4.3 LATCH STATUS SENSING
The Mortise UnLatch includes a latch status sensing feature. When the
door is closed and the door latch has engaged the Mortise UnLatch
(specifically the springlatch plunger has been pushed in by the door
latch), the Mortise UnLatch will report this secure condition by
outputting a closed circuit condition between the white (COM) and green
wires (see the drawing to the right). When the door is not securely
latched, the closure will be between the white and blue wires. This dry SPDT output can carry
1 Amp @ 30 VDC maximum. This signal is normally connected to the building alarm system
and it provides superior information compared to conventional door contacts which show only
that the door is closed, not whether it is latched. Note that the Mortise UnLatch’s ability to
report on the latched status of the door depends on it receiving constant power. Any time
power is cut to the Mortise UnLatch, it will report the door as secure regardless of whether it is
latched or not.
The Mortise UnLatch uses the information as to whether the door is latched or not for a second
purpose. The Mortise UnLatch will not operate unless the latch is in the secure position
(the springlatch plunger is pushed in). Operationally, the door can be opened anyway (it is not
latched) so there is no benefit to the end user from the Mortise UnLatch operating unless the
door is latched. Inhibiting operation when the door is not properly closed and latched also helps
protect the Mortise UnLatch against operating its motor into some jam condition in the event of
severe misalignment of the door.
