Motor Operation for Fire Rated Doors




  • Motor operation is the most effective and consistent method of opening larger, higher cycle doors and offers the following benefits:
  • Door Longevity: Offers the most consistent method of operation, and as such, maximizes door longevity
    Ease of Use: Can link to one-touch, or even no touch, opening triggers such as a push button station or a loop detector
  • Safety: Accommodates entrapment devices such as photo eyes and sensing edges
  • Remote Activation: Can be integrated into master building controls to operate doors remotely
  • Durable: Can be designed to withstand weather, chemicals, or even explosions


Motor operation does require power to the opening and enough clearance to mount the motor. In the event of a power outage, auxiliary operators can be used (push up or chain, depending on door size and configuration). You often see motor operators in parking garages, distribution facilities, paint booths, and car washes.

AlarmGard® Plus Motor


The AlarmGard Plus is a chassis operator that is part of the AlarmGard system. It is a failsafe operator that safely closes a fire door in response to an alarm signal or power outage. When the alarm is cleared or power is restored the door will automatically resent itself, saving time and money. In addition to all of the standard AlarmGard features, the AlarmGard Plus also has an auxiliary chain hoist and a battery back-up. The battery back-up prevents the door from closing for up to 8 hours, due to a power failure.
