Analogue addressable fire systems are becoming increasingly I/O intensive as more functionality is incorporated into fire detection systems.

Sensor manufacturers generally have a good range of "I/O" modules available, however the number of inputs and outputs is sometimes limited with I/O intensive applications requiring several large and expensive modules mounted or installed at a single location. Syncro "I/O" offers a cost effective solution.

The Kentec Syncro system was conceived with the growing need for I/O in mind and can provide an additional 512 channels of network wide, configurable I/O on each individual control panel via an onboard RS485 bus.

A range of modules are available to suit different applications can be mounted locally or up to 1200 metres away as follows:

16 channel I/O board – S560
16 channels each of which can be configured as an opto isolated input or an open collector outputs. Ideal for driving LED mimic panels or conditioning switch inputs.

The next time you need to specify I/O on a system, remember there is an alternative to the costly and bulky modules you would normally use and contact Kentec technical sales for advice on other options.
