Definitions
- the invention is directed to a room surveillance sensor with integrated in a common housing according to different smoke and working physical principles Temperature sensors as well as with one or more interfaces for connection to a fire alarm and / or building control center for the transmission of the sensor measurement signals.
- Automatic fire detectors are often equipped with smoke sensors built up, which operates according to the light barrier principle in an atmosphere filled with smoke Transmittance of a light beam is reduced, which of a light sensitive element is detected and an alarm triggers.
- smoke Transmittance of a light beam is reduced, which of a light sensitive element is detected and an alarm triggers.
- one or more Sensors designed in this way and the relevant measurement signal area (s) is (are) chosen such that a continuous Measured value acquisition, processing and forwarding over the entire, usual range of monitored Size (s) up to the danger zone. in this connection is therefore next to the actual danger zone, in which also known multisensors for the purpose of generating a Alarm signal, also the usual range of the monitoring quantities recorded.
- a moisture sensor For example, provide a positive indication that a Condensation on the optical lens system of a smoke sensor fear.
- a motion detector can provide additional information about whether smoke development, for example Can be attributed to smokers. Such can also be Use additional information for climate control, a motion sensor in particular being used for this can determine the presence of people in a room and then the temperature setpoint of the air conditioning or heating system to raise a few degrees.
- At least one Interface meets fire protection requirements. Since the primary application of the invention The sensor is located in the fire detection area, requires use of a room surveillance sensor according to the invention in a prescribed by building authorities and / or insurance companies Fire alarm system compliance with legal requirements, especially at the interfaces.
- the building control center can be used for climate control necessary measured values either via the fire alarm control panel received or by a direct coupling of the concerned room monitoring sensor to an installation bus of the building management system. For the latter case a corresponding interface on the room monitoring sensor to be available.
- the invention is further characterized by one or more Digitization modules for the transmission of the measured values as digital values.
- Digitization modules for the transmission of the measured values as digital values.
- the invention further provides one or more multiplex modules for transmission of the measured values in multiplex technology in front. This makes it possible to use a single, for example Connection made two-wire line the measured values of several Transfer sensors, so the installation effort is further reduced.
- a building block can also be designed as an intelligent communication module, from a fire alarm and / or building control center a specific address is addressed and then the measured value transmits one or more sensors.
- a microprocessor to control the communication of the sensors with of the connected center (s).
- This microprocessor can also simultaneously evaluate the different Transfer measurement signals from the existing sensors be as well as deciding whether an exceptional case the intervention of the fire alarm or building control center requires.
- further provision can be made be that the microprocessor to send an emergency call prompted the relevant center to do the same so early is informed of the exceptional situation as possible and appropriate countermeasures can be initiated.
- the core of the room surveillance sensor 1 is a smoke sensor 2, for example after an optoelectronic Principle works, as well as a temperature sensor 3, for example. is constructed as a semiconductor sensor.
- These sensors are according to the invention designed such that their output signals 4, 5 within a wide range of monitored, physical Size are proportional to the monitored size.
- the temperature sensor 3 can also have temperatures around or even below of the freezing point exactly, while the smoke sensor 2 already recorded the smallest cloudiness in the room air. This However, high sensitivity can be achieved with a simpler one Embodiment also limited to one of the two sensors his.
- the output signals 4, 5 of the sensors 2, 3 become a processing module 6 supplied, the signals on one specified range, e.g. 0 ... 10 V or 4 ... 20 mA, or which comprises one or more analog-to-digital converters, around the signals 4, 5 of a digital further processing to make it accessible.
- a processing module 6 supplied, the signals on one specified range, e.g. 0 ... 10 V or 4 ... 20 mA, or which comprises one or more analog-to-digital converters, around the signals 4, 5 of a digital further processing to make it accessible.
- an inventive Room monitoring sensor 1 can in particular be analog current or Voltage signals for forwarding to a higher-level Fire control panel 7 issued at an interface 8 become.
- an intelligent module 9 for example a microprocessor, be installed, the two, processed 6 sensor signals 4, 5 evaluates, possibly linked to each other and possibly can generate an emergency call to the fire alarm center 7.
- This microprocessor 9 can also be used to create a To control communication module 10, which is also optional is.
- the communication module 10 can have its own intelligence be equipped and for example from the fire alarm center 7 addressable memory locations in which the processed 6 sensor measurement signals 4, 5 for a query by the Fire alarm center 7 are provided.
- Communication module 10 for example, one or more modulation modules to use the different measured values different carrier frequencies over the same two-wire line 8 to be transmitted to the fire alarm control panel 7.
- the measured value signals 4, 5 also interesting for a building control center 11. This can the corresponding measured values 4, 5 either through communication 12 with the fire alarm center 7 or procure them communicates directly, i.e. via its own Interface 13 with the room surveillance sensor according to the invention 1 to get the information you need first hand receive.
- both sensors 2, 3 a fire hazard
- an emergency call sent 8 to the fire alarm control panel 7 senses only the temperature sensor 3 an increase in Room temperature, a corresponding message can be sent to the building control center 11 to be issued 13.
