Alarm / Siren Unit — AS626 functions as an external siren/alarm accessory used together with access control or security systems (rather than as a standalone biometric reader or controller).

12 V DC Operation — Designed to be powered from standard 12 V DC supply lines commonly used in security systems.

Audible Alarm Output — Delivers a loud siren sound to alert occupants or nearby persons during unauthorized access or alarm-trigger events. 

Accessory for Access Control Systems — Typically used as part of a larger system (locks, sensors, controllers) to provide audible alerts — not for authentication itself.

Compact & Wall-Mountable Housing — Designed for easy installation in typical security installations (walls, enclosures, near control panels).

Tamper / Emergency Alert Ready — When integrated properly, can offer immediate alert on forced entry or breach detection — boosting overall security response.

Cost-Effective Safety Enhancement — As an accessory siren/alarm rather than a full-blown biometric device, AS626 adds audible security at lower cost, useful for small offices, shops, or residential installations with access control systems.
