SDD-S65(-RAC) and SDD-OE65(-RAC)

The detector comes in two different types: one optical (SDD-OE...) and one ionisation (SDD-S65...). Both types are available with or without relay. They are intended for use together with Regin’s ABV... series of control units. The RAC models have a relay and are not to be connected to Regin’s control units ABV... The built-in relay makes it possible for the unit to independently give an alarm without connection to a control unit. A 540 mm aluminium venturi tube is delivered with the detector. The tube can be shortened to fit more duct sizes. The detector housing has a window giving a clear view of the flow indicator and the alarm LED. The detectors are approved according to EN54 and have been tested and approved by SBSC. The detectors have a built-in service alarm function for sensing the dust and dirt accumulation which inevitably occurs over time. When the degree of dirt has reached the level at which there is the risk of false alarms, a service alarm is given indicating that cleaning is required. The detectors should be tested and cleaned yearly to ensure proper function. The function of the detectors can be tested by using test smoke. The cover can be cleaned with a vacuum cleaner.
