The Yale HSA App Enabled Alarm Kit provides a smart and expandable home security solution with app-enabled control and no monitoring fees. This wireless system can be expanded to include up to 20 accessories, offering a 30m range and the ability to part-arm for zone control. The kit includes 1x HSA Alarm Hub, 1x Siren, 1x Dummy Siren, 1x Remote Keypad, 2x PIR Motion Detectors, 1x Door/Window Contact, batteries, and fixings. The system allows for easy installation and simple use, with components that are pre-linked and wireless. System alerts are sent via email, text, and app notifications when the alarm is triggered. The kit is compatible with Yale HSA-Alarm accessories and comes with a 2-year guarantee. The alarm can be controlled remotely via the portable keypad or the smartphone app, allowing users to part or fully arm the system. Alerts are triggered by motion detection, with a 10-second window to enter a valid PIN before the 100dB alarm sounds. The system features a keypad for local operation by non-smartphone users, part-arm functionality for security while at home, and works with Philips Hue for visual deterrence via the dummy siren. A hub features battery backup to ensure continuous operation during power outages. The system operates on a 433MHz frequency.
