Abstract
A portable, preferably hand-held device is provided which may be used to test device loops in fire safety systems for short circuits, open circuits, ground faults and can test the response of the devices in the loop before or after the device loop is connected to the system.
Claims26
A system comprising:
- a device loop controller;
- one or more device loops configured to communicate with device loop controller,
- wherein each of said one or more device loops includes a plurality of devices, and
- wherein each of said one or more device loops defines an operatively connected state in which said one or more device loops communicate with said device loop controller, and an operatively disconnected state in which said plurality devices in said one or more device loops communicate with each other;
- a hand-held device having a display, said hand-held device configured to:
- operatively connect to said one or more device loops when said one or more device loops are in said operatively disconnected state;
- and
- test said one or more device loops when said one or more device loops are in said operatively disconnected state, wherein said one or more device loops are operatively connected to said device loop controller after being tested by said hand-held device, wherein said hand-held device is operatively connected to said one or more device loops to determine whether devices in said one or more device loops are communicating properly.
5 more elements
A method of using a hand-held device for testing a device loop in a system, the method comprising:
- providing a device loop controller;
- providing one or more device loops configured for communication with said device loop controller, wherein each of said one or more device loops comprised of a plurality of devices, wherein each of said one or more device loops defines an operatively connected state in which said one or more device loops communicate with said device loop controller, and an operatively disconnected state in which said plurality devices in said one or more device loops communicate with each other;
- providing a hand-held device having a display;
- testing, said one or more device loops in said operatively disconnected state utilizing said hand-held device;
- and
- operatively connecting said one or more device loops to said device loop controller after said one or more device loops have been tested.
3 more elements
A hand-held device for testing, programming, or a combination thereof, devices and device loops in a system comprising:
- a housing;
- a display for displaying device and device loop information;
- a keypad connected to the housing;
- a first connecting device comprised of one or more connectors for connecting the hand-held device to a device loop for testing the device loop,
- wherein said device loop defines an operatively connected state in which said device loop communicates with a device loop controller, and an operatively disconnected state in which said devices in said device loop communicates with each other;
- and
- a second connecting device for connecting at least one of said devices directly to the hand-held device for testing or programming or a combination thereof.
