Typical Wiring Configurations:
The following wiring diagrams are provided as examples of various egress control configurations.
Single Magnetic Lock:
Note:
Each wiring diagram shows an MOV wired in parallel with the magnetic lock. An MOV acts to
suppress the inductive kickback generated by a lock which, if left unsuppressed, could greatly
shorten the life of the bar’s switch contacts. The MOV has no polarity, but in order to function
properly it should be spliced into the wiring as close to the lock as possible. An MOV is provided
with each EMB unit.
If a Securitron Magnalock is used in an installation, the implementation of an MOV is
NOT necessary as the Magnalock is already internally suppressed.
Double-Door/Dual Magnetic Locks:
