MARK SENSOR
DESCRIPTION
The Rixson Firemark FM Series electromagnetic door releases hold fire and smoke barrier doors open until released by a remote smoke detector switch, fire alarm control or sprinkler system. In the event of power failure, doors are released to close automatically, but may be opened or closed manually at any time.
The door holders have a sprayed aluminum finish. All models feature a “multi-voltage” design, allowing them to operate on 12 VDC, 24 VAC/DC, or 120 VAC, thus simplifying both installation and inventory.
FEATURES
• Fail-Safe Operation
• Approx. 35 lbs. (15.9 kg) Holding Power
• Positive Release Button to Initiate Closing Motion when the Electromagnet is De-Energized
DATELs new DMS-20PC-FM Series are the world’s smallest, self-powered, ac frequency meters. Simply connect the ac line to the two rear input terminals, and the unit is fully operational with no additional components or auxiliary power required! Two, 50/60Hz models operate over input voltage ranges of 85-140Vac or 170-264Vac. A third, 400Hz model operates over an input voltage range of 85-140Vac. Despite their small size (1.38" x 0.88" x 1.0"), DMS-20PC-FM meters feature large 0.40"/10.2mm red LEDs that can be read easily from 15 feet away.
