VISTA-40 Installation and Setup Guide

Using 2-Wire Latching Glassbreaks on Zone 8

Zone 8 can support 2-wire glassbreak detectors. The zone provides enough standby current to power up to 50 2-wire glassbreak detectors meeting the requirements listed below.

Compatible Glassbreak Detectors

Use detectors that meet the following ratings:

5VDC–13.8VDC

Greater than 20k ohms (equivalent resistance of all detectors in parallel)

Less than 1.1k ohms (see note below)

2mA–10mA

Less than 6 seconds

Figure 3-15: Wiring Latching Glassbreaks to Zone 8

•The alarm current provided by zone 8 supports only one glassbreak detector in the alarmed state.

•Do not use other N.O. or N.C. contacts when using glassbreak detectors on zone 8. Other contacts may prevent proper glassbreak detector operation.

NOTES:

•You can use detectors that exceed 1.1k ohms in alarm, provided they maintain a voltage drop of less than 3.8 volts in alarm.

•The ASC-SS1 detector has been tested and found to be compatible with these ratings.

To wire 2-wire latching glassbreak detectors to zone 8, perform the following steps:

Step Action

1Select compatible 2-wire glassbreak detectors that meet the requirements stated previously.

2Connect detectors across zone 8 (terminals 21 and 22). See Figure 3-15.

3Connect the EOL resistor at the last detector in the loop across the zone’s terminals. You must connect the EOL resistor across the loop wires at the last detector.

Installing RPM Devices

The polling loop provides both power and data to the RPM devices, and is constantly monitoring the status of all zones enabled on the loop. The maximum current

Compatible Polling Loop Devices

draw of all devices on the polling loop cannot total more than 64mA (unless the system uses a 4297 Polling Loop Extender Module).

Devices that can be programmed via either DIP switches or the built-in unique serial number must be set for the serial number mode operation.

All devices on the polling loop must be wired in parallel to the [+] and [-] polling loop terminals of the control panel (24 and 25). You can wire from device to device, or have multiple branches connected directly to the control panel in a star configuration.
