ZP3 Fire Control Panel Installation, Commissioning, and Maintenance Manual 143
The panel number is entered from right to left. Illegal panel values may occur as
the panel number is being entered, which is why an invalid condition is displayed
as blank (to prevent confusion).
When the panel number is entered, the menu text changes from “Enter-Save” to
“Home-Save” thereby making the Enter button functionality redundant. Pressing
the F1 button toggles the panel status of the selected panel.
If the Esc button is pressed, all changes made in this menu will be lost. Pressing
the Home button saves all changes.
The panel reads six analogue values from each device, each time it polls that
device. Each value is a whole number that can range from 0 to 255. These
values can be interpreted in order to provide a comprehensive analysis of each
device and the system as a whole.
The six readings are listed below in the order in which they are read and
conventionally displayed:
• Reading 1 Reference group
• Reading 2 Polling group
• Reading 3 Device type
• Reading 4 Reference (low)
• Reading 5 Device status (analogue reading)
• Reading 6 Device specific
The following sections give the meanings of each analogue reading. Reading 6 is
only relevant for certain specialized devices, and is usually zero.
The reference group reading identifies the device reference group type. This
value is used for the following:
• Decide if a device is online (connected) or offline (disconnected).
• Determine the health of a device and how well the device or the line driver
board is calibrated.
• Identify the device as an intrinsically safe (EX), ZR, ZP or ZX device.
The values are interpreted as follows (as for Table 37 on page 109):
• 0–39: A value in this range indicates to the panel that there is no device at the
polled address. It is offline.
