The RE – 1504 & RE – 1508 is a 4 & 8zone microprocessor based conventional Fire Alarm Control Panel. The Panel accepts water flow devices, conventional input devices like 2 wire and 4 wire smoke detectors, Manual Call Points and other normally open contact devices. The Outputs include two notification appliance circuits (NACs), Resettable 24v D.C. output, Three Form –C relays for alarm, fault and supervisory. This panel is field programmable via the front panel keypad. It supervises all wiring, AC voltage and Battery level.

_ 4/8 Class B initiating device circuit (IDC). _ All zones accept smoke detectors and any normally open contact device. _ Any Zone can be configured as Alarm or supervisory Zone. _ 2 Class B Notification Appliance Circuits (NAC). _ Fully complies with UL -864 and NFPA-72. _ Rugged CRCA sheet with powder coated finish. _ Operates on 220v 50Hz, AC Mains power supply. _ Standby (battery) backup 24v DC power supply with built in charger _ 20x4 Dot Matrix LCD Display. _ Error free Fire / Fault status in unambiguous colored LED indication. _ System ON indication. _ Main, Standby status audible and visual indication. _ Battery Low visual warning with audible tone. _ Form–C relays for fire, fault and supervisory. _ Resettable 24v D.C.
