DESCRIPTIONS
MPC-6000 SYSTEM DESCRIPTION
The MPC-6000 is a modular fire alarm control unit. It features advanced addressable
detection, programming, and memory capability. Its base configuration includes a power
supply, an X1 addressable device circuit, four/two notification circuits (NAC), serial interface
circuit, four status relays and a programming port.
The MPC-6000 control unit mounts in a 22" x 18" backbox with overall cover size of 22-9/32" x
18-3/8". Operating controls and indicators are mounted on the inside hinged plate. An 80
(4x20) – alphanumeric character LCD provides specific indications for addressable devices
while LEDs indicate general panel status.
Semi-flush mounting kits are available for the enclosure.
The main board mounts in the rear of the enclosure. The power supply is physically contiguous
with the main board. The MPC-6000 main board (MPC6-MB or MPC6-MB2) provides the
connections for external field wiring. Optional boards mount on the main board or on the rear
of the enclosure.
The display board (MPC6-DB or MPC6-DB2) mounts on the inner-hinged plate.
All normal operation is controlled via a membrane keypad. Displays are provided by an 80-
character, alphanumeric, backlit LCD display and by discrete LED indicators for major control
unit functions.
The 80-character (20 x 4) LCD is used to display event data, including alarms and troubles,
identification of zone or device, and presentation of history. The display is controlled by a set of
four push-button switches commanding the control processor. A back light is included in the
display to assure visibility in low light, but to conserve power it is only activated during a
reported event or on operation of a display control switch.
Individual LEDs on the panel are provided to indicate SYSTEM ALARM, PREALARM,
SUPERVISORY, ALARM SILENCED, SYSTEM TROUBLE and AC POWER ON. Direct push-
button controls are provided for ALARM SILENCE, ACKNOWLEDGE, MENU and SYSTEM
RESET. For MPC-6000 Electronics Package2, LEDs for Releasing application
(PREDISCHARGE, ABORT, DISCHARGE) are also provided.
Power Supply
A 24V (nominal) power supply provides all operating power to the control unit for both standby
and alarm conditions. Sufficient battery charging capability is available to charge 38 AH sealed
lead-acid batteries within code requirements for up to 90 hours quiescent plus 5 minutes
alarm. The cabinet will hold batteries only up to 12 AH. The back-up battery is 24V, maintained
by floating on the power supply. The battery will be automatically disconnected at low battery
voltage to prevent deep discharge.
X1 Addressable Device Circuit
The MPC-6000 control unit has one addressable device circuit utilizing the X1 Detection
Technology. The circuit has the capacity for 252 addresses.
