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 five sounding patterns. There is also a system coder capable of
zone-coded operation. All of the NACs are power limited and support synchronization of listed
devices via the Faraday SYNC Protocol.
Serial Interface Circuit
The MPC-7000 control unit has a Serial Interface Circuit that will drive up to 16 remote LCD
annunciators and up to a total of 8 Serial Relay Units and Serial Annunciator Units.
Status Relays
Four relays with dry contacts are provided. Three relays are programmable and the Trouble
status relay is non-programmable. The relay contacts are Form C and are rated for 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.
