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
  • Model LM21AAFCBVB – is equipped with a voice board to broadcast a prerecorded evacuation message

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
  • Model LM21XPBBVB – is equipped with a voice board to broadcast a prerecorded voice evacuation message

FM Approved

3 Hour approved for smoke and fire doors in dividing fire walls with openings not exceeding 120 sq. ft. in area. • 1.5 Hour approved for smoke rated shutter in vertical shaft openings not exceeding 120 sq. ft. in area. • .75 Hour approved for smoke contained doors in corridor or room-partition opening not exceeding 120 sq. ft. in area. • 1.5 Hour approved for rolling smoke doors in exterior wall opening not exceeding 120 sq. ft. in area.

The Alpine Auto-Smoke, Fire-Tite® smoke contained door has all the features of the Fire-Tite® with the addition of an “S” rating for smoke leakage. The Auto-Smoke, Fire-Tite® smoke rated shutter utilizes a vinyl smoke seal on the bottom bar, brush seals on the guides and lintel to stop the movement of smoke fire through the rolling smoke door. This prevents property damage and health risks.

Auto-Smoke, Fire-Tite® rolling smoke door curtains are constructed of galvanized steel in IMB-V7 Insulated slats, and can be finished with powder coating or baked enamel finishes. Each smoke contained door is equipped with a 22 gauge steel hood formed to fit the contour of the end brackets. Durable ductile iron endlocks with 1/4″ semi-solid rivets and wind locks are available. Our fire and smoke rated shutter supports and brackets are all steel plates no less than 1/4″ thick. Alpine’s Torsion Counterbalance Assembly is state of the art, providing maximum security and ease of use.
