Overview
The SABRE HS-DSA is a battery-powered door wedge that combines physical door blocking with a 120dB alarm siren, meant as a no-install security layer for rentals, dorms, hotel rooms and apartments. It suits anyone who wants a loud, portable alarm rather than a wired home security system.
The gap requirement of 7/8 inch between floor and door, plus the fact it needs a 9V battery not included, are worth checking before buying, and it is a manual-reset alarm, meaning it keeps sounding until switched off rather than stopping once the pressure releases.
- 120dB siren audible up to 1,500 feet away
- Non-skid pad resists the door being pushed open
- Battery-operated, no wiring required
- Compact size built for travel
Who it's for
Good for travelers, renters and dorm residents who want a cheap add-on alarm for a door with no wiring or installation. Less suited to households with dogs or kids who might bump it, since it does not silence itself once triggered.
Pros and cons

- Alarm does not auto-reset, you switch it off manually
- Requires a 9V battery not included in the box
- Weaker grip on smooth floors like wood or tile
