Connection to BMS/BAS
The GPS-iMOD has an internal ionization output sensing circuit. The external GPS-iDETECT-P™ is not required but may
be installed as an option. Integral alarm “dry” contacts will close when the system is on and operating properly. To tie
into the BMS/BAS for remote monitoring, use 18/2 twisted pair, SHIELDED, plenum rated cable and connect to the BMS/
BAS ALARM contact terminals. Connect the cable shield to the ground terminal as shown in FIGURE 20. The terminal
block may be removed for ease of wiring.
Keep the control wiring as far from the HV wiring as possible. DO NOT
RUN BOTH CABLES TOGETHER AND DO NOT ZIP TIE CONTROL WIRING TO FLEXIBLE HV CABLES!
CONNECTION OF GPS-iDETECT-P
1. Remove the red jumper wire between C and NO on the GPS-iDetect-P terminal block (see FIGURE 15 for
jumper wire).
2. Using 300V, 18/4, plenum rated, SHIELDED cable wire between the GPS-iDetect-P power and normally open
terminals and the GPS-iMOD power supply GPS-iDetect-P terminal block as shown in FIGURE 20. Ground the
18/4 SHIELD to the ground terminal on the GPS-iDetect-P terminal strip shown in FIGURE 20.
Only ground ONE end of the shielded cable.
Do not ground the end connected to the GPS-iDETECT-P sensor.
DO NOT RUN CONTROL WIRING WITH HV CABLES!
3. Mount the GPS-iDetect-P using the included 1” coated pipe clamp and secure to a GPS-iMOD section as
shown in FIGURE 21 using a nut and bolt.
4. When the GPS-iDetect-P senses output, the “Plasma On” light will illuminate on the front panel of the power
supply and the BAS/BMS Alarm Contacts will close. When using the GPS-iDetect-P in conjunction with the
GPS-iMOD power supply, always connect to the BMS/BAS using the BMS/BAS Alarm Contacts, not the
contacts on the GPS-iDetect-P.
