cover mounts utilizing screws into the sub-plate (see the drawing to the right). Do not mount
the cover yet as you will want to check operation of the unit. Mounting the cover is the
final step when everything else is complete.

4. ADDITIONAL FUNCTIONS
4.1 BYPASS
As has been discussed in the previous sections, the integral keyswitch is employed to relock the
door after a delayed exit event. This occurs when the keyswitch is momentarily turned in the
clockwise direction. If the keyswitch is turned when the door is in the “normal” (secure)
condition, bypass will occur. This releases the door for immediate, authorized exit and keeps it
released for five seconds. After five seconds, the door will resecure. Note that, when automatic
relocking is selected from the Dip Switches, a keyswitch relocking signal will be ignored
(following delayed exit) but bypass can still be performed by turning the key when the system is
secure.

4.2 EXTERNAL BYPASS
Any number of external switches can trigger the bypass function
via parallel connections. The switch must be of the normally open
type which will close +V to terminal BP to activate bypass. Note that if
you want to disable use of the integral keyswitch for bypass, just
remove and tie off the wire from the integral keyswitch to terminal BP.
