4 XR2500F Fire Detection Specification
4.0 GENERAL COMPONENT REQUIREMENTS
4.1. Component Enclosure
A. Component enclosures refer to, but are not limited to, annunciator housings, power supply enclosures,
terminal cabinets, control units, and other component housings. Enclosures shall be so formed and
assembled as to be sturdy and rigid. If sheet steel is used in the fabrication of enclosures, it shall not be
less than 18-gauge door and 20-gauge box frame.
B. The FACP enclosure shall be Red and shall be designed to be surface mounted or flush mounted between
sixteen-inch on-center studs. The FACP enclosure shall be fabricated of 16-gauge cold rolled steel.
4.2 Electronic Components
A. All system electronic components shall be solid-state type, mounted on printed circuit boards or
electromechanical. Light duty relays and similar switching devices shall be solid-state type or
electromechanical.
B. The panel shall have an over current notification LED that lights when devices connected to the Keypad
Bus and Digital SLC Loop draw more current than the panel is rated for. When the over current LED
lights, the Digital SLC Loop and Keypad bus are shut down.
4.3 Control Unit
A. The Fire Alarm Control Panel (FACP) shall be the DMP XR2500F Addressable Fire Alarm Control Panel.
The FACP shall be capable of operating and supervising notification appliance devices as well as
addressable initiating detection devices and an integrated supervised dual line digital communicator.
B. The control unit shall be completely programmable remotely using Remote Annunciators, and/ or using
upload/ download software that communicates using SDLC 300 baud, 2400 baud, 9600 baud, or IP
addressed data network. On-site programming from a personal computer shall also be permitted.
Programming changes shall comply with NFPA 72 for acceptance or re-acceptance testing.
C. A battery test shall be automatically performed to test the integrity of the standby battery. The test
shall disconnect the standby battery from the charging circuit and place a load on the battery. This test
shall be performed no more than every 180 seconds.
D. The FACP shall be equipped with an anti-reversing circuit breaker to prevent damage due to accidental
reversal of battery leads.
E. The control unit shall be capable of operating and supervising notification appliance devices as well as
addressable initiating detection devices and an integrated supervised dual line digital communicator.
F. Control unit must be “Flash ROM” updatable, and program must be held in non-volatile memory. The
panel shall be able to function while the update is in process.
G. Control unit shall be capable of operating using an optional built in Encrypted Alarm Router for SCIF
(Sensitive Compartmented Information Facility) applications that is certified by NIST (National Institute
of Standards and Technology) for 128 Bit AES Rijndael Encryption communications.
4.4 User Authorization
The system shall be capable of operation by 10,000 unique passcodes, with each passcode having one of 99
authority levels. This allows for the limitation of certain functions to authorized users. The operation of all
annunciators shall be limited to authorized users by this code or by a key.
4.5 Annunciation Lamps/LEDs
Visual Annunciators used on Annunciator modules and elsewhere throughout the system shall be either
electric lamps or light emitting diodes (LEDs, LCDs or VFDs). Annunciators shall be so connected in the
circuit that Annunciator failure, socket or protective circuitry shall not result in an improper or
indeterminate signal. Lamps of varying types, voltage, and wattage shall have bases and sockets that
prevent incorrect replacement.
