Hikvision Wireless Carbon Monoxide Detector | DS-PDCO-E-WB
The Hikvision DS-PDCO-E-WB is a wireless carbon monoxide (CO) detector for indoor ceiling mounting. It sounds a built-in buzzer of at least 85 dB at 3 m and reports to the alarm panel over two-way 433 MHz RF wireless with AES-128 encryption, with up to 1 km range in free space.
Color: White

Carbon Monoxide Sensing: A dedicated carbon monoxide sensor watches the air around it. When CO is detected, the red alarm LED lights, the buzzer sounds locally and the alarm is sent wirelessly to the panel.
Loud Local Alarm: The buzzer reaches at least 85 dB at 3 m, so people nearby are warned on the spot. Alarm sound interlink is supported, as listed in the official datasheet.
Secure Two-Way Wireless: Two-way RF at 433 MHz with AES-128 encryption keeps the link to the panel protected, with up to 1 km range in free space. Enrollment is by power-up, remote ID or QR code.

Long Battery Life: The sensor runs on two non-replaceable Energizer L91 batteries rated for 10 years, and the RF wireless module uses one replaceable CR123A battery rated for 5 years. This keeps maintenance to a minimum.
Status Monitoring: Environment temperature and signal strength indicators plus a self-health check help the installer confirm a good location and keep the detector in working order.
Who it's for / Works with
The Hikvision AX PRO wireless alarm system (433 MHz -WB range). The control panel is sold separately.
Good to know
- Ceiling-mounted detector for indoor use.
- The sensor batteries are not replaceable; only the CR123A battery of the wireless module can be replaced.
