Communication is Key!

By | Laboratory Control

All American Gas Safety panels have built in connectivity. Let’s take a look at how this helps the mechanical engineer when specifying a classroom utility control.

The Merlin 1000SW+ which controls Gas, Water and Electricity whilst also testing the gas pressure before and during operation has built in connectivity allowing the panel to communicate with the schools BMS and has connections for the buildings existing fire alarm system. The panel can either tell the BMS that the gas is “ON” or “OFF” or with the flick of a switch on the internal control panel it can tell the BMS that the panel has gone into “Alarm” or “shutdown” mode due to low pressure, high concentrations of CO2, gas leak detected or that an EM stop has been actuated.

Remember those hot and humid days at school, where your eyelids felt heavy and you couldn’t concentrate. I used to blame it on the boring old teacher, or the fact it was such a lovely day outside. Well now we know different.  Hundreds of studies have investigated the effects of bad ventilation in classrooms and the effect on student school work performance.

Most studies tend to concentrate on the CFM (cubic feet per minute) of the ventilation, or ACH (air changes per hour). But what are they changing out? What is being ventilated away from the students? Read More
