Abstract
The invention relates to an alarm valve station for a fire alarm system, having an alarm valve with an extinguishing fluid inlet and an extinguishing fluid outlet, wherein the alarm valve is set up for selectively releasing or blocking the extinguishing fluid flow between the extinguishing fluid inlet and the extinguishing fluid outlet, having a pressure sensor which is in a fluid-communication with the alarm valve and which is configured to detect a change in pressure and for converting this into an electrical alarm signal, and having an alarm delay device for delaying the alarm signal. It is proposed according to the invention that the alarm delay device is designed as an electrical alarm delay device and is connected in signal-communication with the pressure sensor.
Claims17
A valve station, comprising:
- a valve having an extinguishing fluid inlet and an extinguishing fluid outlet, an internal sealing surface disposed between the extinguishing fluid inlet and extinguishing fluid outlet, an internal alarm channel disposed between the internal sealing surface and the extinguishing fluid inlet, and a block member that contacts the internal sealing surface to selectively release or block an extinguishing fluid flow between the extinguishing fluid inlet and the extinguishing fluid outlet,
- an alarm line without a shut-off member in fluid communication with the internal alarm channel,
- a mechanically operated alarm device in fluid communication with the alarm line without a shut-off member,
- a pressure sensor in fluid communication with the alarm line without a shut-off member, the pressure sensor configured to detect a change in pressure in the extinguishing fluid flow and to convert the change in pressure into an electrical alarm signal,
- an electrically operated alarm device in signal-communication with the pressure sensor configured to receive the electrical alarm signal, and
- an electrical alarm delay device configured to permanently prevent a forwarding of a received electrical alarm signal or discard a received electrical alarm signal.
