The DS-PDHT-E-WE is a wireless temperature detector, designed for integration into alarm systems, particularly the AX PRO series.
The detector does not detect smoke, but relies on the rise in temperature. It is suitable for environments where smoke may not be immediately detectable, but an increase in temperature is a clear indication of risk.
Detection Method: Temperature sensor. Alarm Activation Temperature: When the ambient temperature exceeds 57 °C. Power Supply / Battery: For sensor operation: Two (2) non-replaceable Energizer L91 batteries. For RF transmission: One (1) replaceable CR123A battery. Battery Life: ~10 years for the sensor when standalone, and ~5 years for the RF module. Transmission Method: Two-way RF communication, frequency 868 MHz. Transmission Security: AES-128 encryption. Transmission Range (open space): ~1.6 km. Sound / Alarm: Buzzer > 85 dB @ 3 m. Indicators / Interfaces: LED indicator (red when alarm is triggered). Additional Features: Self-health check, signal strength indicator. Operating Temperature: -10 °C to +50 °C. Dimensions / Weight: Diameter 120 mm, height 52.5 mm, weight 179.5 g. Installation: Ceiling mount, indoor use.
