the generic fail safe lock, initiate device and reset device.

Figure 11 shows general wiring when the bypass input is used. This is typically because either
the LCP is using momentary switches or the local release switch is momentary. The bypass
input will release the lock without signalling any alarm for 5 seconds. Use of the bypass input
makes substantial changes in the entire wiring scheme. The lock status or door status switch
no longer reports directly to the panel but rather reports to the XDT board lock status input. The
reason for this is to avoid causing the panel to alarm when bypass is used for legal release.
The XDT's lock status monitoring function will continue to report secure to the panel when any
board function has released the lock and for 5 seconds after it has resecured the lock. This
delay permits a door to complete closing and allows the lock time to "pull in" before an alarm
condition is created.
One particular note is that if you employ the
KP1 or MK1 switch bypass option
, you will not
bypass the toggles. Use of the toggle will still send power out of the E terminal and from there
to the BP terminal on the XDT board which will release the lock. Do
not use this option
with
delayed exit.
