Ideal for difficult to wire locations, situations where room aesthetics are critical, or where hazardous materials exist, the LST provides the ultimate in installation flexibility. (Ademco 1) Remarkably cost-effective, the attractive, low profile unit blends easily with any décor and provides benefits rarely found in smoke detectors in this price range. Smart Check remote maintenance reporting automatically alerts the central station when it is in need of service, and built-in drift compensation continuously corrects sensitivity variances caused by dust.

The LST is UL 268 listed for use in both commercial and residential applications. All trademarks are property of their respective owners. Mounting Instructions. First, determine the best location for the smoke detector that provides strong wireless transmission paths and proper smoke detection. A good transmission path must be established from the proposed mounting location before permanently installing the detector. To mount the detector, install the mounting bracket on the ceiling or on the wall (if local ordinances permit). Use the two screws and anchors provided. Prior to mounting the detector to the mounting bracket, the system must “enroll” the detector’s ID. Turn the detector in a clockwise direction in the mounting bracket until it clicks into place. Test the detector immediately after completing the installation and refer to the control system’s instructions for additional information concerning the use of wireless smoke detectors.
