The grade 3 TMD15 detector combines a dual tech detector and a PIR sensor in a single housing. Featuring 15m volumetric coverage, it offers outstanding detection performance designed to meet the latest industry regulations. The detector responds to environmental changes by automatically adjusting its levels of immunity to background disturbances, thanks to its patented Independent Floating Thresholds.

Key Features
  • 15m, 90° volumetric coverage
  • Non-overlapping fields of view
  • Confirmation detector

Product Features

Confirmed Dual Technology & PIR Grade 3 Detector

Based on Pyronix tried and tested patented technologies, the TMD15® offers outstanding detection performance with optimum reliability designed to meet the latest industry regulations.

TMD (sequential confirmation) mode

Two independent detectors in one housing featuring non-overlapping fields of view and separate relay outputs provide a simple solution to sequential confirmation.

Anti-masking detection

Ideal in high security environments where there may be a significant risk of masking.
An area immediately in front of the TMD15 is monitored continuously and separately from its normal mode. Any intrusion into this area activates the anti-masking process.
TMD15® also has separate mask and trouble output reporting.

Digital Temperature Compensation

When the product is used in a hot environment this technology digitally adjusts the detector’s sensitivity. This enables it to maintain its range even when the background room temperature is almost equal to the external body temperature of 34ºC (internal body temperature = 37ºC).

Selectable EOL resistors

The detector incorporates selectable alarm resistor values of 6K8, 5K6, 4K7 and 1K and tamper values of 5K6, 4K7, 2K2 and 1K catering for most control panels on the market. Voltage free relays allow for fitting of alternative resistance values not inherently supported by the device.

Patented Independent Floating Thresholds (IFT)

This technology, patented by Pyronix, allows the detector to respond to environmental changes by automatically adjusting its levels of immunity to background disturbances.

Anti Blocking Technology

Provides blocking detection up to 15m in disarmed mode, for example, if the field of view is blocked when the system is being armed, arming will not be possible until the blockage has been removed.

Tricover mode

Triple coverage ensures that an alarm will not occur unless all three detector fields are activated in a particular sequence. Offers unparalleled stability in the elimination of false alarm activations.

Auto sensitivity feature

Depending on the environmental conditions, the detector will automatically adjust its sensitivity.

Volumetric coverage

15m Volumetric coverage in both PIR lenses. Ideal for hostile environments.
