To change the priority settings, press on the priority button(s) you want to activate (green) or

12.2 Assign Priority Levels to Relays, Strobe, Horn & Audible
This setting enables you to assign priority levels to each relay, strobe, horn and/or audible
buzzer. One relay, strobe, horn or audible can be assigned to three priorities in combinations
of:
• AND (both priorities must be met to activate the relay)
• OR (either priority can activate the relay)
Using this AND and OR logic, the priorities can be combined in multiple ways, increasing the
number of possible configurable relay combinations.
To enter the Config Channel menu, enter code “3022” on the password screen, press Next
and select Relay Logic.

relay number by pressing the yellow field and using the keypad. Continue entering the
