The TL-SF1008D Fast Ethernet Switch is designed for SOHO (Small Office/Home Office) or workgroup users.. All 8 ports support auto MDI/MDIX, no need to worry about the cable type, simply plug and play. Moreover, with the innovative energy-efficient technology, the TL-SF1008D can save up to 73%* of the power consumption and 70% of the packaging material can be recycled, making it an eco-friendly solution for your business network.
TL-SF1008D Fast Ethernet Switch provides 8 10/100Mbps Auto-Negotiation RJ45 ports. All ports support Auto MDI/MDIX function, eliminating the need for crossover cables or Uplink ports. Featuring non-blocking switching architecture, TL-SF1008D forwards and filters packets at full wire-speed for maximum throughput. With 10K Jumbo frame, the performance of large files transfers is improved significantly. And IEEE 802.3x flow control for Full Duplex mode and backpressure for Half Duplex mode alleviate the traffic congestion and make TL-SF1008D work reliably.
This new generation TL-SF1008D Fast Ethernet Switch features the latest innovative energy-efficient technologies that can greatly expand your network capacity with much less power. It automatically adjusts power consumption according to the link status and cable length to limit the carbon footprint of your network.
It also complies with the EU’S RoHS, prohibiting the use of certain hazardous materials. Besides, 70% of the packaging material can be recycled.
The auto features of this switch make installation plug and play and hassle-free. No configuring is required. Auto MDI/MDIX eliminates the need for crossover cables. Auto-negotiation on each port senses the link speed of a network device (10, 100 Mbps) and intelligently adjusts for compatibility and optimal performance.
A fire alarm is a an electronic sounder or a bell. The sounder makes a loud high pitched sound to alert people that there is a fire in the building. The sounders can be programmed to sound different tones. Most fire alarm sounders in Europe sound like a siren. The bell makes a continuous ringing sound.A fire alarm system has a number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are present. These alarms may be activated automatically from smoke detectors, and heat detectors or may also be activated via manual fire alarm activation devices such as manual call points or pull stations. Alarms can be either motorized bells or wall mountable sounders or horns. They can also be speaker strobes which sound an alarm, followed by a voice evacuation message which warns people inside the building not to use the elevators. Fire alarm sounders can be set to certain frequencies and different tones including low, medium and high
CLORIDE UK is a Photoelectric Smoke Sensor, which is fully compatible with ESP Analogue Addressable Protocol. The ALG-EN is available in ivory, white or black, the black version (with matching black base) is ideal for nightclubs and cinemas where attention to aesthetics is required.
The ALG-EN incorporates Hochiki’s newest High Performance Chamber Technology removing the need to use Ionisation Smoke Sensors in the majority of applications. This also allows the sensor threshold level to be increased, thereby improving the signal to noise ratio and reducing susceptibility to false alarms.
The ALG-EN smoke chamber is easily removed or replaced for cleaning and utilises a unique improved baffle design which allows smoke to enter the chamber whilst keeping out ambient light.
