EV-AD2-EXT is a dedicated address programmer designed for marine fire detectors of EV series. It is used to program, modify and read the communication loop address of smoke and heat detectors on board ships.
Equipped with a digital address display and independent adjustment buttons of +1, +10 and +100, this programmer allows flexible and accurate address setting. Multiple indicator lights including Power, OK and ERR clearly display working status, normal communication or wiring faults in real time.
This address programmer matches the standard mounting base of EV fire detectors perfectly, featuring simple operation, compact structure and stable performance. It is widely applied in commissioning, maintenance and troubleshooting work for marine fire alarm systems on cargo ships, container vessels and passenger ships.
