Measure more, wire lessPosted Nov 18, 2011
It's easy to add as many sensors as you need with Climate Guard. Daisy-chaining digital sensors and switch inputs allows you to add sensors without having to run cables all the way back to Climate Guard.
Temperature, humidity and other digital sensors
Climate Guard comes with eight built-in ports for digital sensors, and supports two Sensor Expansion Modules to add up to eight more. By daisy-chaining your sensors, not only can you connect more sensors than you have ports, you can avoid the cost and hassle of running all that extra cabling.
Daisy-chaining is easy. Use a standard 6-conductor phone splitter to connect one sensor to another (Climate Guard supports up to six digital sensors on each port). This is an especially useful way to measure temperature in multiple racks. Burk Technology recommends using two sensors in each rack: one on the top, and one on bottom (to make sure you have adequate airflow). By daisy-chaining, you create one series of sensors rather than having to create "home runs" from each sensor back to Climate Guard.
You can daisy-chain switch inputs, too. By simply splicing the two-conductor cable used for a door contact or other switch input, you can create a "group" of sensors that will all alarm together. For example, you can put door contacts on every rack door, and have Climate Guard send you an alert any time a door is opened. By grouping the sensors in this fashion, not only do you save on wiring, the configuration is a snap because all the senors come into one input.
