7.1.4 ENTER and RESET/ACK Switch
This switch has a multiple-use purpose. The ENTER function is used to accept selections within all
menu screens. The Enter switch is also used to execute the Reset and Acknowledge functions. The
Reset function releases all latched relays if they have cleared the alarm/fault condition. The
Acknowledge function will disengage any silenceable relays that are in a currently active state. This is
typically used to silence alarm annunciators, once the end-user has assessed the alarm condition. The
RESET/ACKNOWLEDGE switch is only functional from the Main Display and not while in Menu
Mode.
