Waterflows and Tamper Switches
All about EC.02.03.05 – EP 2 – Vane and pressure type waterflows, tamper switches, and mechanical waterflow devices.
Are your sprinkler and fire alarm ITM testing waterflow and tamper switches correctly? How do you know? In my experience through years of testing, watching others, and interviewing certifies technicians, waterflow and tamper switches are one of the most commonly missed failed devices due to improper testing methods.
For proper testing, both vendors (or someone certified in both sprinkler and fire alarm) need to be on site.
In this video, we show you a failed vane type water flow device and how it continued to pass through improper testing methods. Then we discuss how to properly test these devices.
