Notification Appliance Circuits
The MPC-7000 control unit has four (expandable to twelve) independent Class B (Style Y)
notification appliance circuits (NACs). Pairs of NACs can be combined for Class A (Style Z)
operation. This reduces the number of NACs to two (six). Each circuit can be selected to give
continuous output or one of eight sounding patterns available in the control unit including the
Faraday SYNC Protocol. There is also a system coder capable of zone-coded operation. All of
the NACs are power limited.
Serial Interface Circuit
The MPC-7000 control unit has a Serial Interface Circuit that will drive up to 16 remote LCD
annunciators and 8 Serial Relay Units and Serial Annunciator Units.
Status Relays
Four relays with dry contacts are provided. These relays are programmable to power fail,
alarm, trouble and supervisory functions. The relay contacts are Form C and are rated 1A @
28VDC resistive
Programming Port
An RJ-11 jack is provided for a non-isolated RS-232 connection for temporary connection to a
computer for panel programming.
