Excellent Shock Sensor!
Submitted on 12/19/2019 Alarm Grid

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
