Aritech DB702 Conventional Detector Base

1. Product Name: Aritech DB702 Conventional Detector Base

2. Description:

What Is the Aritech DB702 Detector Base?

Aritech DB702 is the standard point-type detector base used for all 700 series conventional fire detectors. It secures the detector to the ceiling and provides connections for zone wiring. Its slim profile (9 mm high) and weight of 42 g make for unobtrusive ceiling installation.

Operating Principle

The base allows connection via the 6 terminal to a 2-wire zone line and, where required, to a COM/NO/NC relay or remote indicator. Its normally closed continuity switch ensures line continuity when no detector is installed; when a detector is fitted to the base, the switch opens and standard open-circuit monitoring is enabled. This means that if a detector is removed, the panel can report a fault.

Role in Fire Detection Systems

DB702 is the connection point between the detector and zone cable in a conventional fire detection system. Selecting the correct base makes line testing easier during installation and ensures that detectors remain securely in place during operation. All 700 series detectors use the same base, making it easier to switch between detector types on site; for example, replacing an optical detector with a heat detector does not require any wiring changes.

Why Choose It?

• Easy installation: Detectors are fitted without force, in one direction and in the correct position.
• Continuity switch: Cable testing can be carried out during installation before detectors are fitted.
• Locking mechanism: The lock, which works with the detector, prevents unauthorised removal.
• Versatile connection: 6 terminals support zone, relay and remote indicator connections.

Installation and Commissioning

The base is fixed to the ceiling and the zone cable is connected to the terminals. Once wiring is complete, the continuity switch is closed, allowing the line to be tested end to end before detectors are fitted. After testing, detectors are fitted in the correct position using the one-way push-fit and can be locked if required. For surface wiring, DB806 can be used with a surface mounting box.

Frequently Asked Questions

Which detectors is DB702 compatible with? It can be used with all Aritech 700 series conventional detectors.

What happens if a detector is removed? Since the continuity switch remains open, the panel reports a fault on the zone.

Can the base be used outdoors? No. DB702 is for indoor use; its operating temperature range is -10 to +55°C.
