Description
The Fike 60 series Thermal Detectors operate on the rate compensation principles. These principles offer the fastest possible response with the least probability of a false alarm, for a thermal type detector. Thermal detectors are normally open switches which automatically reset when the temperature returns to normal. The thermal detectors are available in 135°F (57.2°C) or 194°F (90°C) temperature settings. All units are hermetically sealed, shock and corrosion resistant and tamper proof. Units are available for interior, weather-proof and explosion proof applications. The Interior Mount Detector has a 2” (51 mm) diameter plastic base with terminal screw type connections for fi eld wiring. The Explosion Proof Detector has a hexagonal wrench grip bushing with a 1/2” (15 mm) conduit threads and is approximately 4 1/8” (105 mm) long.
