FIRE DOOR RELEASE SYSTEMS
The Firefly II-MV, Firefly II Plus, Test-A-Fire, and Sure Fire Plus Systems are engineered for reliable performance and extreme fire protection, and are designed to meet safety and cost concerns. Firefly II-MV and Firefly II Plus Systems are for use on fire doors that must be connected to smoke detectors/alarm systems, doors requiring only annual testing, doors installed so complete door is accessible, and there is minimum occupancy around the door opening. The Firefly II-MV and Firefly II Plus Systems feature a fail-safe, time-delayed releasing device to prevent mechanical drop during momentary power failure.
The Test-A-Fire System is for use on fire doors that must be connected to smoke detectors/alarm systems, doors requiring testing several times during the year, doors mounted above a ceiling with limited access, and doors installed in locations with limited occupancy of general public.
