2.5 TEMPERATURE PROBE
Outside temperature probes use a “Class II” low voltage
circuit. These cables (AWG#18 min) can measure up to
500 feet (150 meters). Outside temperature probe is
illustrated in figure 2.
2.5.1 Outside temperature probe
Install the outside temperature probe in an area that best reflects the
overall outside temperature.
2.6 ALARM
The DIP-1/115 provides a normally closed and a normally
open dry contact for monitoring communication failures
between the DIP-1/115 and the ECS-M, loss of power
between the DIP-1/115 and the ECS-M and potentiometer
malfunction. This contact may be connected to an alarm
system, or directly to a siren and / or an auto-dialer.
Do the connection according to the normally open (NO) /
normally closed (NC) options illustrated in figure 2.
Use a shielded cable for probes. Connect the shields to
the “SHLD” terminal. Failure to do so may result in
inaccurate readings and inefficient protection against
lightening and electromagnetic fields.
Do not expose outside temperature probes to direct
sunlight !
Momentary power interruptions may trigger false alarms!
To avoid false alarms when the DIP-1 is connected to an
alarm system, install a time delay relay between the
DIP-1/115 and the alarm system.
