Prosense PPS‐RCO Quick Installation Guide
System Status
Prosense PPS‐RCO Series detectors has four LEDs on main board. Power LED (green) shows
system power status and yellow LED shows fault status. Fault relay will be activated and
Fault LED (yellow) will start flashing right after power applied. After appoximitly 90 sec the
yellow LED will be turned of and only power LED (green) will start blinking. This status means
that detector is ready to normal operation. In case of fault power LED (green) will contiune
blinking and fault LED (yellow) will be lit solid. The alarm LEDS (red) will be activated when
detector measures gas level at alarm thresholds and also activate related alarm LEDs.
First time switch on (Commissioning)
WARNING
The following procedure requires the detector cover to be removed while carrying out
supply voltage checks. Therefore the appropriate permits to work should be sought in
preparation. Prior to carrying out any HOT WORK ensure local and site procedures are
followed. Ensure that the associated control panel output actuation is inhibited so as to
prevent false alarms.
Caution: The following procedure should be followed carefully and only performed by
suitably trained personnel
1. Remove the detector cover
2. Make sure the detector's output and power input connections done correctly
3. Check that all electrical connections are terminated correctly
4. Switch On the external power supply to feed the detector. If it is connected to DP32
Panel, cables should be installed according to DP32 Panel user manual as panel can
provide both power and communication connections to the detectors.
5. Using a Digital Multi Meter (DMM), check the Supply Voltage at the terminals V+ and V‐
this should be a minimum supply voltage of 12VDC (Maximum supply voltage is 24VDC).
6. Check LED status on detector main board. LED status should be like explained above
after applying power.
7. Wait two minutes and confirm detector LED status pointing normal operation. If
detectors used with DP32 Panel, panel should recognise each detector correctly at their
addresses.
8. Switch Off the external power to the detector.
9. Fit the cover and make sure non of the cables cause an obstruction while fitting cover
10. Switch on external power to the detector or panel if used.
