Fire-Lite MS-5UD Control Panel

The MS-5UD is fully programmable via built-in keypad and 80
character LCD display, so you do not need an external programmer.
Both panels have a built-in Digital Alarm Communicator Transmitter
(DACT) and availability to add optional equipment: Remote
annunciator, Relay module, LED Driver module, transmitter module
and printer interface module
The Notification Appliance Circuit (NAC) protocol includes the ability
to silence audible devices while strobes continue to flash, using only
a single pair of wires, as well as automatic synchronization for five
manufacturer’s synchronization protocols of audio/visual devices.
