Hikvision Wireless Heat Detector | DS-PDHT-E-WB
The Hikvision DS-PDHT-E-WB is a wireless heat detector for the Hikvision AX PRO alarm system. It raises an alarm when the ambient temperature exceeds 57 °C, sounds its own built-in buzzer and sends the alarm to the control panel over secure two-way 433 MHz wireless, with up to 1 km range in free space. It is a ceiling-mounted detector for indoor use.
Color: White
Key Features:
57 °C Heat Alarm: A temperature sensor monitors the room and triggers an alarm once the ambient temperature goes above 57 °C.
Built-in Buzzer and Standalone Function: The detector has its own buzzer (≥ 85 dB at 3 m) and a red alarm LED, so it gives a local warning on the spot as well as reporting to the panel.
Secure Two-Way Wireless: Two-way RF at 433 MHz with AES-128 encryption and up to 1 km transmission range in free space.
Long Battery Life: The sensor runs on 2 non-replaceable Energizer L91 batteries rated for 10 years, and the wireless module uses 1 replaceable CR123A battery rated for 5 years.
Easy Enrollment: Add it to the panel by power-up, remote ID or QR code. The detector also reports environment temperature and signal strength.
