ACCESS CONTROLS
Open/Close/Stop push button stations, Key Switches, Exit Loops, Remote Transmitters and various other types of interior or exterior mounted controls. Consult factory for additional options.

SAFETY ENTRAPMENT PROTECTION

Option: Electric monitored sensing edge with a coil cord, take up reel, or a wireless transmitter and receiver type monitored sensing edge

Option: Safety photo sensors mounted to the guides 6” above the finished floor that project an infrared beam across the width of the door. Breaking the beam while the door is in motion will result in the immediate stop of downward travel and reverse the door to reopen to the top limit.

These are the operator options for Alpine’s Mall-Dawn™ security door. Please see our entire line of service door operators. Alpine’s security door operator is UL 325 standard and constructed with the highest quality material and the latest in technical innovation. This ensures that each roll up door motor exceeds the requirements it is meant to achieve. Alpine is sure to have an operator that will meet all your individual specifications.

The Solid State Securities time delay release devices are normally energized as Fail-Safe devices incorporating state of the art electronic security control circuitry.

The Redi-Release™ operable grille release devices respond to emergency conditions generated by manual or automatic normally closed initiating devices, 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.
