The Morley-IAS MI-DCMO control output module
is used with the Morley-IAS intelligent fire alarm
control panels to provide either a single alarm
circuit or a Form C relay.
The MI-DCMO can be used to operate dry
contacts for door holders, air handling unit shut
down or other similar functions. Optionally the
module can be used to supervise wiring to the
output load providing monitoring of the
external load voltage or power supply. If the
monitored voltage falls below threshold then a
fault condition will be indicated. Each MI-DCMO uses one of the ninety-nine
possible module addresses available on a loop. It responds to regular polling from the control
panel indicated by a pulsing LED, every
successful communication.
