Overview

What it is and who it is for

The DSC PG4985 is a PowerG two-way wireless flood detector for the 433 MHz band, part of the PGx985 family with the PG4985 (433 MHz), PG8985 (868 MHz) and PG9985 (912 to 919 MHz). A supervised 6 ft wire water probe sits at floor level and the transmitter sends an alarm when both probe contacts touch water. DSC lists the family for PowerSeries Neo, PowerSeries Pro and Qolsys panels.

The transmitter reports to 433 MHz PowerG receivers (HSM2HOST4, HS2LCDRF(P)4, HS2ICNRF(P)4, PG4920), sends a supervision signal every 4 minutes, and alerts the panel if the probe is disconnected. It runs on one 3 V CR123 lithium battery with an 8 year rated life and a 2.2 V low battery threshold. It measures 81 x 34 x 25 mm, weighs 53 g with battery, has a cover tamper and break-away back tamper, and operates from -10 to 55 C at up to 93 percent relative humidity, non-condensing.

  • Best for: detecting water at ground level, such as in basements.
  • System fit: PowerG 433 MHz receivers HSM2HOST4, HS2LCDRF(P)4, HS2ICNRF(P)4, PG4920; PowerSeries Neo, PowerSeries Pro and Qolsys panels.
  • Important to know: this is the 433 MHz version and works only with 433 MHz PowerG receivers; it is CE listed, and the UL/ULC listing applies only to the 912 to 919 MHz PG9985.
