Good Panic Button
Submitted on 09/24/2020 Alarm Grid

The DSC WS4938 is a single-button panic switch for security systems that accept the 433 MHz wireless frequency. Compatible systems include the DSC Impassa, a DSC PowerSeries with added receiver, and the 433 MHz Qolsys IQ Panel 2 Plus. The device is very easy to use, as you simply press and hold the single button on the fob for at least two (2) seconds. Many users will keep the device on-hand at all times in case an emergency situation occurs. Overall, we think this is a simple, yet effective single-button panic switch. We give the DSC WS4938 a 5-Star rating.

There are many things to like about the DSC WS4938. For one, the button is large and easy to press. The fact that you need to hold the button for two (2) full seconds is a nice touch, as that helps prevent false alarms. We like the fact that the device comes with a neck strap and a multi-function clip. These accessories make it less likely that a user will lose the DSC WS4938. Another positive aspect is the fact that the device is water resistant, so a user can carry it in the shower or bath. However, it should not be fully submerged in liquid. Finally, we like how the device can be programmed to trigger an intrusion, fire, or auxiliary medical panic, depending on the needs of the user.

There are not many downsides for the DSC WS4938. One limitation is that the device is only for 433 MHz security systems, which does restrict how the device can be used. We also don't like how the panic switch is very bare, with nothing more than a base black design. We're not expecting a grand and glorious design, but this is indeed one of the plainest sensors we have ever seen, and some users may forget its function as a result. There is also the consideration that you will need to replace the CR2025 coin battery every few years to keep the device running. But really, these downsides are nothing major, and they do not stop us from awarding the DSC WS4938 with a 5-Star score.

Good: Large Button, Easy to Press, Requires 2-Second Input, Prevents False Alarms, Included Accessories, Water Resistant, Program as Needed

Bad: 433 MHz Systems Only, Very Bare & Plain Device, Will Require Battery Replacements

Bottom Line: 5 Stars
