Description

The Ajax DoorProtect (8EU) ASP Black is a battery-powered door and window contact sensor. It uses a reed switch to detect when a door or window is opened, and it communicates wirelessly with the Ajax system over the Jeweller protocol.

The set includes a small magnet and a big one. The detector also has a terminal for connecting an additional wired detector with a normally closed (NC) contact. It is housed in a black case, and a white version is also available.

Key features:

  • Detection: 1 reed switch, with vibration protection that ignores vibrations lasting up to 0.15 s
  • Wireless: Jeweller (Ajax) protocol with a communication range of up to 1200 m (3937 ft), GFSK modulation and block encryption with a dynamic key
  • Tamper protection and device authentication, with connection loss detected after 36 s
  • Power: 1 × CR123A battery with a battery life of up to 7 years
  • Operating conditions: -10 … +40 °C (14 … 104 °F), humidity up to 75%, IP50 protection
  • Size and weight: detector 3.54″ × 0.79″ × 0.79″, weighing 29 g (1.02 oz)
  • Additional input for a wired detector with a normally closed (NC) contact
