated message to the LCD display, FDU-80, printer, and History
file.

Section 5 Periodic Testing and Maintenance
To ensure proper and reliable operation, system inspection and testing
should be scheduled monthly, or as required by NFPA 72 or local fire
codes. A qualified Service Representative should perform testing.
Before Testing:
Notify fire department and/or central alarm
receiving station if alarm condition is transmitted. Notify facility per-
sonnel of the test so alarm sounding devices are ignored during the test
period.
After Testing:
Notify all fire, central station, and/or building per-
sonnel when testing is complete.
