2.5.1 Single Temperature Probe
Install a single temperature probe in an area that best
reflects the overall temperature of the room. Connect the
two leads and the shield of the temperature probe to the
control panel terminals labelled “Probe” as indicated in
Figure 3.
2.5.2 Averaging (optional)
Four temperature probes are required if temperature
averaging is desired in larger rooms. Place the probes in
appropriate locations to best average the ambient
temperature. Refer to Figure 4.
2.5.3 Humidity Probe (optional)
Install one humidity probe in an area that best reflects the
overall humidity of the room. Connect the humidity probe
to the control panel terminals labeled “Probe” as indicated
in Figure 3.
2.6 ALARM
The ECS 1M provides a normally open and normally
closed dry contact for alarming low or high temperature
conditions. In addition, this same contact can be used to
signal a power failure. This contact may be connected to
an alarm system, or directly to a siren and/or auto-dialer.
Make normally open or normally closed connections as
indicated in Figure 3.
Use shielded cabling for probes . Connect the shields
to “SHLD” terminal. Failure to do so may result in
inaccurate readings!
Momentary power interruptions may trigger false
alarms! To avoid false alarming when the ECS 1M is
connected to an alarm system, install a time delay
relay between the ECS 1M and the alarm system.
