Installing the Hardwired Zones
Common Characteristics of Zones 1–6
•EOLR-
supervised
zones support both open-circuit and closed-circuit devices.
• Support as
many
4-wire smoke detectors
as can be powered from Aux Power on the control
(zones 2–6).
•
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 1–6
To wire burglary and panic devices to zones 1-6, perform the following steps, referring to
Figure 22. VISTA-15/VISTA-15CN Summary of Connections
at the back of this manual.
1. Connect sensors/contacts to the hardwired zone terminals (8 through 17).
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.
3. Connect open-circuit devices in parallel across the loop. The 2000-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/Short Supervision on Hardwired Zones 2–6
Provides automatic high loop resistance detection (possibly caused by corroding contacts at
perimeter sensor points) on hardwired zones 2–6, and displays a CHECK message for the
affected zone when the system is in the disarmed state.
This panel also contains a Hardwire Short Detection circuit, and when enabled in
✱
30
,
detects a short in any wired zone and sends a sensor Trouble message to the Central Station
when the system is in the disarmed state. At the same time a CHECK message is displayed
on the keypad.
Either condition (high resistance or short) detected on any zone, prevents the system from
being armed until the offending condition is cleared. Conversely, when the system is armed,
and these conditions occur, an alarm is generated.
