Where do you put a beam detector?
The beam detector can be mounted with the transmitter/receiver on one wall and the reflector on the opposite wall, or both suspended from the ceiling, or any wall/ceiling combination. In the case of the ceiling mount, the distance from the end walls should not exceed one-quarter of the selected spacing (7.5 ft.
What is an OSID detector?
The OSID system detects smoke by measuring the attenuation of two wavelengths of light projected from one or more locations within an area of protection. Each OSID system consists of one Imager and up to seven Emitters within the protected area. The Emitters are placed in the field of view of the Imager.
How do beam smoke detectors work?
Beam smoke detectors operate on the principle of obscuration. As a smoke field develops, the detector senses the cumulative obscuration – the per- centage of light blockage created by a combination of smoke density and the linear distance of the smoke field across the projected light beam.
How do you test a fire alarm with a beam detector?
Lay the “Alarm” test filter section over the receiver lens. The alarm should sound within 15 seconds. If the detector does not alarm, check and correct the wiring, then test the unit again. If the alarm does not go off after the second test, return the beam detector for repair.
How do you clean a beam detector?
A Compensation Fault can be cleared by cleaning the Reflector and Detector lenses using a dry lint-free cloth, and then re- aligning the beam. Compensation Faults can be avoided by periodic cleaning of the Reflector and Detector before compensation limit is reached.
What is OSID number?
The OSID number is just basically the cvv number or security number for your bank card. The three digit number on the back of your card, if your in Australia.
How do you test a beam detector?
How do you activate a beam detector?
Optical beam smoke detectors work on the principle of light obscuration, where the presence of smoke blocks some of the light from the beam, typically through either absorbance or light scattering. Once a certain percentage of the transmitted light has been blocked by the smoke, a fire is signalled.
