Key Features:
• A visible deterrent to opportunist thieves
• Making a noise to scare off an intruder
• Waking you up if you're at home and someone tries to break in
• Making neighbours aware of a break-in
• These are also known as non-monitored or bells-only alarm systems.
You set your alarm by entering a code. Or some systems provide one or more fobs to go on your key ring. You swipe them against the control panel instead of typing on the keypad. To deactivate the alarm you enter the code again or swipe the fob.
When the system is activated by an intruder, it will trigger sounders that are mounted inside and on the external walls of your building. A strobe light on the external sounder will flash as well.
To stop the noise and the flashing strobe, someone needs to enter the correct code or swipe the fob. The external sounder will only continue for a maximum of 20 minutes. This limit is to prevent noise pollution – we've all cursed that annoying alarm that doesn't stop in the middle of the night! The internal sounder and outdoor strobe light will continue to flash until the system is turned off.
Pros:
The loud noise and attention it attracts is likely to scare off a chance intruder.
There's a minimum service charge or running cost once you've bought and installed the system.
Battery back-up in external sounder means it keeps ringing even if the mains connection or cable to it is cut.
Cons:
This is the bare minimum of protection: if nobody responds to the noise any burglar can carry on ransacking your property!
Seasoned burglars can remove external sounders from the wall and immerse them in a bucket of water to stop the sound.
