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, MR2622, 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-2644 and/or a MR-2614 series annunciator for remote control and display. The MR-2644 is an LCD only display with controls. The MR-2614 can contain up to 72 zones (216 LEDs) for annunciation and four pre-deﬁned switch inputs for control functions. The MR-2644 and MR2614 connect to the annunciator port on the MR-2400.

Main Control Unit System controls and visual indicators are contained on the main circuit board which also contains the system processor, programming port, printer port and non-volatile memory for storage of system programming. Operating software is installed on the main board for critical functions such as timing functions and non-critical functions such as custom zone and devices messages. The scroll button located next to the display is used to scroll through the display. It is available without having to open the cabinet. Once the entire list has been shown, pressing the scroll button again will show the beginning of the list. The keypad can also be used to scroll through the display. The keypad and the display are also used for maintenance functions, such as testing. Addressable devices are indicated on the LCD display which provides device number, addressable input circuit number and custom message.

Hot Keys Display The visual display consists of a series of LEDs for common system indication of power, alarm, supervisory, and trouble. ALARM The notiﬁcation appliance (bell) circuits, Style Y and Style Z, are rated at 1.0A @ 24VDC. (Note : maximum system loading and stand-by battery power must be considered when determining actual notiﬁcation appliance (bell) loading). Style Y (Class B) notiﬁcation appliance (bell) circuits require a 10kΩ end-of-line resistor for supervision. The general purpose Form C relay operation is program deﬁned. The relays are rated at 1.0A @ 30VDC. The system Form C relays are for common alarm and trouble indication. These relays are rated at 1.0A @ 30VDC. TROUBLE SUPERVISORY AC POWER System Display An 80 character (4 x 20) supertwist backlit LCD alphanumeric display is provided for identiﬁcation of addressable devices and input circuits, and for display of history ﬁles, ﬁrst/last device in alarm, custom messages, etc. Custom alphanumeric messages can be assigned on a per device basis for addressable devices.

Issue 1 Commmunication Ports Enclosure The following ports are available for use : The enclosure for MR-2400 consists of a back box complete with power supply, and an inner assembly complete with main board, and door assembly. The back box and door assemblies are fabricated from 1.59mm (1¼16”) steel. The front door includes a tempered glass window, hinge, and lock assembly. The back box provides knock outs for conduit entry. The enclosure dimensions are 36.83cm wide x 52.07cm high x 10.16cm deep (14.5 x 20.5 x 4in). The front door assembly is 38.10cm wide x 53.34cm high x 1.27cm deep (15 x 21 x 0.5in). Port #3 - general purpose (RS-232/opto-coupled/RS-485) Port #4 - service terminal (RS-232) Port #5 - printer interface (IBM/Centronics) Port #6 - annunciator port (proprietary) The system service terminal port (RS-232) permits the downloading and uploading of custom software such as device messages and I/O functions. This port is a DB-9 connector behind the terminal strip. BACK BOX The system printer port is a parallel port (IBM/Centronics) providing an interface to any standard printer. It can be used for system commissioning and testing by producing a printed log of received events. This can then be checked against a log of tests performed to conﬁrm correct operation. This port is a DB-25 connector behind the terminal strip. The system general purpose port is available for remote annunciation of system alarm and system trouble. The operation of this port is software deﬁned and requires the use of an MR-2109-X board. This port is on the terminal strip. An MR-2109-2 board is used for communications to the MR-2944 annunciator or to an SE2000. An MR-2109-4 is used for communications to GRID or MV-2700. This port can only be used for one purpose at a time. Each different use of the port requires a different operating program in the MR-2400. The annunciator port is used for connection to MR-2644 and/or MR-2614 annunciators. This port is located on the terminal strip. Power Supply The MR-2905 power supply is rated at 10A unregulated, providing the system with primary DC power. The power supply is complete with battery charger rated at 2A and battery supervisory circuitry. The power supply is located in a separate compartment behind the main board. POWER SUPPLY BOARD 120 VAC COMPARTMENT MAIN BOARD TOROID TERMINAL STRIP BATTERIES Exploded View of MR-2400 Field Programming The system program can be downloaded, in the ﬁeld, from a computer via the service terminal port. The control unit operational database is downloaded from a computer. There is provision for uploading the database from the control unit to the computer. All information is stored in non-volatile ﬂash memory and E2PROM. AC GROUND PLUG FOR TERMINAL BOARD G N L PLUG FOR BATTERY PLUG FOR TRANSFORMER Battery supervision uses true dynamic supervision circuitry, simulating a load condition approximately every 90 seconds to ensure that the battery is capable of handling the system load requirements on loss of primary power. A second compartment behind the main board is provided for 120VAC or 220VAC terminations. Issue 1 SECUTRON INC. Catalog Number 1004 Not to be used for installation purposes.
