Ideal for emergency ventilation in your livestock barn, the Time Delay Emergency Curtain Drop from ControlTech has an electromagnetic force that holds the arm securely until power interruption. During power failure the PowerDrop will release its spring-loaded arm which will release the curtain winch, not included, after a 5-minute delay. Release arm is constructed of stainless steel and the control unit is sealed in a watertight box. This all-weather controller does not require batteries.

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