Note: To automatically unlock the door in case of fire, remove the Fire Alarm
Bypass wire and connect J18 to the Fire Alarm panel as per Fire Alarm
Panel Wiring diagram (see Annex B, Figure 10).
In this case the Electromagnetic Lock MUST be powered from the
RAC 4XT’s +12V output as shown in this diagram.
