FireflyTM Releasing Devices
A releasing device is an electro-mechanical device that allows a manually released fire door to be connected to a smoke detector or central building alarm system. Upon activation of a smoke detector or central building alarm system, the releasing device will release the fire door and allow it to automatically close. All releasing devices must be listed by an independent testing laboratory and comply with UL-864 (Control Units and Accessories for Fire Alarm Systems). The full line of Swastik Firefly releasing devices are failsaf e in design.
Firefly™ Releasing Devices
Swastik offers 3 Firefly releasing devices to meet the various needs of building alarm systems. Firefly releasing devices are solid state and come with a variable alarm time delay factory preset to 10 seconds, but can be field set to a maximum of 60 seconds. Upon the activation of a smoke detector or central alarm system, the Firefly releasing device will not release the fire door until the time delay has elapsed. If the some detector or central alarm system is reset before the time delay has elapsed, the door will not automatically close. This time delay feature is to prevent the closing of fire doors due to power brownouts.
Firefly III™
The Firefly III releasing device is made to connect to a building central alarm system. It is powered by 24V DC power wired directly into the building alarm control panel and is supported by the building alarm control panel emergency power source. In case of building power failure, the fire alarm control panel emergency power source will power the Firefly III and the door will not close unless there is an alarm activation.
Firefly III Plus
The Firefly III Plus releasing device is made to be a stand alone releasing device that does not need to, but can, be connected to a building central alarm system. It has all of the features of the Firefly III plus a built in battery that can power up to 2 smoke detectors and I or sounder strobes for as long as 72 hours in the event of a power failure. This provides fire protection during power failures, preventing unnecessary door closings, without the expense of a central battery back-up system. The Firefly III Plus is multi-voltage 120 VAC, 24 VAC and 24 VDC.
Firefly IV MV
The Firefly IV MV releasing device is made as a stand alone releasing device or one that can be connected to a building central alarm system. It is multi-voltage 115 VAC, 24 VAC, and 24 VDC and can power a 24 VDC closing warning device. The Firefly IV MV will allow the door to close in the event of a power failure that lasts longer than the 10 second time delay to assure there is fire protection during sustained power failures.
