3. Silence, Acknowledge, & Stop/Go Connections

Connecting the ACK & STOP/GO terminals of all units in a multiple-unit
system allows the operator to control and acknowledge alarms from any
unit in the system or via external switches. However, each Minimux’s

®

II

relay will operate independently, so it may be necessary to wire them in
parallel to drive a single alarm device. Also, each Minimux’s

®

II internal

horn operates independently.

Other Connections

Connections for Power, Signal Inputs, Alarm-In, and Alarm Relay are all
made the same way as for single units.
