Ajax Electric Fence Kit
From: R714.00 Incl. VAT
Receive electric fence alarm alerts and control your energiser through the Ajax app. This integration kit connects a compatible electric fence energiser to your Ajax security system. The components are wired to the energiser and communicate wirelessly with your Ajax Hub.
- Remote arming/disarming: The Ajax Relay operates the energiser’s compatible on/off control circuit, allowing you to switch the fence on or off through the Ajax app.
- Fence alarm notifications: The single-pole relay connects the energiser’s alarm output to your chosen Ajax device. When the fence alarm triggers, alerts are sent to system users and your linked armed response provider where monitoring is enabled.
- Choose one alarm device below: Select Ajax DoorProtect for fence alarm alerts, or Ajax Transmitter for fence alarm alerts plus optional enclosure tamper monitoring.
- Optional enclosure: Add the weather-resistant enclosure where the integration components require additional protection.
Please note: A compatible Ajax Hub and electric fence energiser are required and are not included. Tamper monitoring requires a compatible tamper switch to be fitted and connected.
