Power (TB4)
Notes:
1) This arrangement allows use of the UDACT-F simultaneously with the RTM-8F module.
2) Ferrite cores are recommended for all applications.
3) Recommended wire is 12 AWG to 18 AWG twisted/shielded pair.
4) If shielded wire is used, connect only one end of shield:
a) shield may be connected to cabinet (earth ground) at fire alarm panel, or
b) shield may be connected to TB1 Terminal 5 (Shield) at UDACT-F. NOTE: The shield
end that is not connected should be insulated to prevent accidental grounding. Do not
connect both ends of shield under any circumstance since a ground fault may result.
5) Conduit is recommended for external wire runs. Consult local building codes.
6) Connect Ground Strap (supplied with ABS-8RF enclosure) from Earth Ground terminal on
UDACT-F to a solid building earth ground. Conduit alone will not provide a reliable earth ground.
7) UDACT-F may be located up to 6,000 feet away from the host control panel.
8) Refer to Specifications Section for power requirements.
9) UDACT-F TB1 Terminals 6 and 7 are for future use.
