Smart Alarm

This is a project to add additional ‘smart’ functionality into a thirty year old (1993) but fully functioning (and reliable) alarm system.

Existing alarm system

Gardiner Gardtec 800 series alarm, powered by 240v stepped down to 12v DC. With LED and LCD extension display/key pads.

4 wire detectors and 8 zones - with Texecom dual technology PIRS, a magnetic switch and a shock detector. Bell/Strobe unit and extension speakers.

“Smart” functionality added

Set and Unset of alarm using a remote control or via a keycode entered into a local (for security reasons) webpage. The webpage is accessible when outside the LAN by using a VPN server running on a Raspberry Pi. The webpage is redirected from a local domain (alarm.domain.com).

Live status of system (unset, set or alarm triggered) via the internal LED, a webpage and an email notification.

Remote updateable of firmware using Elegant OTA.
