MR-2900 Installation Manual 1.0 Technical Information 1.1 General The MR-2900 Fire Alarm Control Unit provides capability for up to 24 Input Circuits, 8 Polarity Reversing Bell Circuits, network capabilities (with use of an MR-2910 Network Board) and 4 General Purpose Form "C" Relays as well as system operated relays for alarm, trouble and supervisory indication. If the MR-2900 is ordered with a printer, it is ordered under the panel number MR-2920.
Communication Ports The Control Unit has 6 communication ports available: • • • • • • Port #1- network (Proprietary) Port #2- network (Proprietary) Port #3- general purpose (Proprietary) Port #4- service terminal (RS232 - DB9) Port #5- printer interface, Parallel (IBM/Centronics - DB25) Port #6- serial printer interface (RS-232) Ports 1 to 3 use the terminal strip on the Terminal Board for connection. Ports 4 and 5 use the connectors mounted on the bottom of the Main Circuit Board.
MR-2900 Installation Manual 1.3 Front Panel The system controls consist of 12 system switches and a 20 position alphanumeric keypad. The 12 system switches are factory defined for operations such as alarm acknowledge, signal silence and system reset. The 20-position keypad is used for: • • • • • technical functions system/detector maintenance history recall device/circuit disarming manual operation of addressable output modules, relay modules and bell circuits 1.
Addressable Input Circuits There are two classes of addressable input circuits supported by the Control Unit: • • "Class A" (Style 6) - This is a 4 wire circuit supporting addressable detectors and modules. It requires two input circuits, one for signal out and one for signal return. Up to 99 detectors and up to 99 modules can be connected to the circuit. "Class B" (Style 4) - This is a 2 wire circuit supporting addressable detectors and modules.
MR-2900 Installation Manual 1.6 Terminal Board Field connections are terminated on the MR-2936 Terminal Board, which in addition to terminal blocks contains a portion of the circuitry for output circuits and relays. The Terminal Board includes connections for 24 input circuits, 8 supervised polarity reversing bell circuits, 4 general purpose Form "C" relays, 3 system Form "C" relays and 2 auxiliary power outputs.
1.8 Power Supply The Power Supply (MR-2905) is rated at 8A unregulated, providing the system with primary DC power. It is complete with a battery charger rated at 2 A and battery supervision circuitry. The power supply and battery are located within the control unit back box. Battery supervision uses true dynamic supervision circuitry to simulate 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.
MR-2900 Installation Manual For NFAPA Style 7 connection of the network, port 1 of node 1 is connected to port 2 of node 2. Port 1 of node 2 is connected to port 2 of node 3. Port 1 of node 3 is connected to port 2 of node 4. Therefore, in general, port 1 of node N is connected to port 2 of node N+1. The last node of the network is handled differently. For example, assume the system has a total of 30 nodes. In this case, the last node of the system is node 30.

5.0 Appendix A: Power Supply and Battery Calculations IMPORTANT NOTICE The main AC branch circuit connection for Fire Alarm Control Panel must provide a dedicated continuous power without provision of any disconnect devices. Use #12 AWG wire with 600-volt insulation and proper over-current circuit protection that complies with the local codes. Refer to 3.0 Technical Specifications on page 23 for specifications.
MR-2900 Installation Manual 5.1 General Batteries are designed and manufactured for a specific use. "Standby" is one of these uses. They are rated according to their ability to deliver a steady current for 20 hours ("20 Hour Rating"). A 10 Ah battery is unable to deliver 10 A for 1 hour, however it does deliver 2 A (500 mA) for 20 hours. A car battery is designed to deliver "cranking" power for a short time, (a few hundred Amps for a few minutes).
