RELAY OUTPUTS
No. 4204
The VISTA- 10 can support 4 relay outputs via the use of a 4204
Output Relay Module
Output Relay Module. This module provides form C (normally open and normally
closed) dry contacts on relays that can be programmed to activate or deactivate to
perform some action in response to a predetermined event such as turning on
lights and/or closing a fire door in the event of a fire alarm condition. There are
many different uses for these relays, some of which are suggested in the table on
page 44.
The unit can be located inside the control’s cabinet or remotely (see MOUNT/NG
THE CONTROL, LOCK, & PC BOARD section and the instructions that accom-
pany the unit).
4204 Setup
The 4204 Relay Module has 4 Form C relays. Each relay can be used
independently for different functions. The following steps should be taken to
moDerlv set UDthe 4204:

Connect the 4204
to the control’s remote console terminals
(4-7), using standard 4-conductor twisted cable (for long wiring runs) or the
connector supplied with the 4204 (as shown in the Summary of Connections
diagram).
Set the 4204’s DIP switch for a device address of “1” (switch 2
“OFF” and switches 3, 4, 5 “ON”). Switch 1 determines the unit’s cover tam-
per response (“ON” = disabled, “OFF”= enabled).
/Vote: Some “early” units have only a 4-position DIP switch.
Set 1 to “OFF” and 2,3,4 to “ON”.
During programming (summarized here, but see the detailed procedure
in the PROGRAMMING THE SECURITY CONTROL section):
a. Program a “3” in field
●25.
b. Program fields *8O (Output Relays) and
●81 (Zone Lists) for the desired
relay responses.
Connect the desired field wiring to the unit’s relay contact terminals.
Output Relay Advisory
/f a re/ay is energized before a wired smoke detector is reset, the re/ay wi// be
stopped by the interruption of Aux, Power that resets the smoke detector. If this
is not desired, the power to the relay module should be supplied from another
12V power source (e.g., the same source that is powering external equipment
through the relay contacts).
