Rate-of-rise detector ES Detect
Description
The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip providing a network (IP) stack capable of both TCP and UDP. The Arduino Ethernet Shield supports up to four simultaneous socket connections. Use the Ethernet library to write sketches which connect to the internet via a standard RJ45 Ethernet jack using the shield.
The latest revision of the shield adds a micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Uno and Mega (using the Ethernet library). You can access the on-board SD card slot using the SD library which is included in the current Arduino build.
The latest revision of the shield also includes a reset controller, to ensure that the W5100 Ethernet module is properly reset on power-up. Previous revisions of the shield were not compatible with the Mega and need to be manually reset after power-up. The reset button on the shield resets both the W5100 and the Arduino board.
Arduino communicates with both the W5100 and SD card using the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on the Duemilanove and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W5100 and pin 4 for the SD card. These pins cannot be used for general i/o. On the Mega, the hardware SS pin, 53, is not used to select either the W5100 or the SD card, but it must be kept as an output or the SPI interface won't work.
System benefits:Optimally matched to the ES Line systemWith multisensor detectors for the detection of all fires, even under the most difficult operating conditionsUp to 30 detectors per detection groupReliable detection:Uniform response sensitivity of the detector for all different types of fire for the multisensor detectorsLarge distance between signal and interference magnitudes due to special sensor and electronics design for suppressing electromagnetic influencesAutomatic adaptation to varying environmental influencesElectronic compensation also called drift-compensation of long-term influences of contamination or agingReliable false alarm suppression:High reliability against false alarms by temporal evaluation of different sensor criteria, with built-in insect screen and sealed against rear air flow entryExclusion of signal forms not typical of fires through special filter algorithmsAutomatic self-monitoring of the detector electronicsAutomatic self-monitoring of sensors for function and conditionMaintenance:Designation of the heat detector by a black ring on the light pipeHours of operation, alarm and fault counter in each detectorOperation data retrieval of all detectors of a group with standard service PC and field bus interfaceDetector LED for alarm display and as an identification display in the service (for maintenance with 8000 tools)Wide range of accessories:Standard socket and relay baseSocket adapter for ceiling installationDust caps optional for fire detectors and detector baseKit for suspended mounting
