Description of Operation
Connection of Guard Locking
Control
With two-channel control, the jumper between IMP1 and IMP2 must be
removed. Connection as shown above.
Dual-Channel
Solenoid Control
Hardware Rev B provides the possibility of a dual lock command. Rev B
models have three possibilities for solenoid control of the 442G-MAB:
a. 1-channel IMP1 (+24VDC) with jumper
b. 2-channel IMP1 (+24VDC) and IMP2 (+24VDC)
c. 2-channel IMP1 (+24VDC) and IMM (0V)
The factory-default setting for Rev B models is for single-channel control (a
jumper installed in the base of the lock module connects IMP1 and IMP2).
