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

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).
