Vanderbilt ACTpro-120 - Break Glass Monitoring Only

3.7 Break Glass monitoring only
The break glass monitoring features only monitors the break glass status and does not remove power from
the lock. Vanderbilt assumes a double pole break glass unit is used, one pole to disrupt the power to the
lock the second pole for monitoring.
When the break glass is not activated the B/GL input pin is held low at 0V. When the break glass device is
activated the B/GL input pin will lose the 0V (goes high) and report a break glass event. The lock should be
wired such that when the break glass is activated power to the lock is removed.
