: GENERAL REQUIREMENTS:
If PoE is not being used, then use only UL-listed, access control, power-
limited power supplies with an ‘AC on’ indicator light clearly visible on the
enclosure. ISONAS recommends that Power supplies should provide at least
four hours of standby power.
Never connect power supplies to a switch-controlled receptacle.
Install the ISONAS system in accordance with the National Electrical Code
NFPA 70. (Local authority has jurisdiction.)
Use only wire or UL-listed cabling recognized as suitable for ISONAS power
supply and data communications, in accordance with the National Electrical
Code.
Where possible, separate ISONAS equipment and cabling from sources of
electromagnetic interference (EMI). Where this is not possible, take other steps
to reduce the effect of EMI on cabling or equipment.
Protect input and output terminals adequately from transient signals. Also,
connect these terminals to power-limited circuitry.
