Aritech DB2002 Standard Detector Base

1. Product Name: Aritech DB2002 Standard Detector Base

2. Description:

What Is the Aritech DB2002 Standard Detector Base?

The Aritech DB2002 is a standard mounting base designed for ceiling-mounted 2000 series addressable point detectors. Its wide body, approximately 10 cm in diameter, and low profile of just 9 mm provide a discreet appearance on the ceiling. The loop wiring is connected to the base, and the detector head is fitted to the base to complete the installation.

Operating Principle

The DB2002 contains no active electronics; its purpose is to safely connect the loop wiring, earth connection and remote indicator output to the detector. The 2-core loop cable is connected to the terminals in the base, and the connection is completed by turning the detector into place. The moulded locking mechanism in the base makes it difficult for unauthorised persons to remove the fitted detector once a small tab has been broken off.

Role in Fire Detection Systems

In an addressable fire detection system, the base provides both the mechanical and electrical connection for the detector. All point detectors in the 2000 series are compatible with the same standard base, allowing optical, multisensor or heat detectors to be easily interchanged on the same base. This speeds up detector replacement during maintenance and makes it possible to upgrade the system without disturbing the wiring.

Why Choose It?

• Common base design: All 2000 series detectors fit the same base, simplifying stock and project management.
• Slim design: A height of 9 mm provides a neat, unobtrusive ceiling installation.
• Locking feature: The moulded locking mechanism helps prevent unauthorised removal of the detector.
• Remote indicator support: A dedicated terminal is provided for connecting a remote indicator.
• Environmentally compliant manufacturing: Complies with CE, REACH, RoHS 2 and WEEE requirements.

Installation and Commissioning

The base is screwed to the ceiling using the loop cable entry. The loop in and out conductors, earth and, if required, remote indicator connections are wired to the terminals. Once wiring is complete, the detector head is fitted to the base and turned to lock it in place. To enable locking, remove the tab on the base before fitting the detector. The product is suitable for indoor use in dry environments only; addressing is set using the rotary switches on the detector, not the base.

Compatible Products

The DB2002 base is used with 2000 series point detectors, such as the Aritech DP2061N addressable optical smoke detector, DP2061T multisensor detector and DT2063N heat detector. According to the manufacturer, it is also compatible with the AS2368CAP-W locking cover and AI672 remote indicator. The DB2004 deep base can be used where additional space is required behind the detector, while the DB2016 isolator base can be used to protect the loop against short circuits.

Frequently Asked Questions

Does the DB2002 base set the address? No. The address is set using the two rotary switches on the detector; the base is for connection and mounting only.

Can the detector be prevented from being removed? Yes. Once the tab on the base has been removed and the detector fitted, it is locked in place, making unauthorised removal more difficult.

What is the difference between the DB2002 and DB2004? The DB2002 is a slim standard base with a height of 9 mm; the DB2004 has a deeper 17 mm profile, providing space for additional electronics behind it.
