DSC PG9935
PowerG 915MHz Wireless Shock Detector
Description
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 type of entry might cause a standard door or window contact not to 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 include 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, which comes included. 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 or Single End-of-Line resistor use.
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 2,000 feet in open-air environments. 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.

The DSC PG9935 is a PowerG Shock Sensor designed for use with security systems that support wireless PowerG Sensors. The sensor responds to intense shock waves caused by someone smashing a window or breaking down a door. It is a good sensor for monitoring forced entry. The sensor also includes an internal reed switch and an auxiliary input to add to its versatility. This is a great sensor, and we have no problem giving it a perfect 5 Star rating.
There are many things we like about the DSC PG9935. For one, it has the excellent range of a PowerG Sensor. It can communicate with a panel from up to 2 km away depending on the system it is used with. The sensor also utilizes 128-bit AES encryption for enhanced wireless security and protection. The device offers a load of different features. In addition to being used as a shock sensor, it also offers two (2) other main functions. It has an auxiliary input so that you can connect a hardwired contact sensor and have it communicate with the system wirelessly. The auxiliary input allows for Normally Open, Normally Closed, and Single End-of-Line contacts. The PG9935 also has a built-in reed switch. If you add a magnet, then it can operate as a conventional door/window contact in its own right.
There aren't really many downsides to the DSC PG9935. The biggest concern is that as a shock sensor, it is somewhat prone to false alarms. Although the sensor is designed to only respond to intense vibrations, it's possible that any significant shock wave could set it off. This could include something falling or even a relatively minor earthquake. We find that listening glass break sensors are usually less prone to false alarms than shock sensors. But if you understand that risk, then the PG9935 is a great overall device. We rate it at 5 Stars.
Good: PowerG Range, 128-Bit AES Encryption, Auxiliary Inpuit, Built-In Reed Switch
Bad: Possability of False Alarms
Bottom Line: 5 Stars
