Description
The DP951B 950 Series Addressable Optical Sensor is a black 950 series, elegant slim-line analogue addressable optical sensor with high performance analogue addressable smoke detection features. It is also available with French approval (as the DP951-F), and in black in stead of the normal white colour (DP951B).
950 Series Optical Detectors
An internal pulsing LED and a photo-diode at an obtuse angle checks for smoke entering the chamber. The light pulse from the LED is scattered and registered by the photo-diode. The scattered light is measured and transmitted to the fire panel. The DP951B 950 Series Addressable Optical Sensor (Black) are additionally available in black for false ceiling applications.
Unique Addressing
A unique, patented addressing method provides simple, user-friendly and accurate identification of device location, available both in standard and black bases. A coded card, inserted in the base, is read by the detector as it is plugged in. All the electronic components are in the detector, but the location information is held in the base. Addressing errors during maintenance are eliminated because the address remains in the base. Pre-coded and pre-numbered address cards are available. |
