M100 FireGard™ Closing
Systems Data Sheet
M100 FireGard™ Electric Motor Operated Systems
Model FS,
cULus listed, FM approved M100 system operator; part of a reliable, slow closing
fire door system that never needs to be mechanically reset and features easy
system testing at the floor level. Open drip-proof motor, removable without
affecting setting of limit switches. Centrifugal governor. UL listed thermal
overload protection. Solenoid brake. Planetary gearing capable of being driven
backwards or forwards. Rotary limit switches. Transformer with 24 volt control
secondary. All integral components pre wired to terminal block. Automatic
closure activated by fusible link or central smoke / fire alarm system. Doors do
not require a releasing device when activated by alarm signal. Doors shall be
fail-safe and close upon power failure. Resetting of spring tension or
mechanical dropouts is not required. Upon restoration of power, replacement of
the fusible link or clearing of the alarm signal, doors shall immediately reset
by opening with the push button.
HP: 1/3, 1/2, 3/4, 1 1/2, 2, 3, 5
Voltage: [115v single] [230v single] [208/230v three] [460v three] phase serviceRecommended for all fire doors where the convenience of electric M100 FireGard Motor Operation is desired.
Optional F-BBU Battery Back-up System to M100 Model FS motor operators to add a four hour time of door open time in the event of a power failure. Can power local detectors and warning appliances. Allows for programming open/ close obstruction cycling should the sensing edge encounter a stationary obstruction in the opening during AC power alarm signal closing.
M100 FireGard™ Chain or Crank Operated Systems
Manual
M100 system operators; part of a reliable, slow closing fire door system that
never needs to be mechanically reset and features easy system testing and
resetting. These compact chain and crank operator designs include a built-in,
automatic reset release device for connection to a central alarm system or local
detectors - no external release device is required. Units will close
automatically upon alarm or power failure in excess of 10 seconds. Resetting
spring tension or re-engaging the operator is not required. Operators safely
stop the curtain in any position; will not excessively back wind. Accept 24 VDC
or 115 VAC or 24 VAC power. UL 864 listing. 24 VDC output for close warning
device.
Recommended for fire doors that do not require the daily operation convenience of a motor operator and that will have the required access to the hand chain or crank operator. Available for use on all counter fire doors and fire doors to 34' wide or 28' high. Crank units available for units less than 12' high. Chain or crank operation is not recommended for doors that will be used frequently.
