Aritech DT713-7 700 Series Conventional Heat Detector, 70c Class B

Aritech DT713-7 700 Series Conventional Heat Detector, 70c Class B

The 700 series conventional detector line includes a range of temperature detectors:

• The DT713-5 is a category A2 temperature detector with a fixed temperature threshold of 57°C and built in rate-or-rise functionality
• The DT713-5R has the same specifications as the DT713-5, but in addition includes a built in potential free changeover relay
• The DT713-7 is a category B temperature detector with a fixed temperature threshold of 70°C and built in rate-or-rise functionality

700 Series detectors continually monitor their own sensitivity and operational status. Once a day they perform a full diagnostic test that includes dynamically testing the sensing chamber and internal electronics. Any abnormal statuses are reported locally on a fault LED on the detector, and signalled back to a compatible CIE.

The detector base

Every 700 series base features a continuity link between LINE IN (1) and LINE OUT (2) terminals of the conventional detector circuit. The base is supplied with the link in closed position. The link is enabled by default allowing you to check the zone wiring using only the bases.

The link will automatically disconnect when a detector is inserted, allowing the panel to generate a fault message when the detector is removed.
