Hikvision Bidirectional Wireless CO Detector for AX Pro

Tri-X bi-directional 868MHz wireless technology; RF range: 1600m (open space); CO sensor. >Multiple enrolment methods: Power on, remote identification, QR code. SSI (Signal Strength Indication); Fully remote configuration via APP; Battery type: Non-replaceable Energizer L91 x 2 for sensor. Replaceable CR123A x 1 for RF wireless. Battery life: 10 years. Supports cross-link function. Ceiling mount only.

The DS-PD451SMK-WE detector combines two forms of protection in a single device: photoelectric smoke detection and heat detection. It is a wireless, ceiling-mounted unit that communicates with the Hikvision AX PRO alarm control panel. When triggered, it alerts the system and occupants to the onset of a fire.

Dual detection: photoelectric smoke and heat
Fixed-threshold heat alarm (triggered above 64°C)
Rate-of-rise heat alarm (increase of more than 10°C per minute)
868 MHz wireless connection with a range of up to 1,000 meters from the hub in open space
AES-128 communication encryption
Up to 4-year battery life using two replaceable CR123A batteries
10-year sensor lifespan
Indoor ceiling installation
Available in black and white
Multiple enrollment methods: power-up, remote ID, QR code

The DS-PD452SMK-WE is a triple detector—combining smoke, heat, and carbon monoxide (CO) detection—with a 3-year battery life.
Powered by two CR123A batteries, it offers up to 3 years of operation, featuring secure AES-128 wireless transmission on the 868 MHz band and a range of up to 1,000 meters (open field) to the control panel or a compatible repeater.
It triggers an alarm based on a fixed temperature threshold exceeding 64°C or a rate-of-rise threshold exceeding 10°C per minute; the CO detection function monitors cumulative exposure, triggering an alarm starting at 50 ppm within specified timeframes.
