Replace Safety Beams in Pairs

| Posted 10.17.2012 | Technical Bulletins

Replace Safety Beams in PairsInfrared photoelectric safety beams are included in Linear’s residential garage door operator line (LDO, LSO, LCO, & LDCO Models) and are available for the commercial operator line. These safety beams are required by UL 325 as secondary entrapment protection devices.

For replacement purposes, Linear offers the Model HAE00002 and HAE00056 safety beams kits. These complete safety beam sets include a safety beam receiver, a safety beam sender, and press-on wiring splices. The units are supplied as a matched pair and may not function if installed mixed with older or existing safety beam units.

IT IS IMPORTANT THAT THE SAFETY BEAM SENDER AND RECEIVER IS INSTALLED AS A PAIR. NEVER REPLACE JUST A SENDER OR RECEIVER, ALWAYS REPLACE BOTH UNITS!

As a reminder, a warning label in each kit directs the installer to “INSTALL OR REPLACE ONLY IN A MATCHED PAIR”.

The safety beams must be present and functioning or the operator will indicate a beam fault and prevent activation.

Many reported problems with safety beams can be traced to high resistance splices in the wiring. It is recommended that the press-on splices provided with the replacement beam sets be used to minimize this problem These press-on splices are also available in a 100 piece kit for use during initial installation with pre-installed wiring. The Gel Cap Kit can be ordered with stock number HAE00020.
