In this video, Dylan from Alarm Grid discusses the Qolsys IQ Panel 4's built-in siren dB rating. The panel has four (4) speakers that, together produce an 85 dB alarm sound for burglary, fire, carbon monoxide and any other type of audible alarm. For silent alarms, such as some panics, there is no alarm sound.
A sound at an 85 dB measurement is about as loud as a semi-truck traveling 40 MPH heard at a distance of 50' (15m). It's loud enough to startle and deter a burglar, but it is not loud enough to damage hearing, as long as exposure is not for too long or too often. For louder options, there are a number of options available.
The Qolsys IQ Siren is a Z-Wave siren that plugs into a standard outlet. It has its own backup battery that charges when AC is present, but if AC power is lost, then the battery can power the siren. It has a rating of 105 dB. Because the decibel scale is logarithmic, each 10 dB increase in sound is ten times as loud as the previous rating. So 95 dB is ten times as loud as 85 dB and 105 dB is 100 times as loud as 85 dB (10 x 10).
If you plan to add a wired-to-wireless converter module you may have additional options for adding wired sirens. The DSC PowerG wired to wireless converter modules support a siren and provide up to 700 mA of current. In this video, we show you a blue strobe light that has been activated by a DSC PG9WLSHW8 converter module that is programmed with the IQ Panel 4.
If 700 mA of current isn't sufficient, then a relay and a power supply can be added. Likewise, the Qolsys Hardwire 16-F can also add support for a wired siren, though it provides only 500 mA of current. But again, if that is insufficient, a relay and a power supply can be added.
