DSC PG9911B - PowerG 915MHz Outdoor Siren Blue LED W/Batt Reviews
Submitted on 05/27/2020 Alarm Grid
The DSC PG9911B is a wireless outdoor siren and strobe light that communicates at 915 MHz. It can be used with any system that supports the 915 MHz PowerG protocol. This includes all versions of the Qolsys IQ Panel 2 Plus, any DSC PowerSeries NEO Panel with an added wireless transceiver, and the DSC Iotega. It produces sounds of up to 110 dB, thereby making it one of the loudest wireless sirens available. In most cases, 110 dB will be a bit overkill for a residential location, and a quieter siren would be more practical. But for users who really need a loud siren, the DSC PG9911B certainly gets the job done. For its ease of use and overall effectiveness, we give the DSC PG9911B a 5 Star rating.
There are many things we like about the DSC PG9911B. For one, it is super loud. The 110 dB sound rating is nothing to scoff at. This is borderline loud enough for industrial and commercial locations. And for a residential location, it will be extremely loud. We also like the fact that this siren includes a built-in strobe light to provide a visual indication of an alarm. As a PowerG device, the DSC PG9911B offers a great wireless range, and it is protected by 128-bit AES encryption. This is military grade encryption, and the device is virtually impossible for others to hack or take over wirelessly.
There are not many downsides regarding the DSC PG9911B. One issue is that it can only be used with systems that support PowerG. If your system does not support PowerG, then this siren is not for you. Also, there is no way to adjust the siren volume. If you find that 110 dB is too loud, then there isn't much you can do to quiet the siren. But these downsides are extremely minor, and they do not stop us from giving the DSC PG9911B a 5 Star rating.
Good: Extremely Loud, Strobe Light, Great Range, Encryption
Bad: PowerG Systems Only, Cannot Adjust Volume
Bottom Line: 5 Stars
