What is a beam type smoke detector?
Beam Smoke Detector (Reflected Beam Smoke Detector) A device which senses smoke by projecting a light beam from a transceiver unit across the protected area to a reflector that returns the light signal back to the transceiver unit.
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.
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.
How do I know what kind of smoke detector I have?
If you are unaware which type of smoke detector you have in your home, now is the time to check. You can do so by taking the smoke alarm down and look at the back for either “Photoelectric” or “Ionization,” or a symbol with the letter “P” or “I” on the back.
What are different types of smoke detectors?
There are two types of smoke alarms in general use for home smoke alarms: photoelectric and ionization. These smoke alarms sense the presence of smoke differently. The type of smoke produced by a fire depends on the type of fire. Flaming fires produce a different type of smoke than smoldering fires.
How do you test 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 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.

How do I know if my smoke detector is bad?
The Signs Which Indicate Your Smoke Detector May Be Failing (or Has Failed!)
- The smoke detector is intermittently going off for no reason.
- Random chirping, even after replacing the battery.
- The test button fails to operate the siren on the smoke detector.
Why do hard wired smoke detectors go off for no reason?
A hardwired smoke alarm could go off because of a dead backup battery, power surges, improper installation, dust in the air or humidity.
What type of smoke detector is the beam1224?
The BEAM1224 is a 4-wire, single-ended, reflected type beam smoke detector that includes an 8″ reflector. Loading… No documents found. Loading…
What is a beam1224?
System Sensor Model BEAM1224 is a four-wire conventional reflected beam smoke detector, which is uniquely suited for protecting open areas with high ceilings, where other methods of smoke detection are difficult to install and maintain.
How does bebeam 1224 work?
BEAM1224 consists of a transmitter/receiver unit and a reflector. When smoke enters the area between the unit and the reflector, the smoke causes a reduction in the signal. When the smoke level reaches the predetermined threshold, an alarm is activated.
What are the advantages of single-ended reflective reflective beam detectors?
An advantage of this single-ended reflective design is that it is much easier to install than the dual-ended projected beam detectors. Alignment is quickly accomplished via an optical sight and a two-digit signal strength meter incorporated into the product.
