COMMON MISTAKES AND HOW TO AVOID THEM

"De-Energize" vs. "Energize"
• "De-Energize" means the relay will be OFF under normal conditions and will switch ON when there is an alarm. This is
the default state and will correspond with the legend on the circuit board (N.O. and N.C.).
• "Energize" means the relay will be ON under normal conditions and will switch OFF when there is an alarm or if power
is lost, providing power-supervision. However, this will reverse your N.O. and N.C. contacts. In either case, you still
have both sets of contacts. The AUX relay cannot be configured in this way.
Zone # vs. Output #
These directly correspond. Zone 1 uses the Output 1 relay. Zone 2 uses the Output 2 relay. Using Zone 2, but wiring to your
alarm panel using the Output 1 relay will not work. To cover all zones with a single relay, use the AUX relay.
"no" in Programming
To program a zone, press the ZONE button. The active zone will be flashing. Select the zone number using INCREASE or
DECREASE, and then press ENTER. You will then see the word "no" flashing. This means "not operational"
and indicates the zone is currently off. When you see this flashing, press INCREASE or DECREASE to scroll
through your sensing options. Zones with no probe attached should be turned off. If you are trying to
turn a zone off, select "no" here.
Temperature Reading is Not Accurate
If the reading does not match your temperature reference, ask yourself the following questions:
• Is it programmed as the correct sensor type (Figure 2) and in the correct zone? If the displayed temperature is not even
close, this is most likely the problem.
• Has the temperature reference been calibrated, and is it known to be accurate?
• Is the reference probe in exactly the same place as the EA200/400 probe? It is normal for the temperature in a climate
controlled room to vary by several degrees.
If you need to match the EA200/400's reading to a reference, use the OFFSET feature to do this. Ensure you have a known-
good calibrated reference or you may be unintentionally changing an already accurate reading.
