and reliability as if the access system experiences a fault, the XMS still allows safe egress. If the
access system is not monitoring the door, connection to the REX input is not required. In that
case, make all other connections as shown in Figure 5 except the REX input.

3.5 “ACCESS CONTROLLED EGRESS DOOR”
In some jurisdictions, the combination of a magnetic lock, access control system and exit
detector such as the XMS can be considered an “access controlled egress door”. The applicable
section of the Life Safety Code calls for a redundant means of exit in the event of a problem with
the detector. This is typically a push button located 40-48” above the floor and within five ft. of
the door. Pushing the button will directly release power to the magnetic lock and the lock shall
remain released for 30 seconds. This can be accomplished with any of Securitron’s push buttons
and the model TM-8L timer. Figure 6 shows proper wiring.
Securitron also manufactures a line of push buttons with integrated timers (EEB2 and
EEB3N). These are easier to use with the XMS to satisfy the code requirements for access
controlled egress doors. Figure 7 shows wiring with the integrated push button/timers.
