Protects Windows, Doors, Walls and Roofs Against Forced Entry

The SD-304 PG2 is a wireless PowerG innovative shock detector with optional magnetic contact and auxiliary input interfacing with PowerMaster-10 and PowerMaster-30 control panels (version 16 and higher).

The SD-304 PG2 fits windows, doors, walls or roofs and is ideal for residential or commercial installations. It detects and analyzes gross attacks or a series of low level shocks (up to 10 low level shocks within 30 seconds) and provides early warning of any attempt of intrusion before a burglar actually breaks-in.This potentially reduces the damage and losses to a property as a result of a break in and provides home and business owners with enhanced security. The SD-304 PG2 fits most windows and doors including those made from wood, metal and PVC.

The detector’s advanced digital processing uses a piezo shock sensor to precisely detect and analyze gross attacks or a series of low-level shocks while ignoring background vibrations, a major cause of false alarms. The SD-304 PG2 detector includes an optional Grade 3 magnetic contact and auxiliary input. As a three-in-one wireless detector, the SD-304 PG2 detector saves the cost and time of additional detectors while providing exceptional performance in varied applications.


SD-304 PG2 Features:

  • Uses revolutionary PowerG wireless technology to deliver outstanding reliability, robustness and efficiency
  • Can be installed quickly in locations where cabling would be difficult and unsightly
  • Early detection of gross attacks or low-level shocks
  • High immunity to background vibrations which can cause false alarms
  • Protects windows, doors, walls and roofs against forced entry
