M100 FireGard™ Closing Systems Data Sheet

M100 FireGard™ Systems
Simple, safe and reliable M100 automatic resetting fire door systems are available in chain, crank or motor operation. Save money on daily operation, testing and resetting with an M100 operator. UL approval allows Cornell to retrofit M100 motor, chain and crank operators to most manufacturers' fire doors while maintaining the door's listing agency ratings. M100 systems are directly wired for activation by fire alarm systems, local detectors or power failure.

M100™ Fire Door Motor Operated Systems

Options:
Battery backup prevents unplanned door closure due to power failures for up to 8 hours. Also functions as a backup DC power source for local warning devices and detectors during power failures.

HP: 1/3, 1/2, 3/4, 1 1/2, 2, 3, 5
Voltage: [115v single] [230v single] [208/230v three] [460v three] phase service

Recommended for all fire doors where the convenience of electric M100 FireGard Motor Operation is desired.


M100 FireGard™ Chain or Crank Operated Systems
For use on fire doors, insulated fire doors and counter fire doors. Automatically closes fire doors during building alarm, smoke detector activation or power failure. Rate of descent will not exceed 12" per second. External releasing devices are not required, eliminating costly wiring. Can be retrofit to most manufacturers' existing fire doors.

Features and Benefits:

Options:
Can use 120 Volt AC, 24 Volt AC or 24 Volt DC Power from an external source or central alarm system. Optional battery backup can hold the door in the open position for up to 8 hours, preventing unwanted drops due to temporary power outages. It can also be used to power local detectors.
