The Curtain-Minder 5010 is a combo packet with the CM 5000D, WK 1510, and T2440.

The CM 5000D is the first curtain emergency ventilation control for both tunnel and conventional poultry rearing houses and confinement buildings with curtains or fall out panels. A knob on the front of the Curtain-Minder controls the delay time for releasing the curtain winches. The delay is adjustable between zero and ten minutes. Zero or near zero allows the operator to test the systems and the curtain winching system quickly. Ten minutes may be practical for young poultry and livestock, and other sizes under some extreme weather conditions. The time in between zero and ten minutes is used to provide protection while ignoring local electrical problems. The adjustment also provides the operator the ability to match the transfer time on an automatic standby generator.

The WK 1510 is the original WK 1500 U but with a reed switch. The reed switch can be used as an alarm output or for "Automatic Tunnel Mode" using the CM 5000D. The reed switch is a good safety feature. When the reed switch is wired to the normally closed circuit on your alarm system, anytime the winch opens it sets the alarm off. The WK 1510 is packed standard with the CM 5010. We want to provide as much safety as possible. When using the WK 1510 on all winches with the CM 5000D, the winches will all fall at the same time.
