Guardian Door Safety Devices

Infrared Presence Sensors

NELCO infrared presence sensors provide a curtain of security providing peace of mind that your patients and staff will enter and exit the treatment room safely. There are three models available each of which provide a harmless and invisible curtain of light which detect objects in and around the door openings.  When an object is detected by a sensor the door if in the closed position will not open or if the door is moving it will stop and reverse direction. In addition, to provide even more peace of mind in the unlikely event that a sensor is damaged or fails the system will disable the door operator preventing any potential hazards.

The NELCO infrared safety devices can be installed on any radiation therapy treatment room door with an automated door operator.

Features & Benefits:

Guardian Swing Door Infrared Presence Sensor

• Mounted on the door near the top edge out of harm’s way
• Rotating Cam for adjustment of light curtain

Pressure Sensitive tape switches

When a NELCO pressure sensitive tape switch comes in contact with an object and 4 lbs of pressure is applied the switch will compress activating the switch sending a signal to the door operator.  The door will then either stop or stop and reverse direction. These safety edges are designed in a fail-safe configuration which means if a switch is damaged the door operator will cease operation until the switch is repaired.

The tape switches can be applied to any radiation therapy swing or sliding treatment room door with an automated door operator.

• Typically mounted in a set of 5 on the leading edge of a single leaf slide door.
