Reference & Installation Manual
Figure 6: Single Zone Input Connections
2.14 Double Zone Connections
Enabling the ATZ feature (see
) allows you to install two
detection devices per input terminal. Connect the devices as shown in
. For UL listed Burglary System installations only, use EOL resistor
part #2011002000.

2.15 Combus Connections
The 4-wire combus can support 127 (EVO48) or 254 (EVO192) modules.
Use star and/or daisy chain configuration. The total length of wire cannot
exceed 914m (3000ft).
Before connecting a module to the combus, remove AC and battery power from the
control panel.
2.15.1 Connecting the Combus in Noisy Environments
When installing the combus wires in proximity to high electrical
interferences or across separate buildings, use shielded cables:
Within the Same Building:
Strip the outer jacket at one end of the
shielded cable to expose the shield and connect the shield to the control
panel ground (not the dialer ground), while leaving the shield at the other
end of the cable open (floating).
