MPC-6000 / MPC-7000 / RND-2 INSTALLATION, OPERATION AND MAINTENANCE MANUAL

MPC-7000 SYSTEM DESCRIPTION

The MPC-7000 is an expandable modular fire alarm control unit. It features advanced
addressable detection, programming, and memory capability. Its base configuration includes a
power supply, two X1 addressable device circuits, four/two notification circuits (NAC), serial
interface circuit, four status relays and a programming port.
The basic MPC-7000 control unit mounts in a 38" x 18" backbox with overall cover size of 38-
9/32" x 18-3/8". Operating controls and indicators are mounted on the plate with a
polycarbonate decal for identification. An 80-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-7000 main board (MPC7-MB) provides the connections for
external field wiring and connection points for optional modules. Optional boards mount on the
main board or mount on the rear of the enclosure.
The display board and controls mount on the inner-hinged plate.
All normal operation is controlled from the front of the control unit via push-button switches.
Displays are provided by an 80-character, alphanumeric, backlit LCD display and by discrete
LED indicators for major control unit functions.
The 80-character 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 backlight 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.

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 38.5 AH
sealed lead-acid batteries within code requirements for 60 hour quiescent plus 5 minutes
alarm. The cabinet will hold batteries only up to 18 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 Circuits

The MPC-7000 control unit has two addressable device circuits (expandable to three or four),
utilizing the X1 Detection Technology. Each circuit has the capacity for 252 addresses.
