The MR-2400 fire alarm system control unit is the heart of a  sophisticated microprocessor-based fire alarm system. Employing addressable input circuits with addressable analog detectors, and monitoring and control modules, the MR-2400 is ideally suited to  fit the varied needs of residential, commercial, industrial, and  institutional applications.

 The MR-2400 provides up to 2 Style6 (ClassA) addressable or 4 Style4 (ClassB) addressable circuits, 2 general purpose FormC relays and 6 polarity reversing notification appliance (bell) circuits as well as system operated relays for alarm and trouble indication.

The MR-2400 can use a MR-2944 series annunciator for remote  control and display. The MR-2944 can contain up to 576 LEDs  (192 zones) for annunciation, an LCD display for messages, and 16 pre-defined switch inputs for control functions. The MR-2944  can use any of the MR-2902, MR-2622, or MR-2915 boards for  interfacing to the LEDs. Using the MR-2944 requires that the  MR-2400 have the MR-2109-2 communications module installed.

The MR-2400 can use a MR-2614 series annunciator for remote  control and display. The MR-2614 can contain up to 216 LEDs  (72 zones) for annunciation and 4 pre-defined switch inputs for  control functions. The MR-2614 can use any of the MR-2902,  MR-2622, or MR-2915 boards for interfacing to the LEDs. The  MR-2614 connects to the annunciator port on the MR-2400.
