The MR-2644 LCDAnnunciator allows you to monitor and control compatible Fire Alarm Control Panels from anywhere within your facility. Up to eight MR-2644's, each set to a unique userprogrammable ID, can be connected to each FACP. A single MR2644 can be as far as 9000 feet (2.7 km) from the control panel.

The MR-2644 display follows the display of the FACP to which it is connected allowing immediate action from wherever these units are installed. The on-board system hotkeys provide quick access to Lamp Test and Acknowledge functions, but require the keyswitch to be used when accessing Silence or Reset functions.

In addition to the textual LCD, the MR-2644 incorporates six system status LEDs that offer a quick overview of system status. Monitored conditions include: Alarm, Supervisory, Trouble, Monitor, AC On, and Ground Fault.

The MR-2644 connects to a MR-2100/2200, MR-2400 or MR2900 using the FACPs annunciator port. Connection between the MR-2644 and the MR-2900 requires the use of the MR2109-3 communications board in the MR-2900 in order to drive Port 3.

Available to suit most indoors installations, the MR-2644 is available in either red or grey and ships ready for flush mounting. If surface mounting is required, simply order the MR-2644SM backbox in the appropriate color.
