Product information

Description

Ajax 000001135 is a compact wireless magnetic door and window opening detector in black, designed to detect opening events using a reed (magnetic) contact. Intended for use with Ajax security systems, the detector provides discrete perimeter monitoring for homes and small commercial objects, connecting wirelessly to the Ajax Hub and triggering alerts when the contact separates. The device includes two magnets and a pre-installed CR123A battery.

Advantages

The detector offers long-range wireless communication up to 1,200 meters in open space and supports connection to third-party detectors via uartBridge and ocBridge Plus. It uses authentication, encrypted signals and frequency-hopping to protect against interference and fraud, and features a tamper-resistant body. British-made reed switches ensure mechanical reliability for over 1,000,000 cycles, while two-way communication with Ajax Hub allows periodic testing and remote configuration. Power consumption is optimized according to distance from the hub for a battery life of up to 7 years when pinging once per minute.

Suitable for

  • Residential doors and windows
  • Small offices and commercial premises
  • Perimeter protection in multi-floor buildings
  • Integration with Ajax Hub or third-party systems via bridge modules

Key specifications

  • Mounting: Surface-mounted (SmartBracket)
  • Distance to magnet: Up to 1 cm (small magnet), up to 2 cm (big magnet)
  • Detecting element: Reed switch
  • Additional wired input: Available
  • Tamper protection: Available
  • Radio power & protocol: 20 mW, Jeweller (868.0–868.6 MHz)

  • Battery life: Up to 7 years (ping once per minute)
  • Operating temperature: 0°C to +50°C
  • Operating humidity: Up to 80%
  • Dimensions: 20 × 90 mm

How to use

Mount the main unit and magnet on the door and frame using the SmartBracket mounting plate — there is no need to disassemble the body for installation. Position the appropriate magnet so the gap between magnet and detector does not exceed the specified distance (1 cm for the small magnet, 2 cm for the big magnet). Connect the detector to the Ajax Hub with a single click in the Ajax app; the connection quality and detection area can be tested remotely. If required, connect external wired detectors to the additional input and integrate third-party devices via uartBridge or ocBridge Plus.

Usage recommendations

Install the detector indoors within the specified temperature and humidity ranges, place magnets aligned with the detector to ensure reliable contact detection, and perform regular remote tests via the Ajax Hub to verify battery status and communication quality.
