How do you test smoke beams?
Hold the “No Alarm” test filter section over the receiver lens. The alarm should not sound after 15 seconds and the green LED should continue pulsing. Test filters verify the sensitivity setting of beam smoke detectors.
How do I know if my smoke detector is photoelectric?
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.
How do I know what kind of smoke detector I have?
What is the 0.7 rule?
NFPA 72 requires that all points on the ceiling have a detector within a distance of 0.7 times the listed spacing of the detector. This ensures that when detection is used, the entire space on the ceiling is covered by detection. This requirement is commonly called the Point 7 (0.7) Rule.
What is the range of smoke detector?
Smoke detection devices have an individual coverage of a 7.5m radius, while the figure is 5.3m for heat detection devices.
What is a reflected beam smoke detector?
Reflected Beam Smoke Detection Unlike traditional detection systems, Reflected Beam Smoke Detectors were designed for spacious rooms, open areas, and high ceilings; their innovative features make them popular choices for spaces like warehouses, atriums, arenas, and churches.

What size wire do I need for a beam smoke detector?
The conductors used to connect beam smoke detectors to control panels and accessory devices should be color-coded to reduce the likelihood of wiring errors. Improper connections can prevent a system from responding properly in the event of a fire. Installation wire used for the beam detector shall be no smaller than 22 AWG (1.0 mm2).
What is beammmk?
BEAMMMK The BEAMMMK allows System Sensor reflected beam detectors and reflec- tors to be mounted to either a vertical wall or the ceiling. The kit allows for additional alignment range in cases where the detector and reflector cannot be mounted within 10° of each other.
