Installing the UTM Universal Tone Module

MISWIRING/ELECTRICAL SUPERVISION — Property damage,
serious injury, or death could occur if independent conductors
are terminated together; both wires of the same polarity must
be used as two separate connections. NFPA 72 requires that
the wires be terminated independently to provide electrical
supervision of the connection.
SHOCK HAZARD — To avoid electrical shock hazards, do not
connect wires when power is applied. Failure to heed this
warning may cause serious injury or death.
For details, refer to the instructions for the Model UTM Universal
Tone Module, doc. No. 2561101.

DO NOT DAMAGE SEALING SURFACES — Property damage,
