Optical Smoke and Heat Detector
Part No: F20-82400

The EV-PH is a combined Optical Smoke and Heat Detector in one unit. This advanced Multi Sensor is able to combine the benefits of both optical and heat sensing technologies making it less prone to false alarms than individual sensing devices. An innovative Nittan designed algorithm reads both signals simultaneously and generates alarm signals from either (or both) sensor(s).
