Rather than having a xenon strobe as most modern alarms do, this strobe plate has an actual light bulb that illuminates the lens. Unlike a strobe, the light does not flash, unless it is being coded to do so. The appearance of this alarm is like a mix between a System Sensor SpectrAlert Advance and a Gentex Commander 3. This is a very nice control panel with a lot of features and a user interface that is usually only.
