Overview
Hardwired magnetic contact or reed switch — wired door/window loop for VISTA, Challenger DGP, Reliance, or commercial panel inputs (1035/1045/2200/2500 series, Sentrol reeds).
On Interlogix systems, wireless devices are supervised zones on the panel — tamper, low battery, and missing signals appear as trouble conditions that may block arming depending on panel programming.
At a Glance
| Specification | Details |
|---|---|
| Detection | Open/close magnetic circuit |
| Wiring | Normally closed loop with EOL supervision |
| Install | Surface, recessed, or industrial wide-gap models |
| Use | Hardwired panel zones — not TX-E wireless |
What This Device Does Well
Provides reliable supervised status at the panel and Alarm.com / UltraSync when installed, enrolled, and range-tested correctly.
Before You Service or Replace One
- Sensor SKU — TX-E wireless vs hardwired loop vs 433 MHz expander path.
- Panel online — resolve panel AC/comms trouble before blaming sensor.
- Range — 433 MHz expander or move wireless receiver for distant zones.
- Battery type — use listed cell; replace all batteries in multi-cell devices.
- Tamper — cover fully closed before declaring hardware fault.
Official Sources
Use official Aritech install PDFs and install guides for exact wiring, enrollment, and firmware — specifications vary by SKU and region.
Installation Notes
Follow Magnetic contact install datasheet and the official resource links in this product folder for mounting, wiring, and enrollment.
Pre-install checklist
- Confirm panel model (Simon/Challenger/Reliance/Tecom) and encryption requirements.
- Verify dealer cell account and module SKU before cell install.
- Document installer code and existing zone map for takeover jobs.
- Plan antenna routing (ANT5XL) when panel location has poor cell RSSI.
- Have listed batteries and tools for sensor mounts before enrollment.
Typical install sequence
- Mount and power panel; apply firmware updates per dealer bulletin.
- Install cell module and run communication test / Alarm.com / UltraSync activation.
- Enroll wireless sensors via installer Learn mode; label zones.
- Include Z-Wave devices after excluding from any prior hub.
- Install 433 MHz expander or optimize receiver placement before fringe wireless sensors.
- Run walk test, user code training, and central station test if monitored.
Magnetic contact alignment
- Gap between sensor and magnet must be within spec — too wide reads open.
- Use spacers on uneven trim; verify tamper clears when cover closed.
- For encrypted TX-E sensor, enroll on Simon learn mode support enabled.
