Patol reports increased use of ASD 531 aspirating smoke detection system

The ASD 531 is part of the range of aspirating smoke detection systems manufactured by Swiss company Securiton, a business that celebrates its 75th Anniversary this year and for whom Patol is the partner in the UK.

The detector is characterised by its quick commissioning, offering protection for areas of up to 720 m². No training is required, with commissioning achieved in four easy steps to provide effective monitoring of smaller areas and premises where a reduced air sampling pipe network – ie up to 75 metres – is sufficient. Simplicity is ensured through the detector being configured directly on the device, with no need for a PC. 

As is the case with the two larger models – including the highly successful and flagship ASD 535 model – the ASD 531 is equipped with the proven HD detector and large volume smoke chamber. This results in optimum sensitivity combined with a long service life.

In operation, the ASD 531 offers an impressive performance, with any increase in smoke concentration levels detected very early. The display and control panel indicates alarm, fault and status reports, with three fixed pre-alarms and a main alarm, which can be forwarded to a fire alarm control panel.

Restricted access

Steve Wilder (senior account manager at Patol) commented: “The ASD 531 can be used in a wide range of applications, from museums and galleries through to clean rooms and prison cells. Where we are seeing particular growth is in those applications with restricted access such as lift shafts and small switch rooms in telecoms facilities. The unit’s excellent resistance to dust contamination is also a significant advantage in such situations.”

ASD pipeflow software can be used to calculate the required pipe distance and sampling holes (typically Class C with 12 sampling holes, the last being located 40 metres from the detector) to maintain EN 54-20 approval and realise more cost-effective pipe configurations.
