INTRODUCTION
The 8720 Device Program/Test Unit is a powerful programming and test tool that expedites installation of intelligent devices. The 8720 programs addresses into devices and tests them to assure they operate properly prior to installation. Prior to connecting a device circuit to the control panel, you can operate the loop from the 8720 (AC power must be used for this operation), allowing you to debug the circuit and test for ground faults. The 8722 package includes a label printer and a larger carrying case for the 8720 and printer. The 8712 is a carrying case for only the 8720.
DESCRIPTION
The 8720 Device Program/Test Device is a compact, portable, menu driven device that makes programming and testing of intelligent devices faster and easier than ever before. The 8720 electronically programs the device’s address into its non-volatile memory. The 8720 then tests the device’s functionality, assuring the installer that the device works properly prior to installation. The 8720 has an LCD display with keypad that prompts the installer through easy to use program and test menus that take little to no training for first time users. The unit is supplied with NiMH re-chargeable batteries and an AC power supply and will operate in either battery or AC modes. The batteries are easily exchanged with off-the-shelf Alkaline AA batteries.To program and test a detector, simply insert the detector in the 8720s integrated detector base and enter the device address as prompted on the 8720s backlit display. The address automatically increments to the next address for ease of addressing multiple devices, but the user can easily insert a different address if desired. The user also has the option of entering a loop number if they are printing labels at the same time. devices are in alarm. The operator can also use the 8720 to detect ground faults on the device loop. The 8722 package includes a printer and carrying case. Printer supplies are standard off-the-shelf models that can be purchased at any office supply or office superstore. Using the optional label printer, is a simple astelling the 8720 how many labels are required. The labels will automatically print as the devices are programmed. The label maker is operated on AC current. There is also an option to perform a loop test. (The 8720 will only operate with AC in this mode due to power consumption.) The 8720 will display the addresses and the device type, a summary count of devices (by type) communicating on that loop and indicate addresses that have no device and if thedevices are in alarm. The operator can also use the 8720 to detect ground faults on the device loop.
