The PG9935 is a wireless shock sensor that is used for monitoring doors and windows. This device picks up the intense shockwaves of a forced entry through a door or a window. Upon sensing these vibrations, the PG9935 will send a signal to the alarm system to alert it of the situation.
The main use of the PG9935 is for perimeter protection of a home or business. If an intruder tries to enter the building, they might not simply open the door or window. Instead, they might break down the structure and enter by force. This might cause a standard magnetic contact to not activate. However, the PG9935 will detect these heavy vibrations and alert the system. To reduce false alarms, the PG9935 senses and analyzes direct shocks, and it ignores any background vibrations.
Other features of the PG9935 includes an internal reed switch and an auxiliary input. The reed switch allows the PG9935 to be used as a standard door and window contact in conjunction with a magnet. When the magnet is separated from the sensor, it will cause the reed switch to activate. The sensor will then alert the system of the situation. The auxiliary input lets the PG9935 be used as a wireless transmitter for a hardwired device. The input can be configured for Normally
Open, Normally Closed and Single
The PG9935 is part of the PowerG lineup, and it offers the full functionality of a PowerG Sensor. The device can communicate successfully with a panel from up to 2 km away if a clear line of sight is obtained. It also uses 128-bit AES encryption to keep the device fully protected against any wireless hacking or takeover attempts.
NOTE: The maximum range for a PowerG Sensor when used with an IQ Panel 2 Plus System is only 2,000 feet in open air. This is considerably less than the advertised 2km range. The 2km range refers to when a PowerG Sensor is used with a DSC PowerSeries NEO System.
