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
AL-85851
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
the
push buttons and the model TM-8L timer. Figure 6 shows proper wiring.
ALCO
also manufactures a line of push buttons with integrated timers (
AL-85852
).
These are easier to use with the
AL-85851
to satisfy the code requirements for access
controlled egress doors. Figure 7 shows wiring with the integrated push button/timers.
