Scantronic DET-2R-DC | Wireless Door Contact | Slimline, Grade 2, White/Brown/Grey

FAQs

What is the difference between the DET-2R-DC and other models in the range?

The DET-2R-DC is specifically a door and window contact detector using magnetic technology. The DET-2R-S features an accelerometer for shock or movement detection, while the DET-2R-SDC combines both technologies, providing dual protection with both door contact and shock detection capabilities in a single device.

How long does the battery last in the DET-2R-DC?

The DET-2R-DC provides a typical battery life of 3 years using a single CR2 lithium battery. This is longer than the shock sensor variants due to the lower power consumption of magnetic contact technology, with the detector drawing just 3μA in quiescent mode. The system provides a low battery warning at 2.4Vdc to allow proactive replacement before the battery is depleted.

What is the maximum distance between the detector and the control panel?

The DET-2R-DC has a radio range of up to 600m in free space. However, actual range will be affected by building construction, walls, metal structures, and other environmental factors. In typical residential installations, expect ranges of 50-100m depending on building materials. For longer distances or difficult environments, wireless expanders can be used to extend coverage.

Can the DET-2R-DC be used outdoors?

The DET-2R-DC is rated as Environmental Class II, which means it is designed for indoor use with an operating temperature range of -10°C to +55°C and humidity tolerance up to 95%. While it can tolerate some exposure to cold or damp conditions, it should not be installed in fully exposed outdoor locations subject to direct weather. For outdoor perimeter protection, consider installing it in sheltered locations such as covered porches or garages.

What colour options are available?

The DET-2R-DC is available in three colour finishes to suit different installation environments: white (DET-2R-DC-W), brown (DET-2R-DC-B), and grey (DET-2R-DC-G). All variants maintain the same slimline housing dimensions and technical specifications, with colour selection purely aesthetic to blend with door frames, window frames, or interior décor.

Is the DET-2R-DC compatible with older Scantronic systems?

The DET-2R-DC uses Scantronic Secure Radio (SSR) technology operating on 868-868.5MHz, which is compatible with current generation Scantronic control panels including the 80HE, 100WE, 200WE, and 400WE models. It also includes legacy mode support at 868.6625MHz for backward compatibility with some older Scantronic radio systems. Check your specific control panel model documentation to confirm compatibility.

How is the DET-2R-DC different from a wired door contact?

Unlike wired door contacts, the DET-2R-DC requires no cabling between the detector and control panel, making installation faster and less invasive. It uses two-way radio communication with signal encryption for security, provides over-the-air firmware updates, and includes features like low battery warnings and LED identification. However, it does require periodic battery replacement, whereas wired contacts draw power from the control panel.
