Product Description:

The door interlock system prevents more than one door from opening at the same time, under normal conditions. The door interlock system is electrically operated using magnetic locks and magnetic door switches. Pushbuttons installed at the doors are for overriding the magnetic locks in the event of an emergency. Visual and audible alarms for when a door is opened and will silence upon closing. This system is designed to meet recommended and/or mandatory requirements for maintaining containment levels based upon standards of the below governing organizations.

  • National Institutes of Health (NIH) Design Requirements Manual for Biomedical Laboratories
  • Laboratory Biosafety Guidelines of Canada

The door interlock system can be used in many applications for environmental and safety control. Some examples include: laboratories and clean rooms where airlocks are utilized, darkrooms, x-ray and other treatment rooms, and more.

Note: If this system is installed in an animal laboratory (ABSL), the audible alarm can be easily disconnected to not disturb the animals.

The flush control panel comes with a stainless steel flush cover and 10”H x 8”W x 4”D steel back box. The surface control panel comes with a hinged non-detachable cover from the 10”H x 8”W x 4”D surface box. The surface box with cover is made of steel with a baked enamel gray coating.
