Replacement for ASD100 , ASD200 , 330SR 12/24V
The American Sensors / Dicon models ASD100, ASD200 and 330SR low voltage smoke detectors were discontinued by the manufacturer many years ago and they did not launch replacement models.
As an alternative we suggest System Sensor 2012J which is a 4 wire low voltage DC powered smoke detector. As always with any replacement product, you will need to verify that it meets your requirements with your system prior to ordering.
