Alarm Lock 250 is an electronic panic lock that provides enhanced security and convenience for various types of doors. It features a durable construction with a US28 aluminum baked enamel finish, ensuring longevity and resistance to wear and tear. The lock operates on a 9VDC alkaline battery, providing a long battery life of approximately one year in standby mode and up to 200 alarm sequences or 7 hours of continuous alarm.

One of the key features of the Alarm Lock 250 is its dual piezo horn, which generates a loud sound pressure level of 95dB at a distance of 10 feet. This ensures that the alarm is clearly audible, alerting people in the vicinity in case of an emergency. The lock also includes a low battery detection system, providing timely notification when the battery needs to be replaced.
