Formed by:

• 3-meter long temperature sensor that closes a contact at a selected temperature.
• Temperature selector with scales between 0 and 300 ºC.
• Resistance of 1 K, to prevent any short-circuit, when it enters into alarm and end-of-line resistor for its connection to a controlled loop of a central fire detection.
• Mechanized metal cabinet for wall mounting, with openings for a probe output and anentry for cables. Measurements: 160x110x70 mm.
• Power supply: 24 VCC. Power consumption in alarm:20 mA.
