Redi-Release - Solid State Fire Door Release Devices

For Use with Fire-Tite®, Fire-Shut® and Fire-Storm® Doors.

The ideal safety option for fire resistant rolling doors.

Fire Door Release, Release Devices, LM90 Model - Optional Features

The Solid State Securities time delay fire door release device is an optional feature for your fire resistant doors. Alpine® Redi-Release® is normally energized as a fail-safe device for fire doors, and incorporates state of the art electronic security control circuitry.

The Redi-Release series release devices are the ideal safety option for fire resistant doors. These devices are able to respond to emergency conditions generated by manual or automatic initiating devices that are normally closed, and are designed to be used in conjunction with a temperature fuse link system. The Test-Release device features include time delay on alarm and power loss, motor voltage sensing, form C output, proximity/door edge input and trouble diagnostic capabilities. Check model label to be installed to verify applicable features.

CAUTION: As with all releasing device systems, maximum fire protection is provided when installed in accordance with factory specifications and used with fuse link systems. Fail-safe operation can only be provided when input power is applied.

LiftMaster Professional

For Motorized Doors – Electro-Mechanical OperatorsFire Door Release, Release Devices, LM90 Model - Optional Features

The AFCB fire door release device is designed to be used in conjunction with a standard commercial door operator to provide a fully automated door closing system. For use with motorized doors incorporating a reversing electric safety edge. This 120VAC device can power up to four smoke detectors and two horn/strobes or speaker/strobes. This system combines state-of-the-art functionality and advanced features typically found on special-order fire door operators.

LM21AFCB Owners Manuals

  • UL864 Revision 9 compliant
  • Programmable DIP switch delay setting – either 10, 20, 30 or 60 seconds delay of door release to permit passage clearance
  • Internal battery backup system
  • Motor voltage sensing monitors voltage to the operator and activates a mechanical door release upon loss of power to the operator.
  • Obstruction cycling – works in conjunction with the door’s electrical safety edge, reversing the door if an obstruction is encountered
  • Test keyswitch – permits floor-level testing of the system

Non-Motorized Doors

Fire Door Release, Release Devices, LM90 Model - Optional Features

The XP fire door release device provides a fail-safe release mechanism for non-motorized doors and acts as an interface between the door and the fire alarm system. The device required 24VDC power from an approved UL1481 regulated power supply with battery backup, such as a fire alarm control panel. Therefore, installation will require coordination with a fire panel installer.

LM21XP Owners Manuals

  • UL864 Revision 9 compliant
  • Programmable DIP switch delay setting – either 10, 20, 30 or 60 seconds delay of door release to permit passageway clearance
  • Close door detection – prevents door release if the door is kept in the closed position and eliminates door reset service calls or potential system damage
  • On board diagnostic – LEDs for early troubleshooting
  • Testing function – allows routine fire door testing without requiring activation of the central alarm system; easy reset function returns the device to a standby state

Non-Motorized Doors with Battery Backup Option

Fire Door Release, Release Devices, LM90 Model - Optional Features

Versatility allows the XPBB fire door release device to operate on 120VAC, 24VAC or 24VDC power sources. Internal battery backup allows the release device to stand alone from the fire alarm system and act independently in the event of a power outage. The system can provide 24VDC power for up to four smoke detectors and two horn/strobes, mounted on either side of the door. Programmable delay settings, close door detection, diagnostic LEDs, localized testing, and reset capabilities are also standard.

LM21XPBB Owners Manuals

  • UL864 Revision 9 compliant
  • Programmable DIP switch delay setting – either 10, 20, 30 or 60 seconds delay of door release to permit passageway clearance
  • Inputs for normally open – 2-wire or 4-wire detectors and 4-wire normally closed detectors
  • On board diagnostic – LEDs for early troubleshooting
  • Trouble and alarm relays – for communication with the fire alarm control panel, if required
  • Audible trouble sounder – to indicate when the release device is not operational
  • Testing function – allows routine fire door testing without requiring activation of the smoke detector
