General Information
This section provides general information about the hardwired zones in the system, plus
specific instructions for installing 2-wire smoke detectors, 4-wire smoke/combustion
detectors, and 2-wire latching-type glassbreak detectors.
Installing the Hardwired Zones
Common Characteristics for Zones 1-8
• EOLR-supervised zones supporting both open circuit and closed circuit devices.
• As many 4-wire smoke detectors as can be powered from Aux Power on the control (zones
2-7).
• Programmable for 10, 350, or 700mSec response.
• 350mSec (default) should be used for most standard contacts. For vibration-type contacts,
10mSec is more suitable.
Wiring Burglary and Panic Devices to Zones 1 - 8
1. Connect sensors/contacts to the hardwired zone terminals (8 through 20). See Figure 23.
VISTA-20BAY Summary of Connections diagram.
2. Connect closed circuit devices in series in the high (+) side loop. The EOL resistor must be
connected in series with the devices, following the last device. See Figure 23. VISTA-
20BAY Summary of Connections diagram.
3. Connect open circuit devices in parallel across the loop. The 2,000-ohm EOLR must be
connected across the loop wires at the last device.
If the EOLR is not at the end of the loop, the zone will not be properly supervised, and the system
may not respond to an open circuit on the zone.
High Resistance Supervision on Hardwired Zones 2-8
Special supervision in the control senses high resistance on hardwired zone loops 2-8,
causing a warning

and the affected zone number to be displayed when the system is
in the disarmed state. The system cannot be armed when this display is present. If the
system is in the armed state when the high-resistance condition occurs, no such warning will
be displayed until the system is disarmed.
