DSC PG9911B

The DSC PG9911B PowerG Outdoor Siren is a great way to provide a reliable and powerful sounder to a separate area of your home or business. It produces sounds of up to 85 dB, and it is prepared to stand up to a tough outdoor environment. It also features a strobe light for visual alerts.

Some users may find that the siren used with their alarm system isn't loud enough. Others may want a separate, additional siren to use on a different part of the property. That is where the DSC PG9911B comes in. This device is a separate, external siren that can produce sounds of up to 85 dB. This is as loud as a typical hard rock concert. At this impressive volume, the siren is plenty loud enough to alert building occupants and other people nearby to an alarm event. This is perfect for any burglary or fire that may occur in the home or business.

In the past, users had to rely on a hardwired siren if they wanted to make their alarm system louder. Wiring and getting power to a hardwired siren can be a somewhat challenging process for a DIY user. But a wireless siren like the PG9911B eliminates that need. Instead, it is simply enrolled wirelessly and programmed with a compatible alarm system. Since the PG9911 is fully weatherproof, with an IP55 rating, it will have no problem functioning in an outdoor environment.

One very useful aspect of the DSC PG9911B is that it will differentiate between fire and carbon monoxide (CO) alarms. The outdoor siren will produce a Temporal 3 (T3) sound for a fire alarm, and a Temporal 4 (T4) sound for a CO alarm. This can be very important for meeting specific fire codes and building requirements. Many users will install these devices around the premises so that those on-site or nearby are properly alerted to a fire or CO event.

The PG99111B is part of the PowerG Series, and it offers the full functionality of a PowerG Sensor. It will function from up to 2 km away from a DSC Power Series Neo system when installed with a clear line of sight. With the Qolsys IQ Panel 2 Plus panels, the range is still an impressive 2,000 feet and on the IQ Panel 4, the range is closer to 4,000 feet. This makes it perfect for use on a separate area of the property to ensure that everyone can hear the alarm. The device also utilizes 128-bit AES encryption to protect against wireless hacking attempts.

For users who may want to use a strobe but not a siren, the siren connector can be unplugged from inside the PG9911B. This will allow the Strobe to continue working, while the Siren is silent. This won't cause any damage to the unit, and the siren can be put back into use at any time. Just be sure the unit is powered completely down when plugging or unplugging the siren. When the PG9911B is used with a DSC Power Series NEO panel, it can be programmed to activate, or not, on various alarm types (Fire, CO, Burg, Flood, etc.). By default, it is enabled for all of these alarm types. The strobe can be enabled or disabled via panel programming as well. On the Qolsys IQ Panel 2 Plus and IQ Panel 4, the programming options are more limited.

Each PG9911B comes with two (2) backup batteries included. The DSC Batt PGx901-x911 is the replacement battery for this unit and it contains two (2) 3.6 Volt Li-Thionyl Chloride 0-102710. These are the same batteries that are included with the siren when new. These long-life batteries will last from seven (7) to nine (9) years before requiring a replacement. Replacement is very easy as each battery comes with a quick connect/disconnect harness and plug. It is recommended that both batteries be replaced at the same time, as the DSC Batt PGx901-x911 replacement pack comes with two (2) batteries already included for this purpose.
