GENERAL DESCRIpTION
System Sensor Model BEAM1224A/BEAM1224SA is a long range projected
beam smoke detector designed to provide open area protection. It is to be used
with ULC-listed, separately supplied power (4-wire) control panels only. The
detector consists of a transmitter/receiver unit and a reflector. Smoke entering
the area between the transmitter/receiver and reflector causes a reduction in

Disable the zone or system undergoing maintenance to prevent unwanted alarms. Detectors must be tested after installation and following periodic maintenance. The sensitivity of the BEAM1224A/BEAM1224SA may be tested as follows: C0266-00 NOTE: Before testing the detector, check for the presence of the flashing SENSITIvITy SELECTION green LED at the receiver, making sure not to disturb or block the beam. -
Page 9: Maintenance Note
For the BEAM1224A this test does not satisfy the requirements of NFPA72 and/or ULC for periodic maintenance and sensitivity verification of beam type detectors. For the BEAM1224SA this test in conjunction with the complete reflector blockage test (see step 4 of the Installation/Alignment pro- cedure in this manual) does satisfy the requirements of NFPA72 and/or ULC for periodic maintenance and sensitivity verification of beam type detectors. -
