PPSR standalone relay detector versus PPS multi-detector network
| Selection point | Model-family evidence |
|---|---|
| Use case | PPSR car-park and tunnel detector variants for CO, NO₂ and LPG. Each PPSR detector has onboard switching relays for directly signalling alarms or activating correctly rated intermediate controls. |
| Sensor technology | Electrochemical sensor for CO or NO₂, catalytic sensor for LPG; target-gas range, life and cross-sensitivity depend on the selected head. |
| Local output distinction | PPSR’s onboard relays distinguish it from a PPS detector designed for RS485 addressable control via PPS Manager. Choose per-zone architecture before selection. |
| Mechanical environment | Manufacturer lists ABS plastic housing, IP54 and 3 PG11 cable entries on the PPSR family page. Confirm moisture/cleaning exposure within IP54 limitations. |
| Alarm design | A relay-powered ventilation fan must use external appropriately rated controls when fan motor current exceeds detector-contact ratings. Record setpoints and detector gas calibration. |
Do not transfer PPS+ EN 50545-1 certificate claims or hazardous-area Ex approvals automatically to PPSR. Verify the exact PPS-RCO, PPS-RNO2 or PPS-RLPG model and manufacturer wiring manual before safety-critical use.
