6.2.4 General Fault relay
The General Fault relay is usually in energized state and volt-free /
potential-free. It is de-energized in Fault condition.
Contact range: max 30 V AC / DC, 1 A, non-inductive loads.
Settings: NO contact (Jumper JGST).
6.2.5 General Alarm relay
The General Alarm relay is usually in energized state and volt-free /
potential-free. It is de-energized in Fire condition.
Contact range: max 30 V AC / DC, 1 A, non-inductive loads.
Settings: NO contact (Jumper JALL)
