The MTL5526 enables two separate IS circuits in a hazardous area

to be relay-contact controlled by two on-off switches or logic signals

in a safe area. Applications include the calibration of strain–gauge

bridges; changing the polarity (and thereby the tone) of an IS

sounder; the testing of IS fire alarms; and the transfer of safe-area

signals into an annunciator with IS input terminals not segregated

from each other. The output–relay contacts are certified as non–

energy–storing apparatus, and can be connected to any IS circuit

without further certification, provided that separate IS circuits are

such that they would remain safe if connected together.
