• DO NOT attempt repair or service of your release device unless you are an Authorized Service Technician.
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.

INSTALLATION

Classification:
Releasing device as defined by Underwriters Laboratories.
Installation Requirements:
Intended for “Indoor Dry” locations; all wiring must be performed in accordance with the most current version of NFPA 72 - National Fire Alarm Code and the National Electric Code.

MOUNT THE RELEASE DEVICE

Installation procedures vary according to door types. Refer to door manufacturer’s recommendation that applies to your door.
1. Mount the release device on a vertical surface with chain end link exiting side of enclosure.
2. Secure the release device enclosure with fasteners (#10 is the minimum size recommended). If installing in masonry, use concrete anchors (not provided).
3. Install hardware (sash chain or 1/16 cable, eyebolts-hook, fuse links, turnbuckles—not provided) according to door manufacturer’s recommendations. NOTE: The end link direction
of pull must be perpendicular to the side of the release device enclosure. Install an eyebolt a minimum distance of 12" from the release device to adequately redirect sash chain pull.
4. Install end link by pressing mechanical reset to allow insertion of end link. Push end link completely in and release mechanical reset to latch end link.
5. Remove sash chain or cable slack by adjusting turnbuckle.

WIRING

WIRING INSTRUCTIONS
Verify wiring configuration with that recommended by door manufacturer for use of this product with specific door and accessories being utilized. 18-gauge wire is recommended.
1. Turn off power supply sources for the release device as well as the door operator, if applicable, before beginning.
2. Verify voltage rating of release device to power source being utilized. Voltage is indicated on the side of the unit. Verify that power is disconnected before proceeding.
3. Connect 24Vdc power to terminal board positions 1 and 2 (Figure 2). Observe proper polarity. 24Vdc power input from an approved UL 1481 regulated power supply with battery backup.
To reduce the risk of SEVERE INJURY or DEATH:
• ALL electrical connections MUST be made by a qualified individual.
• Disconnect power at the fuse box BEFORE proceeding. Release device MUST be properly grounded and connected in accordance with local electrical codes.
• ALL power wiring should be on a dedicated circuit and well protected. The location of the power disconnect should be visible and clearly labeled.
• ALL power and control wiring MUST be run in separate conduit.
• Installation of ALL wiring and connections, including Class 1 and Class 2 circuits, shall be performed in accordance with, but not limited to, the latest NFPA, UL and N.E.C. standards and codes. In addition, ALL installations subject to Canadian standards shall be performed in accordance with the Canadian Electrical Code, Part I, with respect to wiring material type, wiring gauge related to power capacity requirements and circuit length and wiring methods.
