The combined dual detectors work together so it can reduce the likelihood of a false alarm, as well as generating alarm signals from both or either.

Using patented technology featuring Infra-Red and blue LEDs to reduce false alarms which are commonly caused by steam and aerosols. It enables the detector to calculate the particle size, and therefore whether or not is smoke. This is the ideal choice for hotels, flats, hospitals, and multiple occupancy areas.

The multi-sensor combines the benefits of both while the self-test function ensures it remains in good working order. Working with an A2R rate-of-rise heat sensor, the optical sensor has a grey chamber and drift compensation which prevents slow environmental changes, like dust, affecting its performance.

With an Omni-view indication light which is visible from 360°, this means it can be installed in any orientation, which is the red ring visible in the pictures. This shows when the alarm is activated, or flashes to show it is communicating with the control panel, although this is controllable. Needing a detector base, sold separately, the EV-DPH-A2R detector fits Nittan and Nittan protocol systems and is addressed using 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.
