This is taken from our books on Riello and applies to both their oil and gas burners. All of the Riello burners since the 1981 vintage Mectrons and through the models covered in this book have been equipped with alarm contacts. These contacts are line voltage, 120 Vac, so if used with most central alarm boards a switching relay must be used. Most central alarm systems operate on either 9Vdc or 24Vac, so the output from the RIELLO sub-base must be switched to protect the board. When in doubt contact the customer's alarm company. As previ- ously noted, power comes into the RIELLO on terminals "L" (120 Vac HOT) and "N" (120 Vac NEUTRAL), Figure 5-11. When the burner control goes to "LOCKOUT", power (120Vac) will now be present between terminals "L" and "N" and the center terminal which is designated by an X in a circle. If 120 Vac is desired to an alarm or alarm light which is powered by 120 Vac nothing else is required. I'll come back to alarms in another article later on and give you some ideas for gas units. So, that's it, at least for some power burners, and those central alarm options will work with anything, even wood pellets, electric heaters and coal.
