This 240V Time Delay Emergency Curtain Drop with alarm from ControlTech has an electromagnetic force to hold the arm securely until power interruption. During power failure, it will release its spring-loaded arm to release the curtain winch (not provided) after a 5-minute delay. The release arm is constructed of stainless steel and the control unit is sealed in a watertight box. Battery-free operation. Not affected by cold weather.

This PowerDrop is equipped with an alarm. The alarm is signaled by a waterproof micro switch on the hinge. Alarm signal can be normally open or normally closed.

Installation: Installation of the PowerDrop is simple. Included in the box is all of the hardware you will need to be up and running. With a nut driver and pliers you can have the PowerDrop mounted and connected to your winch in about 15 minutes. Connecting power is easy too, just plug into your 120, 208 or 240 VAC outlet.
