DESCRIPTION OF PREFERRED EMBODIMENTS
'' '. .:
Referring now to the drawings, and more particularly to Figures 1 and 2, there is shown generally at 10, the portable, stand-alone alarm system of the present invention. As herein shown, the system is provided as a compact portable sealed housing having a first compartment 01 in which is housed an electronic alarm control circuit 40 (see Figure 3) and to which is connected various electronic ~components, as will be described later in detail with reference to Figure 3. A
second locked housing 03 is provided in which is housed a cellular telephone system as will be more specifically defined with reference to Figure 3. A third sealed , .
housing 02 is also provided and has a removable panel for ~ . :
~: access to the interior thereof. This third compartment : houses a transformer 43 and a rechargeable battery 42 (see Figure 3) and is connected to the alarm control ~ . :
circuit 40. A handle 15 is conveniently located on the .
: . . ;
~ housing for transportation purposes.

A digital key pad 11 is secured to the front : -wall 10' of the housing compartment 01 and has a , plurality of push button switches 12 to permit a person who is the proprietor of the alarm to program the control - ~
circuit 40 to accept an authorized user code which is ' .
stored in the memory of the control circuit 40. Both side walls of the housing, namely side walls 06 and 07, have perforated areas adjacent which are secured sirens 17 and 17'. A low temperature detector 20 and a heat detector 21 are also mounted in the side wall 06. One of these detectors or both can be secured to a transducer ~ . .
circuit 20' which can be switched into the circuit as an option to provide temperature monitoring signals to the control circuit 40 which could be stored in a temperature data storage circuit 60 for periodic transmission through the cellular telephone transceiver 46. An A.C.
connecting plug 24 and a D.C. connecting plug 22 and a pair of telephone jacks 18 and 19 are further secured to the side wall 06.
In the compartment 03, there is provided a cellular telephone 47 and a transceiver circuit 46 for , recelving and transmitting telephone signals. The telephone jack 18 also connects to a dialer circuit 66 . . .
provided in compartment 01 and also interconnects with the cellular telephone connection panel 45. The telephone system will automatically dial an alarm code to a designated remote control office to identify the code with the specific portable housing and the authorized user whereby to identify the location of the alarm. The other telephone jack 19 is provided to connect to a standard telephone as usually connected to a wall jack.

The antenna 16 is mounted on the top wall 04 of the compartment 03 and connects to the transceiver 46 as `
shown in Figure 3.
As shown in Figure 2, the compartment 03 has a back door 30 which is provided with a key lock 31 to provide access to a designated user person only so as to provide access to the handset 47 which is positioned inside the lock compartment 03. Although not shown, it is within the ambit of the present invention to provide a protection circuit whereby the key lock 31 can only be operated after a specific code has been punched in the . . .
key pad.
Secured inside the housing 02 is a transformer 43 to supply the necessary low voltage to the various component parts of the alarm control circuit 40. The transformer is connected to an electrical socket 24 in the side wall 06 of the housing. A power cord 36 is provided with opposed electrical end plugs 35 and 37.
Another electrical socket 22 is also provided for extra D.C. supply. A 12-volt D.C. rechargeable battery 42 is mounted inside the seal housing 02 and acts as an auxiliary supply in the event of a power failure. An actuator/detector power switching circuit 65 detects the local power supply failure and switches the system to the D.C~. rechargeable battery 42.
The receiver circuit 44 is a multi-channel receiver and is also provided in the housing 01 and interconnects with the control circuit 40. Each channel of the receiver is connected to the control circuit 40.
. .
To these channels can be programmed a motion detector operating at a frequency which is the same frequency as - 6 - ~ .-'` ~'';
~36~0 the receiver channel. Accordingly, a plurality of motion detectors can be provided. These motion detectors are infrared wireless detectors having built-in transmitters tuned to a respective channel of the receiver.
Accordingly, up to four detectors can be provided. It is also pointed out that a first one of these channels is connected to a delay circuit associated with the control circuit so that the control circuit will only switch to an alarm state to generate an alarm code on the cellular telephone line after a predetermined time delay.
Therefore, the detector associated with this channel is positioned in an area where the authorized user can enter to punch in a code on the key pad to deprogram the alarm within the set time delay period. The other channels have no delay circuit associated therewith and generate alarms as soon as they receive an alarm signal from their associated detectors.
The heat detector 21 as hereinshown is provided to sense a local fire condition. This detector 21 is connected to the control circuit 40 which switches to an alarm state when it receives an alarm signal from the . ..
detector and sends a fire identification signal through the cellular telephone system. The detector 18 as ~: :
hereinshown is a low temperature detector and senses a predetermined low temperature value. As previously ~ -~ , .
described, a transducer circuit 20' may be associated with one of these detectors to monitor a broad range of :. : .
temperature variations and provide signals to a remote -~
station or to a facsimile machine (not shown) identified by the dialer circuit 66 and operable at a remote location. Another feature of the present invention is '' :
~ ~) 3 ~ .5 ~
that by the use of a cellular telephone, it is also possible to interface the system with a computer system through a modem and to provide alarm conditions or temperature monitoring signals, as above described.
The digital key pad 11 is also provided with an annunciator LED display 14 to indicate various functions such as an indication that the power is on, an indication of open zones, the condition of an internal circuit, a local problem, the condition of the alarm memory circuit, etc. The fuses 41 are provided inside the housing and protect the internal circuits against high voltage surges.
It is within the ambit of the present invention ~ -;to cover any obvious modifications of the preferred embodlment described herein, provided such modifications fall within the scope of the appended claims.
