Aritech DT2063N Addressable Heat Detector

1. Product Name: Aritech DT2063N Addressable Heat Detector

2. Description:

What Is the Aritech DT2063N Addressable Heat Detector?

The Aritech DT2063N is an addressable heat detector certified to Class A2R and operating with the 2000 series protocol. Its dual-thermistor design and rate-of-rise algorithm can trigger an alarm before the fixed temperature threshold is reached. It is approved to EN54-5 and CPR-certified.

Operating Principle

The detector’s dual thermistors continuously measure the ambient temperature. If the temperature rises rapidly, the rate-of-rise algorithm activates and triggers an alarm without waiting for the fixed alarm point to be reached; for slowly developing fires, the fixed temperature threshold applies. The fixed trigger level can be adjusted via the panel (CIE) for applications requiring a higher temperature threshold.

Role in Fire Detection Systems

Heat detectors are preferred in dusty, steamy or smoky environments where smoke detectors may generate false alarms. Thanks to its addressable design, the DT2063N reports its exact location to the panel when an alarm occurs. The SIA-based protocol, which includes CRC error checking and multi-data bus loop codes, provides reliable and fast communication between the panel and the device.

Why Choose It?

• A2R-class detection: The rate-of-rise algorithm enables early alarm activation.
• Adjustable threshold: The fixed trigger temperature can be raised via the panel.
• Easy addressing: A numerical address from 1 to 128 is set using two rotary switches.
• Visibility from all directions: Dual alarm LEDs mean no specific mounting orientation is required.
• Unaffected by airflow: Measurement is unaffected by the speed of the ambient air.

Installation and Commissioning

The DT2063N is ceiling-mounted by fitting it to a 2000 series base. The address is set using the two rotary switches on the detector; since the dual LEDs are visible from all directions, the detector does not need to be installed in a particular orientation. The layout should be planned so that the coverage area remains below 80 m². Once the detector has been added to the panel, the fixed trigger temperature can be adjusted if necessary, and operation verified with a heat test. An isolator base is available as an option.

Frequently Asked Questions

What does A2R mean? In accordance with EN54-5, it indicates Class A2 temperature threshold detection combined with rate-of-rise (R) detection.

Can the alarm temperature be changed? Yes. The fixed trigger level can be adjusted via the panel for applications requiring a higher temperature.

Does the mounting orientation matter? No. The dual alarm LEDs are visible from all directions, so no specific mounting orientation is required.
