The VIEW™ is an analogue, addressable, low profile high sensitivity smoke sensor designed for use with NOTIFIER intelligent fire alarm control panels.

The unique design of this sensor uses an extremely bright, tightly focused laser diode, with special lens and mirror optics, combined with enhanced AWACS™ algorithms in the NOTIFIER fire control panel, to achieve a signal‑to‑noise ratio allowing smoke detection sensitivity up to 50 times greater than traditional photoelectric technology.

In addition, the light beam and algorithms, allow the system to differentiate between dust and smoke particles. Using these algorithms, the VIEW™ system provides drift compensation, three levels of maintenance alert, selection of nine alarm levels and nine pre‑alarm levels. The system includes a self‑learn sensitivity adjustment to set the pre‑alarm level just above the peak levels sensed over extended periods for each sensor’s actual environment. Multiple sensor algorithms permit the control equipment to consider readings from up to six sensors in an area to provide faster detection of incipient fires. The AWACS™ algorithm also includes the ability to add reference sensors, such that smoke particles in the incoming air supply to an area can be compensated for, further reducing the possibility of unwanted alarm.

Using a point type analogue addressable sensor, the VIEW™ system inherently does not have transit times from sensing points to a detector, (a factor inherent in aspiration systems)

delaying the sensing of a fire condition and since it does not rely on a single sensor for the room, no dilution can occur. A point sensor also enables the control panel to provide the operator with a pinpoint description of where the fire is located rather than a room alarm.
