04  Supervisory

Classifies the zone as a fire supervisory. All alarms are instant and will turn on the buzzer 
instead of the bell. Pressing the Trouble Silence Switch silences the supervisory buzzer. If a 
Supervisory occurs while there is another zone alarm, the Signal Silence switch will silence 
both the Alarm and Supervisory conditions. Silencing a Supervisory Alarm does not activate 
the Signal Silenced trouble.

05  Four Wire Smoke (only) Auto Verify

Smoke detectors on that zone will be verified before an alarm is initiated. If this type of alarm 
occurs with an alarm present on the system, or the auto-verify timer active, this zone will 
become an instant alarm.

WARNING: 

Manual Pull Stations MUST NOT be used on this zone type.
