Heat Detector Testers

Buy a heat detector tester to prove that rate of rise (A1R) and fixed temperature heat detectors respond, from floor level and without damaging the detector. Choose the cordless Solo 461, mains-powered Solo 423/424, or a Testifire all-in-one head that tests smoke and heat with one tool, as a head unit or complete kit with poles.

Heat detector tester buyer's guide

Cordless, mains or all-in-one?

• Cordless: the Solo 461 kit and Solo 460 head run on Solo 770 battery batons, so there is no cable to trail across site.
• Mains powered: the Solo 424 (220/240V) and Solo 423 (110/120V) suit continuous use where power is available; the Solo 425 adds a 5m extension cable.
• All-in-one: Testifire XTR2 heads test smoke and heat; the Testifire 2000/2001, 6201 and 9201 also test CO. Ideal for multi-sensor detectors.

Rate of rise and fixed temperature detectors

A heat detector tester blows controlled hot air into the detector to raise its temperature. A1R rate of rise detectors usually respond quickly; higher-temperature fixed detectors such as BS and CS take longer to reach their response temperature. Follow the tester and detector manufacturers' instructions and never use a naked flame or an unregulated heat gun, which can damage the detector housing.

Heat detector tester FAQs

How do you test a heat detector?

Place a heat detector tester over the detector and apply heat until the detector and panel go into alarm, then allow it to cool and reset. Pressing a test button does not prove the heat sensor responds.

Can I test a heat detector with a hairdryer or heat gun?

It is not recommended. Use a purpose-made heat detector tester that delivers controlled heat and shields the detector, so you do not overheat or damage it.

How often should heat detectors be tested?

Under BS 5839-1, every detector, including heat detectors, should be functionally tested within each 12-month period, usually spread across six-monthly service visits by a competent person.

Will one tester fit all heat detectors?

Most heads fit standard point detectors. Some detectors need an adaptor, such as the Testifire XTR2 head adaptor for Fike heat detectors; check the product page.
