When an alarm occurs the horn relay will change state and remain in the alarm condition until the
mute or ack pushbutton has been pressed. Each channel can be set to operate the critical horn relay
as required. Please note:- Channels set to operate the critical horn relay will also operate the integral
audible alarm.
5.3 Non-Critical Horn Relay - HNB
When an alarm occurs the relay will change state and remain in the alarm condition until the mute or
ack pushbutton has been pressed. Each channel can be set to operate the non- critical horn relay as
required. Please note:- Channels set to operate the non-critical horn relay will not operate the integral
audible alarm.
