ALO-V Intelligent Analog Photoelectric Smoke Sensor-Asian-technologies-ltd
STANDARD FEATURES
• UL 268 7th Edition Listed
• Designed to resist unwanted alarms from cooking
and other nuisance alarm sources
• Optical particulate identification
• Early fire smoke detection
• 360° view of detector status LED
• Programmable non-polling LED
• Vandal resistant security locking feature
APPLICATION
The ALO-V (UL 268 7th edition listed) is a reliable, high quality multi-criteria Photoelectric Smoke Detector. It can be used
in all open areas where Photoelectric Smoke Detectors are
required. This detector is also suitable for monitoring smoke in
HVAC ducts. The newly developed “multi-spectrum smoke
categorization technology” detects smoldering and flaming
fires fueled by traditional materials and polyurethane while
reducing nuisance alarms.
The ASB7, ASBL7, SCI-B47, SCI-B67, YBN-NSA-47, and
HSB-NSA-67 bases are UL Listed with the ALO-V.
OPERATION
The construction of the new chamber enhances the smoke
entry for early fire smoke detection. The detection chamber
utilizes light from IR and Blue LED sources. In the event of
fire, particles of smoke enter the chamber and scatter light in
proportion to the smoke density, resulting in an increased
analog smoke measurement. The chamber contains a unique
baffle design which allows smoke to enter the chamber while
preventing external light from affecting the photodiode detector.
When the smoke density exceeds the programmed sensitivity
threshold, the detector transmits an interrupt to the fire alarm
control panel indicating a fire condition. The fire alarm control
panel automatically adjusts the detector threshold to compensate for contamination.
Up to 127 devices are permitted on each SLC loop. The detector address is set by using a model AP7 hand-held programmer. The detector can mount to a variety of bases including electronics-free 4 and 6 inch bases, relay bases, and
sounder bases. The detector’s status LED is viewable on the
main face of the detector from all directions.
DETECTOR SPACING
Smoke detector spacing shall be in compliance with NFPA 72.
For smooth ceilings and in the absence of specific performance-based design criteria, the distance between smoke
detectors shall not exceed a nominal spacing of 30 ft. (9.1m)
or all points on the ceiling shall have a detector within a distance equal to or less than 0.7 times the nominal 30 ft. (9.1m)
spacing. Detectors shall be located within a distance of onehalf the nominal spacing, measured at right angles from all
walls or partitions extending upward to within the top 15 percent of the ceiling height. For additional instructions see NFPA 72.

The Hochiki SPC-24 Projected Beam Smoke Detector consists of an emitter and receiver. The SPC-24 detector should be placed so that smoke generated by a fire will likely rise into the path of the beam. The receiver is constantly monitoring and measuring the intensity of the beam transmitted by the emitter. Should the smoke from a fire cause a decrease in the signal strength of a magnitude that exceeds the programmed obscuration setting, an alarm signal is generated.
