Introducing GB-502 PG2
Overview
The GB-502 PG2 is a wireless PowerG Two-way acoustic glass-break detector designed to detect the breaking of framed glass mounted in an outside
wall. This detector is wall/ceiling mountable and suitable for most types of window/door glass: plate, tempered, laminated, wired, coated and sealed
insulating glass. No adjustment is necessary during installation – the detector is fully pre-calibrated.

Figure 1. General View
The acoustic sensor of the GB-502 PG2 is omni-directional, providing full coverage. Coverage is measured from the sensor to the point on the glass
farthest from the sensor. The sensor can be mounted as close as 1.5 m (5 ft) from the glass.
Figure 2. Typical Range Measurement
When mounted on opposite walls, on adjoining walls or on the ceiling, the range is 7.6 m (25 ft) for plate, tempered, laminated, wired, coated, and
sealed insulating glass. The coverage range also depends on the angle between the detector and the glass – for a higher angle, the maximum range is
reduced, see the following table for details.
Angle (degrees) 0 30 45 60 75 90
Maximum range m (ft) 7.6 (25) 7 (23) 5.5 (18) 4 (13) 2.5 (8) 0
