RELAY 1 / RELAY 2 MENUS
The
Relay 1
&
Relay
2
menus are identical except
Relay
2
has an
acknowledge
feature
useful if it controls an audible device. All other
Relay 1
&
Relay
2
features are
identical and therefore are discussed only once.
Figure 2.9
The
Set Relay Logic
menu shown below in Figure 2.9 offers additional “voting”
flexibility by controlling the channel alarm combinations that will trip this common
alarm relay.
“OVR”
on the menu’s right side stands for
override
and means ANY of
the selected alarms will activate the relay. The
“OR”
/
“AND”
columns work
together based upon the following logic equation:
[AND column selections]
ANDED WITH
[OR column selections] = relay
activation.
For example, if Ch1A1 & Ch2A1 are selected in the AND column and Ch1A2 &
Ch2A2 are selected in the OR column, the logic equation is [Ch1A1
AND
Ch2A1]
ANDED WITH
[Ch1A2
OR
Ch2A2]. This requires both A1’s along with either A2
to activate the relay.
