The MTL2215 enables either one or two separate IS circuits in a hazardous area to be relay-contact controlled by a single on/off

switch or logic signal in a safe area. Applications include the calibration of strain-gauge bridges, changing 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-energystoring’apparatus, and can be connected to any IS circuit without further certification, provided that separate IS circuits are such that they would still remain safe if connected together.
