VIEW™ Very Intelligent Early Warning HSSD Detector
Data Sheet
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.
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.
Features
• Alternative to Aspiration Systems
• Advanced laser light source and patented optical design
• Sleek low profile design
• Analogue addressable communications
• Stable communication technique with high noise immunity
• Pre-Alarm sensitivity to 0.07%/m & alarm sensitivity to 0.1%/m
• Low standby current
• Rotary decade 01 to 99 address switches
• Dual LED design provides 360° viewing angle.
• Visible two-colour LEDs blink green when the sensor is
addressed (optional), steady red for alarm
• Built-in functional test switch activated by external magnet
• Optional relay, isolator, or sounder bases
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)
