Nittan EV-PYH Photoelectric Optical amp Heat Multi-Sensor
Nittan EV-PYH Photoelectric Optical Heat Multi-SensorThe EV-PYH is an Optical SmokeHeat Detector that comes tothe market with some exciting new technological advances centred on an enhancednew PY smoke sensing chamber.The EV-PYH is designed as a backward compatible replacementfor the EV-PH and fully compatible with Evolution analogue addressable systems.The sensor includes a spherical feature within the smokechamber providing unrivalled performance for scattering light plus an OrangeLED which significantly improves response across the fire spectrum. TheChamber construction is designed to minimise the effect of dirtdustcontamination with a fine micromesh made of stainless steel to prevent ingressof even the smallest insects which can create false alarms.This advanced Multi Sensor is able to combine the benefitsof both optical and heat sensing technologies making it less prone to falsealarms than individual sensing devices. An innovative Nittan designed algorithmreads both signals simultaneously and generates alarm signals from either orboth sensors. The Heat sensor is Category A1R.Key FeaturesOrange Optic LED and PY Type Chamber3 Sensitivity SettingsHeat Category A1RBackward compatible with EV-PHDrift compensationEvolution FSK protocolEEPROM Addressed with programmer
