Function
Part of the air which flows in the ventilation duct [1] is diverted into the flow chamber [2]. The separation plane [3] and the protective screen [4] protect the electronics from soiling in the process. The electronics monitor
the air flow for soiling and particles. Messages can be transmitted to a fire detection system or the building management system so that, in case of smoke detection, the necessary control scenarios can be triggered in good time in order to prevent smoke from transferring to other fire compartments.
The analysis and control unit can be removed and sprayed with a test aerosol for a functional test.
Installation
Installation details
The OR4 can be installed with any alignment in ventilation ducts regardless of the direction of air flow (horizontally, vertically or at an angle). The continual through-flow and thus effective smoke detection must be guaranteed in the process. The corner area on rectangular ventilation ducts must not be used for installation.
In small and medium-sized duct cross sections, installation at the top, side or bottom is possible. In large, horizontal cross sections, installation in the upper third of the ventilation duct is recommendable in the interest of early smoke detection. Installation must be performed at a sufficient distance from connection points, such as plug connections or flanges.
The gap upstream and downstream of disruption points (of all kinds) must be at least 1.5 x d h (hydraulic diameter).
Disruption point
A protective film is fitted in the factory in order to protect the smoke switch and the protective screen from soiling during the construction stage. It must be removed before commissioning.
Installation in circular ventilation ducts
Installation in circular ventilation ducts is shown with the optional saddle pipe.
- Create the installation opening for the installation socket (Ø 94 … 98 mm).
- Connect the connection socket to the saddle pipe, aligning the installation socket to the direction of the air in the process.
- Prick the saddle pipe slightly with the retaining screw, and pre-drill it without the installation socket (Ø 3 mm). Then, fit the installation socket again and secure it with screws.
- Apply sealant (provided by the user) to the saddle socket so that it is airtight.
- Insert the saddle pipe into the installation opening with the installation socket.
- Drill (Ø 3.3 mm) and rivet the fastening holes for the saddle socket.
- Fasten the casing to the installation socket with the analysis and control unit.
- Optional:
A sealing cover can be used to seal the installation socket when the smoke detector has not yet been installed during the construction stage.
Installation in rectangular ventilation ducts
- Measure the centre point of the installation opening and stick on the drilling template.
- Drill the fastening holes for installation of the installation socket (3.3 mm).
- Create the installation opening for the installation socket (Ø 94 … 98 mm).
- Insert the installation socket into the installation opening and fasten it with pop rivets. In the process, align the installation socket to the direction of air.
- Fasten the casing to the installation socket with the analysis and control unit.
- Optional:
A sealing cover can be used to seal the installation socket when the smoke detector has not yet been installed during the construction stage.
