Frequently Asked Questions

Q1. What does "HST" in HST Series stand for?
A1. "HST" stands for "heat stick tester". In the fire alarm industry, probe style heat detectors (such as rate compensated detectors) are commonly referred to as "heat sticks"

Q2. Is the HST more expensive than a "bench tester"?
A2. A bench tester made for probe type fire detectors costs more than the HST. At about $3,500 to $4,500 for a bench type tester, plus the added cost of removal and re-installation this method actually costs many times more than the HST tester.

Q3. How can I identify the type of and manufacturer of my heat detector?
A3. Probe type heat sensors all look very similair. Look for Manufacturer and temperature rating on detector. Fenwal "Detect-a-Fire" uses a stainless steel shell that is 5/8 inch diameter. "Thermotech uses an aluminum shell that is 17/32 inch diameter

Q5. Is the HST Series Heat Detector Tester approved by heat detector manufacturers?
A5. The HST Series Heat Detector is not officially approved by any heat detector manufacturer, however, the HST Series Heat Detector Tester is often recommended by manufacturers as an acceptable testing solution. We recommend contacting the heat detector manufacturer about their recommended testing solution for your application.

Q6. Will a high-temperature HST tester work on all my detectors, regardless of the rated set point?
A6. Overshooting the manufacturers rated setpoint could cause the setpoint to permanantly shift. Always consult the manufacturers test procedure to determine the max test temperature over the setpoint.

Q7. Will the HST heat detector tester work on probe type detectors made by other manufacturers?
A7. Possibly- we are working on testers for other manufacturers, sizes, sensor orientations- send us an email with your requirements.
