Door Safety / Interlock Switch

Automatically De-Energize UV-C Fixtures Safely

UL-1995 requires while ASHRAE recommends that all HVAC access points (doors/panels) be secured with a safety interlock switch that automatically de-energizes the UV-C system when opened.

The switch is a ‘normal open’ circuit that is depressed when the door is closed, energizing the UV-C system. When any access door is opened, the safety switch “breaks” the circuit, turning off all UV-C fixturing.

UV Resources offers the door safety/interlock switch for application on all HVACR UV-C applications for safety of the users. The switch is used to de-energize the UV-C fixturing when access doors/panels are opened.
