Definitions
- the invention relates to a triggering device for a Quick-opening valve of a fire extinguishing system, with one Motor containing electromechanical delay device.
- the preamble of claim 1 is based on a triggering device to DE 38 26 300 C2.
- This triggering device has an electric motor that drives a threaded spindle. By a sitting on the threaded spindle, not co-rotating Threaded sleeve is after a certain number of revolutions opened a quick opening valve. The delay time will be by the spindle speed, the thread pitch and the spindle length determined and is thus given constructive.
- the invention is based on the object, a triggering device of the type mentioned, in which the delay time is easily adjustable and during the pre-warning time a secure expiry of the delay time is guaranteed.
- the deceleration device is a stepper motor, which is powered by a Stepper motor control is applied with pulses, the Pulse / pause ratio of the pulses for determining the delay time is changeable.
- the delay device is a stepper motor controller is controlled, which with a in a fire alarm and Control center arranged controller exchanges data telegrams, wherein an operation of the stepping motor is only started or is continued when a predetermined number of trigger telegrams received from the stepper motor controller and as was correctly assessed.
- This will provide security against False triggering increased. Only if the telegrams are received correctly starts the electromechanical delay device and runs to the end position to the quick-opening valve trigger.
- unwanted or undefined electrical Pulses e.g. in case of lightning or overvoltage the electromechanical delay device does not start or she stops immediately and runs to the starting position back. This can cause unwanted extinguishing system releases be avoided.
- the invention also deals with the function monitoring the alarm devices by the control center. For this an operating current is sent through the alarms and only then, if the operating current within given values is located, the alarm is found to be intact.
- the electromechanical Delay device may only be activated if at least one of the audible alarms is intact is and has been put into operation. Should both alarms be out of order, runs the electromechanical delay device not on. Should all alarms during the pre-warning time fail, stops the electromechanical delay device and returns to the starting position.
- a fire alarm and control center 10 To a fire alarm and control center 10 are several (not shown) fire detector connected.
- the fire detectors deliver a fire detection signal via a line 11.
- This Fire detection signal is fed to two alarm circuits 12,13, each one output circuit 14 and a measuring circuit 15 and an acoustic alarm 16 included.
- the output circuit 14 delivers in the event of an alarm via a line 17 continuously an operating current to the respective alarm transmitter 16. The size of this operating current is determined by the measuring circuit 15 monitors the proper functioning of the alarm device determine. Via a reporting line 18 supplies each measuring circuit the result of monitoring to a controller 20.
- the controller 20 communicates with an external valve controller 21, which spatially on a (not shown) Quick opening valve of a fire extinguishing system is arranged.
- the quick opening valve is a valve, the extinguishing gas in the Fire can flow out.
- the valve controller 21 includes an electromechanical deceleration device 22 of a stepper motor 23 and a mechanical Moving device 24, e.g. a spindle drive.
- the Moving device 24 opens the quick-opening valve when it moves by the stepper motor 23 by a defined amount has been. The movement requires a predetermined number of Shift steps of the stepping motor 23.
- the stepping motor 23 is driven by a stepper motor controller 25.
- the stepper motor control 25 provides pulses with selectable Pulse / pause ratio. The pulse pause ratio or the Frequency of the pulses indicates the delay time in which the Movement device 24 from the starting position to the release position is brought.
- the stepper motor controller 25 is via supply lines, via which a supply voltage of 24 V is transmitted with connected to the controller 20 and also via data lines 27, be transmitted via the data telegrams in both directions can.
- the stepper motor controller 25 includes for this purpose a serial data interface.
- the data telegrams are used to check the functionality the communication path between controller 20 and Stepper motor control 25 and also the verification of the reliability the connected components. In the case of triggering the data lines transmit 27 trip telegrams. After this Start the electromechanical deceleration device 22 must For example, 10 trip telegrams per second from the Fire alarm and control center 10 is sent to the valve control 21 become. If the trip telegrams are missing, the electromechanical delay device 22 and moves into the Starting position back.
- the release of the electromechanical delay device occurs only if at least one of the alarm 16 on its functionality has been checked and alarm generated.
