Testing your duct limit switch is a critical step to ensure the proper functioning of your system in case of a fire. Firestat duct high limit units are designed to accurately monitor the temperature inside your duct system. If high temperatures are detected, the Firestat automatically shuts off the fan system to prevent the fire from spreading.
Before shipment, our Firestats undergo rigorous testing to guarantee their reliability. Nevertheless, we strongly advise testing your duct limit switch at home for an extra layer of safety. Regular testing is especially important if you suspect that the unit may not be working properly or want to verify its performance over time.
How to test your Duct Limit Switch
- Connect the Firestat: Begin by wiring the Firestat to your fan system.
- Set the desired temperature: Adjust the Firestat to your preferred temperature limit.
- Raise the heat around the unit: Gradually increase the heat around the probe to exceed the set temperature.
- Observe the fan system: The fan should automatically shut off when the air temperature around the probe surpasses the set limit.
- Reset the Firestat: After testing, pull back on the manual switch to reset the unit.
If the Firestat performs as expected during testing, it is ready for installation and use. Remember to regularly test your duct limit switch, especially before installation, to ensure it is working effectively.
