Abstract
Abstract The invention herein described relates to devices used to test the integrity of fire sprinkler systems. The present device incorporates a control panel which allows a single operator to electrically activate a test valve within a specific sprinkler network. The interval between the initiation of water flow and the resulting alarm signal is timed by the operator using the control panel. The operator can test any of the building's sprinkler networks simply by adjusting a rotary switch located on the control panel. In this manner, the time and expense associated with sprinkler testing may be greatly reduced by having a single operator perform dependable tests of the entire automatic sprinkler system from one location.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
93 words
An electrical system for testing the integrity of automatic fire sprinkler networks which each have at least one test value, comprising, a test control panel, means to couple said test control panel to an electric power supply, means to select a particular sprinkler network to be tested, electrical means to open and close the test valve on said particular sprinkler network, and means to time the interval between the opening of said test valve on said particular sprinkler network and the receiving of an electrical signal from said particular sprinkler network being tested.
Claim 2
Dependent Claim
93 words
An electrical system for testing the integrity of automatic fire sprinkler networks which each have at least one test value, comprising, a test control panel, means to couple said test control panel to an electric power supply, means to select a particular sprinkler network to be tested, electrical means to open and close the test valve on said particular sprinkler network, and means to time the interval between the opening of said test valve on said particular sprinkler network and the receiving of an electrical signal from said particular sprinkler network being tested.
Claim 3
Dependent Claim
39 words
The electrical system for testing the integrity of automatic fire sprinkler networks as recited in claim 1, whereby the means for selecting said particular sprinkler network to be tested is a rotary switch located on said test control panel.
Claim 4
Dependent Claim
46 words
The electrical system for testing the integrity of automatic fire sprinkler networks as recited in claim 1, whereby the electrical means to open and close the test valve on said particular sprinkler network to be tested is a test switch located on said test control panel.
Claim 5
Dependent Claim
73 words
The electrical system for testing the integrity of automatic fire sprinkler networks as recited in claim 3, wherein the means to time the interval between the opening of the test valve on said particular sprinkler network and the receiving of the electrical signal from said particular sprinkler network being tested is a digital timer located on said test control panel, and whereby said digital timer is activated and deactivated by said test switch.
Claim 6
Dependent Claim
33 words
The electrical system for testing the integrity of automatic fire sprinkler networks as recited in claim 4, whereby said digital timer is initialized by a reset button located on said test control panel.
Claim 7
Dependent Claim
47 words
The electrical system for testing the integrity of automatic fire sprinkler networks as recited in claim 5, whereby said test control panel houses a power switch, a power light, a fuse, a test light, a rotary switch, said test switch, said digital timer, and said reset button.
Claim 8
Dependent Claim
41 words
The electrical system for testing the integrity of automatic fire sprinkler networks as recited in claim 1, whereby said electrical system and said test control panel are independent of any other alarm device used in conjunction with said fire sprinkler networks.
