Abstract

An auxiliary alert process and system thereof for alarm system are adapted for monitoring all the devices, so that a great amount of installation fee and equipment cost can thus be saved, wherein the auxiliary alert process which includes the following steps. (1) Maintain at least a sensor installed at an entrance or an exit of an existing alarm system in functioning condition when the alarm system is disarmed. (2) Monitoring the entrance/exit by the sensor to determine whether there is a motion occurred at the monitoring entrance/exit. (3) Send a detected signal to a security control device which is connected between a control panel and the sensor of the alarm system when the sensor detects the intruding motion occurred at the monitoring entrance/exit, and trigger at least a local warning device by the security control device to generate an alert signal. (4) Stop the alert signal when the intruding motion ceases or terminates. (5) Disable the security control device by switching the sensor to the control panel of the alarm system when the alarm system is armed, so that the sensor performs its alarm detecting function normally.

Claims

1. An auxiliary alert process of an existing alarm system, which is currently installed in a structure for general security purpose, having at least an entrance/exit sensor installed at an entrance/exit of said structure, comprising the following steps:

(a) maintaining said entrance/exit sensor installed at said entrance/exit of said existing alarm system in functioning condition when said existing alarm system is in a disarmed condition;

(b) monitoring said entrance/exit by said entrance/exit sensor to determine whether there is an intruding motion occurred at said entrance/exit;

(c) triggering at least a local warning device of said existing alarm system to generate an alert signal when said entrance/exit sensor detects said intruding motion occurred at said entrance/exit;

(d) stopping said alert signal when said intruding motion ceases or terminates; and

(e) switching said entrance/exit sensor to a control panel of said existing alarm system when said existing alarm system is in an armed condition, so as to render said entrance/exit sensor performing a normal alarm detecting function thereof, wherein a detecting signal is sent to a security control device connected between a control panel and said entrance/exit sensor of said existing alarm system when said entrance/exit sensor detects said intruding motion occurred at said entrance/exit so as to trigger said local warning device by said security control device to generate said alert signal, wherein said security control device automatically disables functions thereof once said existing alarm system is set to said armed condition, wherein said entrance/exit sensor works normally with said control panel when said existing alarm system is in said armed condition;

wherein said security control device comprises;

a central processor unit for computation, an input circuit for electrically connecting said entrance/exit sensor of said existing alarm system to said central processor unit,

a power supply electrically connected to said central processor unit for providing electrical power to said central processor unit,

a time count generator electrically connected to said central processor unit for generating counter signals for controlling a predetermined period of time for said alert signal,

an alarm output for connecting to said local warning device for generating said alert signal, an output circuit for electrically connecting said central processor unit with said control panel of said existing alarm system,

a PG selector which is a switch circuit for setting said central processor unit to select and program time period and function, and

a status controlling circuit for determining whether said existing alarm system is armed or disarmed,

wherein when said existing alarm system is armed, said PG selector bypasses said detecting signal sent from said entrance/exit sensor directly to said control panel of said existing alarm system to function normally, and when said existing alarm system is disarmed, said detecting signal sent from said entrance/exit sensor is input into said central processor unit of said security control device, wherein said central processor unit triggers said alarm output to generate said alert signal.

2. An auxiliary alert system, comprising a security control device connected between at least an entrance/exit sensor and a control panel of an existing alarm system which is currently installed in a structure for general security purpose, wherein said entrance/exit sensor of said existing alarm system is installed at an entrance/exit of said structure, wherein said security control device comprises:

a central processor unit for computation,

an input circuit for electrically connecting said entrance/exit sensor of said existing alarm system to said central processor unit,

a power supply electrically connected to said central processor unit for providing electrical power to said central processor unit,

a time count generator electrically connected to said central processor unit for generating counter signals for controlling a predetermined period of time for said alert signal,

an alarm output for connecting to a local warning device of said existing alarm system for generating alert signal,

an output circuit for electrically connecting said central processor unit with said control panel of said existing alarm system,

a PG selector which is a switch circuit for setting said central processor unit to select and program time period and function, and

a status controlling circuit for determining whether said existing alarm system is armed or disarmed;

wherein when said existing alarm system is armed, said PG selector bypasses a detecting signal sent from said entrance/exit sensor directly to said control panel of said existing alarm system to function normally, and that when said existing alarm system is disarmed, said detecting signal sent from said entrance/exit sensor is input into said central processor unit of said security control device, wherein said central processor unit triggers said alarm output to generate said alert signal.

3. An auxiliary alert system, as recited in claim 2, wherein said status controlling circuit is also connected to said control panel, wherein when said alarm system is armed or disarmed, said status controlling circuit detects and triggers said central processor unit to disfunction or function accordingly.

4. An auxiliary alert system, as recited in claim 2, wherein said PG selector is a switch circuit for said connection between said entrance/exit sensors and said control panel, wherein when said status controlling circuit detects that said existing alarm system is disarmed, said central processor unit activates said PG selector to switch off said connection between said entrance/exit sensors and said control panel of said existing alarm system, therefore said detecting signal from said entrance/exit sensor is processed by said central processor unit, therefore when said entrance/exit sensor detects a human motion, said central processor unit triggers said alarm output to activate and output visual and audio warning signals, besides when said status controlling circuit detects that said existing alarm system is in an armed condition, said central processor unit activates said PG selector to bypass said security control device and switch to directly connect said entrance/exit sensor to said control panel, so that said entrance/exit sensor and said control panel work normally.

5. An auxiliary alert system, as recited in claim 4, wherein said PG selector is a switch circuit for said connection between said entrance/exit sensors and said control panel, wherein when said status controlling circuit detects that said existing alarm system is disarmed, said central processor unit activates said PG selector to switch off said connection between said entrance/exit sensors and said control panel of said existing alarm system, therefore said detecting signal from said entrance/exit sensor is processed by said central processor unit, therefore when said entrance/exit sensor detects a human motion, said central processor unit triggers said alarm output to activate and output visual and audio warning signals, besides when said status controlling circuit detects that said existing alarm system is in an armed condition, said central processor unit activates said PG selector to bypass said security control device and switch to directly connect said entrance/exit sensor to said control panel, so that said entrance/exit sensor and said control panel work normally.
