Compact wireless alarm for doors and windows

The AmerTac SEC300 is a battery-powered magnetic contact alarm that sounds at 90 dB when a protected door or window is opened. It mounts with supplied tape and requires no wiring or tools. Three AG13 cells are included so the unit works straight out of the box.

Suitable for renters and homeowners wanting

This alarm suits anyone needing an immediate audible warning without subscription fees or smart-home integration. It is not for users who require remote notifications, activity logs, or integration with a wider security ecosystem.

90 dB magnetic contact trigger

The single deciding specification is the 90 dB siren activated by the magnetic reed switch when the gap between sensor and magnet widens. If that sound level and contact type match the intended opening, the SEC300 fits the requirement.

Questions about this item

When will the three AG13 batteries need replacing?

The three included AG13 batteries power the 90 dB alarm; replace them when the sound level noticeably drops.

What limits continuous operation if the alarm is triggered for a long period?

The 90 dB siren runs until the AG13 cells are depleted; battery life is the first limit under sustained activation.

Does the unit generate noticeable heat or noise while armed all day?

In standby it draws negligible power and is silent; only the 90 dB alarm sounds when the magnetic contact opens.
