2 HARDWARE CONNECTIONS HEADING The loop tester hardware requires a free serial port on the PC, either internal or via a USB extension, a mains power supply and a direct connection to the device loop. It need only be connected to one end of the loop, effectively making it a spur. • Connect the loop leads into the loop tester hardware ensuring to match the positive and negative sides of the connection. • Connect the device to the PC serial port using a regular RS232 cable.
PUBLIC 4 LOOP ACCESS DEVICESLEVEL 1 Before devices on the loop can be interfaced with, they need to be addressed and learned by the loop tester. If the loop being tested is already commissioned, using the existing device addresses is advisable under normal circumstances. Once the loop devices have been learnt by either of the processes below, the features for querying the loop devices will be enabled and the view will automatically switch to the “Devices” pane. 4.
4 LOOP DEVICES HEADING 4.2 Soft addressing Soft addressing will assign a new, and potentially different, address to every device found on the loop. This does mean that once testing is complete, the loop will have to be commissioned again by the panel it is to be connected to. Do not use this option unless you have to. A password will be required from the user to initiate the soft addressing process to avoid unauthorised and/or accidental readdressing of commissioned loop devices. See “Installation.” 4.
SILENCE 5 DEVICEALARMS STATUSES 5.1 Device icons The “Devices” pane will show all known devices on the loop. If a device is missing it most likely indicates a problem with the physical connections in the loop. This will need to be resolved before any interaction with the missing devices will be possible. A “Missing device” icon will be displayed if the loop was searched over a specific range. The device icons each show a symbolic representation of the device type along with its given address.
5 DEVICE STATUSES HEADING 5.1.3 Test LED The test LED of any device can be enabled or disabled from this pane. Right click on the device icon and select “Toggle test LED”. Also, on small loops, options for turning the test LED on for all devices is available from the “Settings and Commands” pane. Note: enabling the test LED of a sounder will cause the sounder to enter the alarm state. 5.1.
5 DEVICE STATUSES 5.2.1 Device classes 5.2.1.1 Analogue Devices that fall into this category have their value interpreted according to ranges for OK, Prealarm and Alarm. The boundaries for these ranges can be changed. Any value that is outside these ranges will be interpreted as a fault. 5.2.1.2 Enumerating The analogue values of these devices are assigned specifically. A list of values for OK, Prealarm and Alarm can be assigned. These lists should be space separated (e.g. “10 20 30”).
6 REPORTS Two flavours of log are available depending on what details you need. 6.1 History log This log shows all the history of events that have taken place on the loop since the application was started (or the log was manually cleared.) It is possible to only select certain event types to reduce report size and improve readability. This report is available from the “Communication history” pane. 6.1.
7 LOOP DATA BASES 7.1 What is a loop database? A loop database is the computer record of what devices are connected to the loop. This database can be used to compare what has been found by the loop tester to what is believed should be there according to the system installation. 7.2 Loop database sources A loop database can be acquired from one of two places as follows. 7.2.
7 LOOP DATA BASES 7.4 Using loop data Once loop data has be loaded and a loop selected the data can be used for a variety of things. Retrieving a list of devices from the loop tester hardware using either pre-addressed search or by soft addressing does not alter the loop data nor does it change the loop selection. 7.4.1 Compare the detected loop Perform an address by address comparison of the loop detected by Loop Tester to that of the selected loop.
7 LOOP DATA BASES 7.5 Saving loop data It is also possible to create a loop database (suitable for loading into Site Installer) directly from Loop Tester. Once a list of devices has been retrieved and verified to be correct, you can select “Save to Site Installer” from the “Use loop database” menu. Shown to the right are the options that must be filled in prior to saving the data. The Site Installer Database path must be an already existing database created using Site Installer.
