2) SIRENS Position one siren in the rear of the caravan next to an air vent and angle so as to allow the sound to travel to the outside.Position the second siren in front gas box (a hole may have to be cut in the floor to allow the sound to exit) if this is not possible position the second siren in the front bedding box in the same way as siren one.

3) PRESSURE MATS These have to be positioned under the carpet one in the main area and one near the door area (see layout diagram) Their are a number of ways of achieving this, a) in some caravans the furniture can be unscrewed from the floor and the carpet lifted to gain access.

b) cutting the carpet close to the furniture. Care should be taken when doing this so that when refixing the carpet no signs of cutting are visable. (Refix carpet by means of staples or adhesive tape) 4) MAGNETIC SWITCHES One pair for the main door and one pair for the gas locker.

position the blank switch on the door and the other containing electrical screws to caravan wall.

these should be positioned no more than 5-lOmm apart (see fig 1) FIG 1 5-lOmm

Press the remote key, the side lights will flash three times,wait 60 seconds then open the door, the alarm will activate.Switch off by pressing the remote key, the side lights will flash once.

Test 2 Repeat above procedure for the locker box.

Test 3 Stand inside the caravan with the door closed and press the remote key. Wait 60 seconds, then walk onto the carpeted area the alarm will activate. Switch off with remote key.

TEST 4 Making sure all doors are closed press the remote key. Wait 60 seconds, insert winder handle into winder. Contact between winder handle and under floor switch will activate alarm.

Switch off with remote key Having completed the above tests the alarm should now be ready for use If you have installed this alarm according to the instruction guide you should not have any problems. If you do contact D.C ALARMS on their HELPLINES 0634-377365 or 0795- 539354.

DESCRIPTION PR2000 CARAVAN SECURITY SYSTEM This invention relates to a caravan security system.

Caravan security systems,of which there are very few at the present time, are designed to prevent theft by means of movement and entry.

These systems use certain well known anti movement switches primarily mercury tilt and pendulum activated devices.

They also use entry detection devices eg Passive infra red,ultrasonic and magnetic switches.

These systems are prone to false alarm when no entry has been effected. Weather conditions eg on windy days small draughts of air entering the caravan will cause the alarm to activate as the system is unable to distinguish between air movement or a physical prescence.

These systems which rely on passive infra red, ultrasonic sensors,or magnetic contacts to all points of entry, require large cable runs which are very difficult to conceal.

According to the present invention there is provided a security system not prone to false alarm. A newly developed anti movement switch with no moving parts and entry detection by means of pressure operated pads positioned under the floor covering,produce a system not affected by air movement.

Caravan door and external locker box apertures are protected by magnetic contacts.Cable run is greatly reduced and easily concealed at floor level.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying installation guide in which: Page 1 lists the necessary parts required to build the system.

Page 2 shows a suggested layout Pages 3-7 show how to install and connect up the system.

Page 8 shows how to test and commission the system.

Referring to the installation guide the system comprises all parts listed on page 1 and is laid out according to page 2.

eg:- one siren in the front and one in the rear of the caravan to effect the maximum sound output possible The control unit to be sited close to the caravan fuse block for ease of connection to caravan loom.Pressure operated pads installed under the floor covering to detect physical prescence and magnetic contacts to detect unauthorised entry through the door or locker boxes.
