Honeywell 5816WMWH — Specs & Hong Kong Installation
Honeywell 5816WMWH wireless door/window contact for metal gates, aluminium windows, and internal doors common in Hong Kong.
Best for: Entry-point protection
Product overview
The 5816 wireless contact is one of the most-used sensors on our residential jobs. It reports open/close status for gates, windows, and cabinets without running new cable through finished walls.
We select magnet spacing carefully on thick metal gates and verify RF supervision so a dead battery does not go unnoticed.
