SYSTEM DESCRIPTION
The 12530/12540 is an advanced modular fire alarm control unit. It features addressable/analog
detection, programming, and memory capability. Its base configuration includes two addressable device
circuits, with four conventional notification appliance circuits.
The 12530 control unit mounts in a 24" x 14-3/8" back-box with overall cover size of 24-9/16" x 14-3/4".
The 12540 control unit mounts in a 35-11/16" x 14-3/8" back-box with overall cover size of 35-31/32" x
14-3/4". Operating controls and indicators are mounted on the plate with a polycarbonate decal for
identification. An 80-character LCD display provides specific indications for addressable devices while
LEDs indicate general panel status.
Semi-flush mounting kits are available for the enclosure.
HARDWARE CONFIGURATION
The main termination board mounts in the rear of the enclosure. The power supply is physically
contiguous with the main board. The 12530/12540 main termination board provides the interface for
external analog system connections, for the addressable device circuit, four notification appliance circuits,
remote signaling and indicating interfaces, and the electronics of the main system power supply. Optional
boards mount on or plug into the main termination board.
The main logic board mounts on the front plate, allowing it to carry the controls and displays which must
be accessible.
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 display 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, TROUBLE SILENCE/ACKNOWLEDGE, MENU and SYSTEM RESET. These
switches require concurrent use of the security keyswitch.
