The Nittan EV-DPH-A2R (part no. F14-82106) is an analogue addressable dual optical smoke and heat multisensor for Nittan Evolution fire alarm systems. Its heat element is class A2R to EN 54-5.
It combines Nittan's dual optical smoke sensing (two LEDs) with a heat sensor, which Nittan says reduces false alarms. It uses the Evolution FSK protocol, is EEPROM addressed with a programmer and has remote indicator (RIL) and base control outputs.
