The Nittan EV-PH (part no. F20-82400) is an analogue addressable combined optical smoke and heat multisensor detector for Nittan Evolution systems.A Nittan-designed algorithm reads both sensors at the same time and can raise an alarm from either or both of them. This makes the detector less prone to false alarms than single-sensor devices. Nittan now lists the EV-PYH as its backward-compatible replacement for the EV-PH.Key features Optical smoke and 54°C (A1R) heat sensors in one housing Evolution FSK protocol EEPROM addressed with a programmer Remote indicator (RIL) and base control outputs Omniview 360° LED Technical specifications Operating voltage: 20 to 35 V DC Quiescent current: 200 µA Alarm current (LED on): 5.2 mA Standards: EN 54-5:2017/A1:2018, EN 54-7:2018, CEA 4021:2003 Part number: F20-82400 Show more
