Portable Alarm

BE AWARE OF THE INTRUDER BEFORE

 HE ENTERS THE PREMISES!

This simple to operate portable alarm system automatically activates

a highly pitched alarm sound if any outside leading DOORS or WINDOWS of

 the premises are OPENED, TAMPERED with, or BREACHED

IDEAL FOR 

HOMES - OFFICES - MOTEL/HOTEL ROOMS - CARAVANS

How does it work?

It detects low-level subsonic sounds (infrasonics - below the threshold of human hearing)

created by the movement of air. Unlike passive infra-red alarms, this alarm will not be activated by animal or

human movement in a room. Once activated, and after setting up for a particular environment, all can move

freely about the premises without the alarm going off - until an outside leading window or door is opened (or

tampered with). A window or door may be left partially open, but if it opened any further or closed, the alarm

goes off!  It is particularly sensitive to glass breaking, no matter how silently it happens!

It is no good having an alarm that sounds when the intruder is IN the house! The

 Infrasonic Portable Alarm will sound BEFORE access is gained!

Think again! What security do YOU have if the back-up battery of your fixed wired

security system is depleted after an extended power outage?

THIS ALARM IS NOT A GIMMICK!

IT CANNOT BE  PURCHASED AT A FLEA MARKET!

THIS IS A GENUINE ALARM SYSTEM!
