5-3.4 Lamp Test
Use the following procedures to perform the lamp/buzzer test.
1. Verify that the control unit is in normal standby mode with no alarms, troubles or
supervisory conditions.
2. Press and hold the Acknowledge control switch for a period of five (5) seconds. The LEDs
and the digital display characters will illuminate, and the buzzer will sound. This will
continue until the Acknowledge control switch is released, or there is a status change to
the control unit. This will enable malfunctioning LEDs/segments to be visually sighted.
