Protec Aspirating Systems Hole Identification Tags
Protec Fire Detection plc is pleased to introduce another first in the aspirating detection systems industry. HIT’s – Hole Identification Tag’s. For many years the practice of drilling different size sampling holes in aspirating system sampling pipes has been the accepted norm. Whilst this method technically gives the correct size orifice for the hole location on the sampling pipe, it is also accepted that this method comes with a degree of tolerance.
In reality the installer usually uses a hand-held drill on a round sampling pipe and therefore it is unlikely that an exact diameter and perfectly straight hole is formed. In addition to this; on many occasions when the drill is withdrawn from the pipe small pieces of the pipe material remain around the hole. This has an impact on the airflow through the pipe by reducing the effectiveness of the hole. Aspirating detection systems are now installed in an ever-increasing variety of different applications, many of which replace standard point type smoke detectors or optical beam detectors.
Often these applications include high ceiling spaces where it is almost impossible to identify where the sampling holes are located and, more importantly, if the sampling hole is the correct size. Protec HIT’s – Hole Identification Tag’s solve all these problems and many more. Each HIT is colour coded to identify its specific sampling hole diameter. This colour coding allows accurate identification of the various sampling hole locations and true hole size for the benefit of commissioning & servicing engineers, clients and even project auditors.
The HIT’s employ a ‘cable-tie’ style securing mechanism around the sampling pipe to allow the HIT to be fixed securely. In addition, a secondary ‘wrap around’ securing mechanism ensures the HIT remains in its chosen location.
Key Features:
Colour coded tags to identify each different sampling hole diameter and location
Viewable distance range approx 20m
Cable-tie securing mechanism around sampling pipe with secondary ‘wrap around’ securing mechanism
Chamfered hole entry to reduce dust loading
Common 8mm diameter drill hole requirement for all sampling hole locations
Accurate identification of sampling hole location and hole size for commissioning & servicing engineers
Integrated to Protec ProFlow 3D sampling pipe calculation program
