The Hikvision DS-PS1-I-WE is a wireless indoor siren designed for the AX PRO Series alarm system. It features 868 MHz two-way wireless communication with Tri-X protocol, AES-128 encryption, and frequency hopping to ensure secure, reliable transmission over a 1.6 km range in open space.

The siren produces 90 to 110 dB with three distinct alarm sounds (fire, panic, intrusion) and includes a configurable LED indicator (red or blue) for visual alerts.

Fully configurable via the Hik-Connect app, it supports multiple enrollment methods (power-up, remote ID, QR code) and easy installation. Powered by a single CR123A battery, it offers up to 3 years of battery life (based on 90 seconds of activation every two weeks).

The device includes front and rear tamper-proof protection and constant connection monitoring, with immediate notifications if the signal is lost.

It operates in temperatures from -10°C to 55°C, with 10% to 90% humidity (non-condensing), and has dimensions of 88 x 88 x 32 mm, weighing 170 grams. Its discreet design blends seamlessly into indoor environments.
