[QUOTE="jarance, post: 754157, member: 21"] Yes, it is normal. There is a program that sent a check signal to all the lamps to verify that is it OK or not. To do that, it will send a short ON signal and check the current passing thru the lamps. It the current.amp is within spec, the system will not generate an alarm. If it sense a zero amp, then it will generate a alarm and indicate which lamp or bulb is faulty. [/QUOTE]
