Earth Ground Connections

Metal Cold Water Pipe:

Use a non-corrosive metal strap (copper is recommend-

ed) firmly secured to the pipe to which the ground lead

is electrically connected and secured.

AC Power Outlet Ground:

Available from 3-prong, 120VAC, power outlets only. To

test the integrity of the ground terminal, use a three-

wire circuit tester with neon lamp indicators, such as

the UL-Listed Ideal Model 61–035, or equivalent,

available at most electrical supply stores.

Installing the Hardwired Zones

Common Characteristics for Zones 1–6

•

Response time from 300 - 500 milliseconds (400

milliseconds nominal)

•

Zone 3 can be programmed (in field

✱

52) for

normally-closed sensor fast response (10mSec max)

to an open (suitable for vibration type contacts).

Default response is 400mSec nominal, which should

be used for most standard contacts

•

EOLR supervised zones support both open-circuit

and closed-circuit devices.

•

As many 4-wire smoke detectors as can be powered

from Aux Power on the control (on zone 5).

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 the VISTA-

10SE Summary of Connections

diagram located

on the

inside back cover of this manual.

1. Connect sensors/contacts to the hardwired zone

terminals (8 through 16). See the Summary of

Connections diagram.

2. Connect closed circuit devices in series in the high

(+) side of the loop. The EOL resistor must be

connected in series with the devices, following the

last device. See the Summary of Connections

diagram.

Connect open circuit devices in parallel across the loop.

The 1000 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.

Smoke Detectors

Wiring 4-Wire Smoke Detectors on Zone 5

The system will support as many 4-wire detectors as

can be powered from Auxiliary Power on the control on

zone 5. Refer to the detector’s instructions for complete

details regarding its proper installation and operation.

1. Connect 12-volt power for the detectors from

Auxiliary Power terminals

and

(which will

interrupt power for fire alarm reset). Observe proper

polarity when connecting detectors. See Figure 2-8.

2. Connect detectors (including heat detectors, if used)

across terminals of zone 5. All detectors must be

wired in parallel.

Remove 1000 ohm EOL resistor if connected

across the zone terminals. You must connect

the EOL resistor across the loop wires at the

last detector.

3. To meet NFPA 72 requirements, you must use a

supervisory module to supervise power (e.g., System

Sensor No. A77-716B Relay module).

4-Wire Smoke/Combustion detectors are

not

permitted in UL installations.
