Polling Loop Supervision

A short on the polling loop is indicated by a trouble on

zone 997 and reports as a trouble condition only. If

annunciation is desired, program the zone as type 05.

If a device on the polling loop fails (the panel cannot

"see" that device), the system displays a trouble

condition for all zones on that device. If the panel is

armed when a device fails, and the zone is a burglary

zone, the will go into alarm

A trouble on zone 997 prevents a partition from

being armed, unless all polling loop zones on

that partition are bypassed.

Using the 4297 Polling Loop Extender

The 4297 Polling Loop Extender may be used to provide

additional polling loop current, to extend the polling

loop wire run length, and/or to provide individual

electrically isolated polling loops. Refer to

Figures 3-17

and 3-18

, to follow.

DO NOT use the 4197 Polling Loop Extender

module with the VISTA-128BP/VISTA-250BP

Be sure to include the total current drawn on

the polling loop when figuring the total auxiliary

load on the panel’s power supply.

Wireless Zone Expansion

The 5881ENHC RF Receiver and the 5869 Holdup

Switch Transmitter are listed for UL Commercial

Burglary applications. All other RF receivers and

transmitters are not listed for UL Commercial

Burglary applications.

The following table lists the receivers that may be used

and the number of zones they support.

5800 Series Receivers

Receiver Zones

5881L up to 8

5881M up to 16

5881H up to 250

In Canada, 5800 systems must use 5882 Series

receivers: 5882L/5882H. Information to the 5881

Receivers applies as well to the 5882 Receivers.

Both receivers use the same transmitters.

RF System Operation and Supervision

The 5800 RF system operation has the following

characteristics:

•

The receiver responds to a frequency of 345MHz.

•

The receiver has a nominal range of 200 feet.

•

Supervised transmitters send a supervisory signal

every 70-90 minutes.

•

Zones 988 and 990 are used to supervise the RF

reception of receivers 2 and 1, respectively. The

reception is supervised for two conditions:

1. The receiver goes “deaf” (doesn’t hear from

any

transmitter) within a programmed interval of

time (defined by program field 1*30).

2. Proper RF reception is impeded (i.e., jamming

or other RF interference). The control checks

for this condition every 45 seconds.
