Abstract

A simplified, home-improvement-type, low voltage security system to prevent infants from entering the swimming pool area by monitoring the exit doors of a home leading to the swimming pool and the swimming pool by combined passive and active motion detectors and an alarm. Photoflood lamps can be added to the security system.

Claims

1. A low voltage security system devoid of computerized control for securing a backyard swimming pool and exit doors of a home and installable by a homeowner consisting of:

a low voltage electrical circuit containing;

at least two combined passive and active motion detector means positioned to each cover the swimming pool and exit doors of a home leading to said swimming pool with overlapping coverage, wherein at least one said motion detector means is a backup for another said motion detector means;

said at least two combined passive and active motion detector means directly connected to a transformer means which converts alternating current house voltage to a low direct current voltage for energizing said at least two combined passive and active motion detector means;

alarm means; and

a plug means which connects said transformer means to said house voltage; and

a plurality of photoflood lamps, whereby upon activation by the at least two combined passive and active detectors, illuminate the pool and exit doors;

whereby an intrusion to the backyard swimming pool and exit from exit doors can be detected by said at least two passive and active motion detector means and activates said alarm means and said plurality of photoflood lamps to alert any occupants of the house of the impending danger of intrusion, and said low voltage security system being installable by the homeowner and being devoid of computerized control.

2. The low voltage security system according to claim 1, wherein the low voltage is no more than 14 Volts D.C.

3. The low voltage security system according to claim 1, including an in-line switch in said electrical circuit.

4. The low voltage security system according to claim 1, including a plug-in timer inserted in said electrical circuit.

5. The low voltage security system according to claim 1, including an alarm means located outside the home.

6. The low voltage security system according to claim 1, including an alarm means located inside the home.

7. The low voltage security system according to claim 1, including alarm means located outside and inside the home.

8. The low voltage security system according to claim 1, wherein said at least two combined passive and active motion detector means are operative to produce passive infrared energy and active microwave energy.

9. The low voltage security system according to claim 1, wherein said at least two combined passive and active motion detector means each has an adjacent backup battery.

10. A method of securing a backyard swimming pool and exit doors of a home form intrusion with a low voltage security system devoid of computer control and installable by a homeowner consisting of:

providing at least two combined passive and active motion detectors positioned to each cover an area comprising the backyard swimming pool and exit doors of a home leading to said swimming pool with overlapping coverages,wherein one motion detector is a backup for the other detector;

providing a low voltage source to energize the at least two combined passive and active motion detectors;

providing an alarm which is activated when the at least two combined passive and active motion detectors detect an intruder entering the covered area; and

providing a plurality of photo-floodlamps in the swimming pool area, said photo-flood lamps being activated by said at least two combined passive and active motion detectors detecting an intruder;

whereby a homeowner is alerted to the intrusion into the swimming pool area and the exit doors of the home by the alarm and the illumination from the photo-floodlamps, and which low voltage security system being installable by the homeowner and being devoid of computer control.

11. The method according to claim 10, wherein the low voltage source provided is not more than 14 Volts D.C.

12. The method according to claim 10, wherein an in-line switch is provided to operate the at least two combined of passive and active motion detectors.

13. The method according to claim 10, wherein a plug-in timer is provided to operate the at least two combined of passive and active motion detector, whereby the hours of operation can be programmed.

14. The method according to claim 10, wherein the alarm is located outside the home proximate to the swimming pool area.

15. The method according to claim 10, wherein the alarm is located inside the home to alert an occupant of the home.

16. The method according to claim 10, wherein the alarm includes alarm means located outside the home proximate to the swimming pool area and alarm means located inside the home to alert an occupant of the house.

17. The method according to claim 10, wherein the at least two combined passive and active motion detector are operative to produce passive infrared energy and active microwave energy.

18. The method according to claim 10, wherein the at least two combined passive and active motion detectors are operative to detect infants entering the swimming pool area from the exit doors of the home.
