Combining two methods for detecting fire into one unit, the advanced multi-sensor combines the benefits of dual optical and heat sensing technologies. This means that the Nittan EV-DPH-A2R Dual Optical and Heat Detector is less prone to false alarms than individual sensing devices.

Using innovative technology, the low-profile detector analyses particle size to differentiate between smoke, steam, dust and aerosols. Featuring Infra-Red and blue LEDs, the angled sensor which only receives the light when reflected off smoke entering the chamber which then activates the alarm. This gives more reliable detection which is suitable for areas of multiple occupancies like hotels, flats and hospitals.

The dual optical smoke sensor uses drift compensation and a grey-coloured chamber to prevent dust and other slow environmental changes affecting its performance. The A2R rate-of-rise heat sensor activates when temperatures increase quickly, and the unit comprises a sensor self-test feature.

The 360°, Omni-view LED, shown in the picture as the red ring, shows when the alarm is activated or flashes to show it is communicating with the control panel, although this is controllable.

The low-profile detector can be installed in any orientation using a detector base (available separately). The EV-DPH-A2R detector is compatible with Nittan and Nittan protocol systems and will need addressing with a handheld programming tool.

For a dual optical and heat detector which activates when temperatures reach a higher, pre-set temperature, look at the Nittan EV-DPH-CS Heat Detector.
