STANDARD RELAY 1, 2, AND 3
Every ST-72 comes standard with three programmable relays that the user can
individually program to suit their needs. This is achieved through the
STANDARD
RELAY
menus accessed from the
ALARM OUTPUTS
menu. Only one Standard
Relay menu screen is shown in Figure 2-9 because all the standard relay’s menus are
identical. Under the
STANDARD RELAY
menu the user can configure the following.
Alarm Outputs
Standard Relay 2
Standard Relay 3
Horn/Piezo
Discrete Relay
Programmable Relay
Standard Relay 1

2.3.1.1 A1 A2 & A3 VOTES REQUIRED
A1 Votes Required, A2 Votes Required, & A3 Votes Required
are the number
of A1, A2, & A3 level alarms that must be present for the relay to activate. This allows
creation of logical AND function equations that control standard relays. Default settings
for standard relay 1 are
A1 Votes = 01 A2 Votes = 00
&
A3 Votes = 00
which
causes relay 1 to trip if any channel has an A1 level alarm active. Default settings for
standard relay 2 are
A1 Votes = 00 A2 Votes = 01
&
A3 Votes = 00
which causes
relay 2 to trip if any channel has an A2 level alarm active. Example: If either default
setting is modified such that
A1 Votes = 02
and
A2 Votes = 01,
then any two
channels must have an A1 level alarm active and any one channel must have an A2 level
alarm active to trip that relay.
REMEMBER!
One of the A1s and the A2 could be on the
same channel. These level alarms must come from a channel included in the
Zone
entry described below.
2.3.1.2 ACKNOWLEDGE

YES
allows the standard relay to be deactivated during alarm
conditions by an
Alarm Reset
. This is useful if an audible device is being driven by the
relay
