Ajax DoorProtect - Wireless Magnetic Contact - Black

Discreet and Trusted Perimeter Protection Against Intrusions The Ajax DoorProtect Jeweller in black finish is the staple wireless magnetic contact optimized to blend seamlessly into residential or commercial architectural spaces showcasing dark-painted frames, iron gates, or modern sombre-toned window profiles. Forming the crucial first line of defense within your security ecosystem, this device reacts instantaneously within milliseconds when the magnet separates from the sensor main body. Its durable physical architecture features a premium mechanical reed switch array, field-tested to sustain over two million operations without losing structural responsiveness.

Flexible Installation Metrics and Advanced False Alarm Immunity Device deployment flexibility over dark frames is heightened by the inclusion of two distinct black magnets in the standard retail pack: a large magnet, tailored for heavy doors or wide frames showing significant alignment tolerances (operating gap up to 2 cm), and a small magnet, perfect for thin window profiles or PVC structures where physical space is limited (operating gap up to 1 cm). Furthermore, DoorProtect incorporates a smart digital signal filter that parses raw mechanical switch data, easily dropping short vibration noise caused by wind gusts, thereby removing false alerts.

Zone Expansion Framework and Encrypted Radio Link On its back frame, the unit hosts a dedicated physical auxiliary input terminal block supporting normally closed (NC) dry contacts. This integration tool enables installers to hardwire a secondary third-party peripheral — such as a heavy roller-shutter contact or an emergency panic button — grouping and routing telemetry signals smoothly through DoorProtect's integrated wireless radio antenna. All network communication with the central Hub is locked down via the proprietary Jeweller protocol, showcasing automated frequency hopping against jamming and polling rates scalable down to 12 seconds.
