Bosch ISC-PDL1-W18G TriTech Dual-Tech Motion Detector

Bosch TriTech dual-technology motion detector — PIR + microwave with First Step Processing, anti-mask, and 18m range. The false-alarm-resistant detector for HVAC-noise environments and large commercial spaces.

Deployment context

Warehouses with overhead HVAC and ceiling-mounted heat-sources, retail with high-bay lighting, commercial offices with after-hours building automation. Any space where single-tech PIRs produce nuisance alarms from thermal-noise sources.

Zones, inputs & wiring architecture

Connects to one panel zone input. EOL supervision via the panel. Tamper switch reports to a separate zone or via the wiring tamper line.

Communicator & monitoring compatibility

Not applicable (detection device).

False alarm & reliability positioning

Dual-technology requirement — both PIR and microwave must trigger simultaneously to report alarm. First Step Processing distinguishes intrusion patterns from thermal/lighting transients. Anti-mask defeats attempts to obscure the detector lens. Pet-immune variants available for 50lb threshold.

UL / commercial compliance

UL639 (intrusion detection), ULC-S306. ULC-Listed for commercial burglary deployment.

Commonly paired hardware

DSC PowerSeries Neo HS2128 or Bosch B9512G panel · DSC HSM2108 zone expander (one zone per detector) · 12VDC alarm-rated cable from the panel · ceiling or wall mounting hardware
