TRIGGER TYPE: The trigger type is selectable to "REMOTE" or "INTERNAL." Selecting INTERNAL mode uses the internal trigger sensor to activate the Exit Delay cycle. Selecting REMOTE mode disables the internal trigger. Activation of the Exit Delay cycle is triggered by an external exit device equipped with a normally open contact switch.

POWER-UP OPTION: The power-up option, indicating the state of the ExitCheck upon restoration of system power, is selectable to "unlocked" or "locked." In the locked mode, the ExitCheck will attempt to reset to secure mode. In the unlocked mode, the ExitCheck will remain unlocked and the digital display will indicate two horizontal bars "--". Turning the reset switch momentarily to the reset position will relock and rearm the door. This feature enables the ExitCheck to comply with code requirements in jurisdictions that require manual reset/relock upon loss and restoration of system power.

ALARM TYPE: The alarm type is selectable to "TONE ONLY" or "VOICE." When secure, the ExitCheck digital display will indicate a 15-second delay time. Upon activation of the irreversible Exit Delay cycle, the digital display begins counting down to zero. In VOICE mode, the countdown will be accompanied by a warning beeping tone and verbal exit instructions. When the digital display indicates zero, the ExitCheck releases. The speaker output changes to a continuous warning tone and the verbal instruction announces "Exit Now." In TONE ONLY mode, the countdown will be accompanied by a warning beeping tone only, which changes to a continuous tone once the Exit Delay cycle expires.

MESSAGE TYPE: The message type is selectable to "MSG2" or "MSG1." MSG1: (Female Voice): "Facility staff has been alerted, door will open in 12 seconds...door will open in 5 seconds...exit now..." MSG2: (Male Voice): "Security has been alerted, door will open in 12 seconds... door will open in 5 seconds...exit now..." Both messages repeat "Exit now" until the lock is reset.
