Overview
This TECKNET set puts 3 magnetic door and window alarms in one box, each offering a 2-in-1 alarm and chime mode with 3 levels of volume control. Like other entry sensors in this category it mounts with adhesive tape, aimed at doors, pools, cars, sheds and caravans.
The main difference from a single on/off switch design is the 3-level volume control, which lets you dial the alert down for a quieter chime or up for a louder deterrent instead of one fixed loudness. The 36-month warranty here requires product registration to activate, which is easy to miss at purchase. Installation is adhesive tape only, with a stated 0.5 inch mounting tolerance from the alarm's arrow side.
- Pack of 3 magnetic door and window alarms
- 2-in-1 alarm and chime with 3 volume levels
- Peel-and-stick adhesive mounting
- 36-month warranty with registration
Who it's for
Works for anyone wanting more than one entry point covered from a single pack, and who wants to tune alert volume rather than accept one fixed level. Skip it if you specifically want a smart or app-connected alarm.
Pros and cons

Performance notes
Each unit pairs an alarm body with a magnetic sensor; once the two separate by more than about 0.78 inches the alarm sounds, with 3 volume levels to choose from and a chime-only mode for a softer alert. Mounting is a tear-off adhesive sticker, and the maker specifies keeping the sensor within about 0.5 inches of the alarm's arrow side for reliable triggering.
