This effective Entry Alarm with RF Remote Control is great for guarding a door
or window from entry. The alarm can be conveniently activated from the remote
control. The three different radio frequencies allow you to arm and disarm
multiple units in your house with one click of the remote. Alternatively you can
tune the channel of the remote to operate different sets of units within your
house.
You can easily customize your wireless alarm. Just install the main unit
and the magnetic bar on the frame of the door or window, using the powerful
adhesive tape. When the door or window is opened the alarm will emit an intense
110dB siren. This is a very economical way to keep someone out of someplace you
don't want them to be, or alert you of their presence. Main unit uses 3AA
batteries (not included). Remote uses 3 LR44 batteries (included).
