Smart Motion & Door Sensors

This page holds smart door, window and glass sensors: magnetic contacts that report a door or window opening, glass-break detectors and shock sensors. Ajax supplies wired Fibra and wireless Jeweller DoorProtect contacts and GlassProtect detectors, and Pyronix wired and wireless shock sensors, including a magnetic contact with a shock sensor. Hikvision adds a wireless PIR and glass break detector, and Texecom a Grade 3 wired shock sensor.

Choosing Smart Motion & Door Sensors

Decide between wired and wireless first, then what the sensor has to detect.

Door and window contacts

The Ajax DoorProtect U Jeweller 121293.03.WH1 is a wireless contact with a pre-installed CR123A battery, typical battery life of up to 7 years and a radio range of up to 1,200 m in open space. The black 121294.03.BL1 needs an Ajax Hub, sold separately, and the Superior DoorProtect Jeweller 133194.03.WH1 comes with two magnet sizes. For a wired system, the DoorProtect Fibra 44393.03.WH1 has two reed switches, so the magnet can sit left or right, and it needs a compatible Ajax Fibra hub.

Contacts with shock detection

The DoorProtect Plus Fibra adds shock and tilt sensing to a wired contact, with three levels of shock sensitivity and a tilt threshold set between 5° and 25°, and its Fibra line reach is up to 2,000 m over U/UTP Cat.5. On Pyronix systems, the MC1Z2/SHOCK-WE combines a central magnetic reed contact with an accelerometer shock sensor and has two zone inputs. It works with Enforcer, or with EURO through a ZEM.

Shock sensors

The Pyronix NANO/SHOCK-WE is a compact wireless shock sensor that fits within uPVC window or door frames, with pin-hole sensitivity calibration, LED indication and up to 2 years of battery life. Wired options include the Pyronix SHOCK/W, a piezo electric sensor with adjustable sensitivity, latch and reverse polarity protection, and the Texecom AEL-0001 Impaq S G3, certified to EN 50131-2-8 Grade 3, with five selectable digital sensitivity settings and built-in EOL resistors.

Glass-break and PIR

Each Ajax glass-break detector here has a 9 m detection range with about 180° of horizontal coverage, and uses the DualTone algorithm to reduce false alarms. The GlassProtect Fibra is wired, while the GlassProtect S and GlassProtect U are wireless Jeweller devices with a pre-installed CR123A battery. The Hikvision DS-PDPG12P-EG2-WE combines a 12m PIR with an 8m glass break sensor and pet immunity up to 30kg.

Frequently asked questions

Can a door contact work as a door chime?

Yes, some door contacts have a chime function that works through a paired siren while the alarm is disarmed. The Ajax DoorProtect Fibra and DoorProtect Plus Fibra have chime capability when paired with an Ajax siren, and the DoorProtect Fibra can act as a doorbell when the system is disarmed. They also take one third-party normally closed wired detector, which needs its own power.
