SETTING THE TIME OUT
The total time out is calculated by adding the count of the switches that are “ ON “ as shown below,
PLUS one (1) and then multiplying this total by the base time. The base time is usually ten seconds
unless stated otherwise.

Example: Switches numbered 2 + 3 are ON, all others are OFF
The count for the Timeout is therefore = (2 + 4 + 1) x 10 = 70 seconds
Switch 7 (if ON) halts evacuation sequences when the key switch is in the Manual position. See section
8.1.2 for further detail.
Switch 8 (if ON) enables monitoring of the EIS and EWS audio bus. See section 10.3 for further detail.
