Current Loop 1 & 2 (RMA-CL1-SEN & RMA-CL2-SEN)
Early versions of the Room Alert 12E have this polarity reversed: LEFT = negative (-),
and RIGHT = positive (+). If you observe your voltage value flipping back and forth
from “0” to “5,” it’s likely that the speaker wires simply need to be inserted in the
opposite contact.
Room Alert models 32E and 12E have built-in analog input ports; Room Alert models 32E,
24E, 12E, 4E & 3E can also interface with analog sensors through AVTECH’s Temperature
& Analog Sensor, which connects to Room Alert’s Digital Port. For more information
about AVTECH’s Temperature & Analog Sensor, please see its Installation Note, visit
or contact a Product Specialist.
