Detector testing should be are an intrinsic part of maintaining any fire alarm system. Testing your heat detectors, whether fixed or rate of rise, is quick and easy with Solo Heat Detector Testers.

The Solo range of detector testing equipment includes two types of heat detector tester – wired and cordless.

The Solo 423 and the Solo 424 are wired heat detector testing units, 120V and 240V respectively, that generate enough heat to activate a heat detector within seconds. These heat detector testers are a low-cost alternative to the cordless version and are ideal if portability is not a concern.
