Ajax DoorProtect Plus

DoorProtect Plus Jeweller: for doors, windows, and the vault that won't wait for a break-in to finish

Everything in the standard DoorProtect, plus a built-in accelerometer that catches what a reed switch alone would miss: a door being forced, a vault being pried, or a window left cracked for air that gets pushed the rest of the way open. The shock sensor has three adjustable sensitivity levels and can be set to ignore a single bump, so a slammed door down the hall won't trip a false alarm, but a real forcing attempt will.

Tilt detection is built for windows left in airing mode: set the trigger angle anywhere from 5° to 25°, and the delay before an alarm fires anywhere from 1 second to 1 minute, matched to how the window actually gets used.

Same reed-switch reliability as DoorProtect (two magnet sizes, plastic-capsule protection against drops), but the added electronics mean the pre-installed battery runs up to 5 years instead of 7. Wireless range and encryption are unchanged: up to 1,200 m (3,900 ft) over Jeweller's encrypted two-way link, with instant tamper reporting and full remote configuration.
