The DOOR GUARD ALARM is
a very versatile vibration alarm. Ideal
for home, office or travel. This alarm
requires no installation, simply hang
it on any doorknob and it instantly
detects any vibration. When the
alarm is tripped, it will emit a 98 dB
alarm for 20-30 seconds, then will
reset in 3-5 seconds. The sensitivity
of the alarm is easily adjusted with a
screwdriver.
The Door Guard can also be used
as a flashlight. The Door Guard is
ideal for keeping you and your loved
ones safe from harm whether in your
home or while you travel. Not sure
about that shady looking hotel, but
can’t beat the price? Now you can
feel confident and safe. Uses 2 AAA
batteries (not included).
