Figure 15. Wire Doors
1. Wire the REX & DOOR terminal block.
a) Connect the Normally Open (NO) contacts of the REX device to the REX and
COM terminals.
• When this switch closes, it initiates a Request-to-Exit (REX) program
sequence, as defined by ACS Online, including the option to activate the
door or other relays, fire the door strike, and suppress any “Door Forced”
messages.
b) Connect the Normally Closed (NC) contacts of the Door Sensor to the COM and
CONTACT terminals.
• In this context, an NC switch is considered closed when the door is
closed (magnet is present), and open when the door is open (no magnet
is present).
• When the switch is open, the control panel interprets this input as a
“Door Open” condition. When the switch is closed, the control panel
interprets this input as a “Door Closed” condition.
• This circuit provides door status information (open/closed) to the control
panel so ACS Online can take appropriate action locally, or send email
notifications if necessary.
