Description
The ALK alarm and ventilation box uses the built-in RTC trigger to activate disposable CO2 one-way bottles. The RTC trigger can be activated by manually pressing the trigger button, by activating the electromagnet or by activating the pneumatic trigger. The valve is located behind a glass sheet, which is smashed in for manual activation in the event of an alarm. The housing is made of sheet steel and is available in either orange (RAL2011) or red (RAL3000). The operating status is visualized via the integrated visual display.
The box is prepared for a 6 mm pipe connection as standard, but is also available for an 8 mm pipe connection on request.
The standard CO2 bottle thread is 1/2” UNF. We recommend the use of our CO2 bottles up to 1500 gr.
In addition, the ALK alarm and ventilation box contains a built-in priority and ventilation valve that can be configured with other attachments, allowing it to be controlled for example via a wind and rain control system. The desired operating pressure for ventilation can be set via the built-in filter regulator with operating pressure gauge, water separator and condensate drain plug.
