The Siemens DT-135WP is a weatherproof fixed-temperature thermal detector rated at 135 deg F (57.2 deg C), providing rugged heat detection on conventional initiating device circuits for areas unsuited to smoke sensing.

Compliance

• UL 521 (heat detectors)
• ULC listed
• FM approved
• NFPA 72 compliant

Key features

• Fixed-temperature operation at 135 deg F (57.2 deg C)
• Self-restoring element after the heat condition clears
• Weatherproof construction for indoor and outdoor placement
• Conventional two-wire initiating device circuit wiring
• Suited to parking garages, loading docks and industrial spaces
• Low-profile housing for surface mounting

Siemens thermal detectors add fixed-temperature heat detection where smoke sensing is impractical because of dust, fumes, humidity or temperature swings. Typical placements include parking garages, loading docks, mechanical rooms, kitchens and industrial spaces that demand a rugged initiating device on the alarm circuit.
