Notification Appliance Circuits
The MPC-6000 control unit has four 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. 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-6000 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.
