Pro-Tech - Model CM 5000D - Curtain Emergency Ventilation Control System
From Products
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.

Product Details
The CM 5000D sets up the tunnel for you! Once the first winch is locked a timer starts and when the unit sees the last winch connected it is in tunnel mode. If you fail to connect all of the winches within 10 minutes, the curtains open.
PEACE OF MIND - The Curtain-Minder reduces concern about heat prostration and suffocation. The CM 5000D watches for LOW
VOLTAGES and total power outages to release curtains. By adding a thermostat such as Pro-Tech's TherMinder. curtains can be released on high temperature. Three extra safety features are incorporated in the CM 5000D: £ 1) If for some reason the curtains have not dropped in the amount of time you have set on the unit, after 10 minutes the circuit dies and the curtains release. # 2) There is also an alarm output that can tell you if there is LOW AC POWER or NO POWER. If you are using the Curtain-Minder for tunnel houses, the alarm output will also tell you when the winches release. #3) 'Automatic Tunnel Mode'
BATTERY TEST Your battery can be tested in about 25 seconds. No more guessing if the battery is good.
ECONOMICAL Wiring cost is less since the Curtain-Minder uses a low* voltage UL Listed 24-volt transformer (supplied). No high voltage outlets (120-240 volts) are required. The winch kits are low voltage also. One WK1510 winch kit comes with the Curtain-Minder and four more can be added. The CM 5000D is mounted near the breaker panel.
LIGHTNING PROTECTION There is lots of protection added to the outputs and the inputs. The Curtain-Minder is a low voltage device so it is less susceptible to lightning.
