IMPORTANT NOTES: • BEFORE attempting to install, operate or maintain the release device, you must read and fully understand this manual and follow all safety instructions. • DO NOT attempt repair or service of your release device unless you are an Authorized Service Technician. INTRODUCTION GENERAL DESCRIPTION The LiftMaster® LM21XP Release Device is UL/ULC listed normally energized fail-safe device designed for use on rolling doors, single-slide and center-parting level and inclined track doors. All models are normally energized fail-safe releasing devices incorporating state-of-the-art electronic control circuitry. The release devices respond to emergency conditions generated from an automatic initiating device and are used in conjunction with a temperature fuse link system. This device is designated to be used with manual doors, but can be used on motorized doors incorporating a fusible link assembly and drop-out mechanism. The release device must be powered from 24Vdc received from an approved UL 1481 regulated power supply with battery backup. The devices can be activated via a smoke detector or an alarm relay from the panel’s Form C dry contact relay. The release device features include a 10-, 20-, 30- or 60-second delay on alarm, closed door detection capabilities, Form C relay outputs for the transmission of alarm and trouble signals transmitted to the fire alarm control panel, an audible trouble sounder, and diagnostic feedback LEDs. 2 INTRODUCTION AGENCY REQUIREMENTS Installation and testing to factory specifications shall be performed by factory authorized personnel for proper operation in accordance with the latest National Fire Protection Association (NFPA), Underwriters Laboratories (UL), National Electrical Code (NEC), local, state, county, district and/or other applicable building and fire standards, guidelines, regulations and codes including, but not limited to, all appendices and amendments and the requirements of the local authority having jurisdiction (AHJ). SPECIFICATIONS To prevent possible SERIOUS INJURY or DEATH: • DO NOT use this device without fuse links installed. • Test every 90 days to assure proper operation of release device.
