ZP2-A Series Installation Manual
Connecting loop devices
Each loop can support up to 127 devices (using the address range 1 to 127). For
detailed loop device installation information, see your device installation sheet.
Connecting inputs
Input functionality
Each control panel has two supervised inputs, marked INPUT1 and INPUT2. For
input configuration, see “Field configuration” on page 99.
Connecting inputs
Connect input switches to INPUT1 and INPUT2, as shown in Figure 14 on page
32. For input supervision (open and short circuit), install a 15
kΩ
resistor.
If an input is not used, the 15
kΩ
end-of-line resistor must be installed across the
unused terminals to avoid an open circuit fault on the input.
