2.6 ALARM
The CPS-3M provides a normally open and normally
closed dry contact for alarming low or high temperature
conditions. Moreover, this same contact can be used to
signal a power failiure. It may be connected to an alarm
system or directly to a siren and / or auto-dialer.
Make the normally closed (NC) or normally open (NO)
connections as indicated in figure 2.
2.7 POWERING UP
Before powering up the CPS-3M, attach the faceplate to
the casing of the CPS-3M using the six screws previously
removed.
Set Selector knob to position (12).
Upon power up, the unit will test its display by briefly
lighting up all the segments of its LEDs. Make sure all
segments light up.
Following the LED display test, the unit displays the room
temperature.
If the temperature is not displayed, refer to the Trouble
Shooting section of this manual.
CHAPTER 2 - INSTALLATION
Momentary power interruptions may trigger false alarms!
To avoid them, when the CPS-3M is connected to an
alarm system, install a time delay relay between the
CPS-3M and the alarm system.
