I. INTRODUCTION
CONTROL UNIT LIMITATIONS
This control unit may not show an alarm condition without compatible initiating devices (smoke detectors,
etc.) and notification devices (horn, lights, etc.) connected to it. Electrical ratings of the initiation and
notification appliances must be compatible with the electrical ratings of the control unit and must be
properly interconnected. The wiring used for interconnection must be large enough to carry the total
current for all appliances without excessive voltage drop.
The control unit must be connected to a dedicated primary electrical source that has a high degree of
reliability and adequate capacity for this control unit. The only means of disconnecting this power source
shall be available only to authorized personnel and clearly marked "Fire Alarm Circuit Control".
The control unit must also have connected to it a battery set (24v) that has enough capacity to properly
operate the system for 24 or 60 (depending on system type) hours standby and 5 minutes alarm per
NFPA 72 (chapter 1). These batteries do lose capacity with age. Batteries must be replaced when they
fail to provide the control unit with the required standby and alarm power or after 4 years, whichever
happens first. These batteries must be checked for performance at least two (2) times a year or more
often if local requirements dictate.
Fire alarm control units cannot last forever. Even though this control unit was made to last for the
expected life of the fire alarm system, any part could fail at any time. Therefore a regular test program
should be followed and documented to make sure that each part of the system is tested as in Chapter 7
of NFPA 72 or more often if dictated by local code requirements. Malfunctioning units must be replaced
or repaired immediately by factory authorized service personnel.
NOTE: This control unit is designed to show an alarm condition when the
initiating devices connected to it detect specific conditions. These conditions
may or may not represent a life-threatening condition. Also, evacuation of a
building or area unnecessarily may subject individuals to an unnecessary
hazard. Therefore, it is most important that the building owner, manager, or
representative promulgate, distribute, and/or post instructions describing
steps to be taken when the fire alarm control unit signals an alarm condition.
These instructions should be developed in cooperation and conformance with
representatives of the local authority having jurisdiction.
As a backup or precautionary measure, it is strongly suggested that one of these steps should be to notify
the local fire department of an abnormal condition even where the DACT option (or similar device) is
included in the system.

12530/12540 OWNER'S MANUAL
P/N 447203 Issue I II-5
ADDRESSABLE DEVICES
Faraday Addressable Detectors
The control unit processor sends the sensitivity and pre-alarm settings to the detectors and polls the
detectors as to their status. The detector determines normal, trouble, pre-alarm or alarm conditions and
relays the status to the control unit.
Variable Thresholds
The obscuration level for alarm can be adjusted from the control unit on a permanent or time-variable
basis. This facility also means that the control unit can display information on individual points for
maintenance or service.
Operator Alerts
The control unit can trigger an alarm or trouble automatically on the occurrence of a number of conditions
of the detector. These include:
•Maintenance alert
•Pre-alarm alert
•No response
•Incorrect response
Other Faraday Addressable Devices
Heat Detectors
Addressable heat sensing detectors may be intermixed on the circuit for locations where heat sensing
may be the most effective detection mode. The heat detectors may be programmed, through the control
unit, for rate of rise operation.
Addressable Modules (Monitor and Control)
In addition to detectors, the circuit can communicate with addressable modules, allowing initiating devices
or notification appliances with local power sources, and supervising the power sources.
Manual Stations
Addressable manual stations may be intermixed on the circuit with proper response programmed into the
control unit.
System Sensor Addressable/Analog Sensors
Since an analog fire sensor is essentially a transducer rather than a warning device, all of the operating
controls are included in the control unit processor program. The control unit interprets the pulse widths
from the sensor and determines normal, trouble or alarm conditions.
Variable Thresholds
The obscuration level for alarm can be adjusted from the control unit on a permanent or time-variable
basis. This facility also means that the control unit can display information on individual points for
maintenance or service. These displays include:

12530/12540 OWNER'S MANUAL
P/N 447203 Issue I II-6
•Status
•Current % obscuration for smoke sensors
Operator Alerts
The control unit can trigger an alarm or trouble automatically on the occurrence of a number of conditions
of the sensor devices. These include:
•Maintenance alert
•Pre-alarm alert
•No response
•Incorrect response
Other System Sensor Addressable Devices
Heat Sensors
Compatible heat sensing addressable devices may be intermixed on the circuit for locations where heat
sensing may be the most effective detection mode.
Addressable Modules (Monitor and Control)
In addition to sensors, the circuit can communicate with addressable modules, allowing initiating devices
or notification appliances with local power sources, and supervising the power sources.
Manual Stations
Single and dual-stage manual stations with monitor modules may be intermixed on the circuit with proper
response programmed into the control unit. For fastest response, manual stations should be connected
so that their address is 1-9.
PROCESSOR CONTROLLED OUTPUT ZONES
While the notification appliance circuits are essentially hardware circuits, the fact that the outputs are
commanded and controlled by the processor does provide more versatility than in a total hardware
system. All functional selections are included in the control unit programming process.
Output Sounding Patterns
The notification appliance circuits are operable in different sounding patterns. Any circuit is selectable to
any of eight software-generated patterns or continuous sounding. For convenience, three of the patterns
are preprogrammed for March Time, Temporal, and Californian patterns.
Control of Audible Silencing
It is possible to select an “auto-silence” mode, adjustable from 0 to 255 minutes. Each notification
appliance circuit programmed for alarm silence sequence, will be silenced upon time-out of the auto-
silence timer. The alarm silenced LED will flash, indicating the auto-silence time-out.
Audible Silence Inhibit
In addition to designation of waterflow zones, the entire control unit may be programmed to inhibit audible
silence for 0, 1, 3, or 6 minutes from the last alarm. System reset may also be inhibited.

EVENT HISTORY
The control unit includes a non-volatile memory recording up to 2000 system events. Identified alarm,
trouble, supervisory trouble, and other significant events will be recorded along with the date and time of
occurrence, and can be inspected by operating front panel push buttons.
Events recorded in the history are:
•Alarm, Trouble, or Supervisory conditions.
•Drill, Tornado, Recall and General Alarm.
•Activation of NACs or modules used for sounders or strobes.
•Unit used for command functions. (Silence, acknowledge, reset, etc.)
•PAS_INHIBIT switch activation.

GENERAL DESIGN FEATURES
Environmental
All hardware is suitable for use in an interior or protected location.
Power Limiting
The city tie circuitry is not power limited when programmed for Local Energy or Shunt operation. The AC
power and battery wiring are not power limited. All other circuits leaving the control unit are power limited,
provided the proper installation rules are maintained.
Ground Fault Detection
The control unit provides ground fault detection and a ground fault will trigger the common fault buzzer
and system trouble LED. There are separate LEDs on the main termination board to indicate positive and
negative ground faults.
Transient Protection
Transient protection devices are provided where needed to meet the requirements of UL864.
Security Functions
Processor control and addressing allow inclusion of several functions to assure security of the system.
Multi-level password protection of programming functions prevents unauthorized configuration changes.
Device type supervision: If the type reported by an addressable sensor or module, does not agree with
the configuration, the system reports a trouble.
Device address supervision: The system checks that all configured devices on the addressable device
circuit responds to an address poll. If a configured device is missing, the system reports a trouble. The
system also polls unused addresses periodically. If a device responds to such a poll of a non-configured
device, the system reports a trouble. Two devices addressed the same also cause a trouble to be
reported.
The RS485 devices also are checked for no response and un-programmed address responses.
REGULATORY STANDARDS
The 12530/12540 control unit meets the requirements of industry and government regulatory agencies as
noted.
Underwriters Laboratories
The 12530/12540 Fire Alarm control unit is listed under UL Standard 864 for compliance to NFPA
Standard 72 for fire service
