Instruction manual

CAUTION: The National Electric Code limits the maximum number of conductors that can be
installed in conduit and wiring boxes depending on the size of the conduit, the volume of the
boxes, and the gauge of the wire used. Make sure that wiring used for installation complies with
the latest NEC, NFPA, Local, State, County or Province requirements.
Field Wiring Connections
All wiring terminals are designed to accept #12 AWG through #18 AWG wiring for one wire
per terminal or #16 AWG to #18 AWG for two wires per terminal. Proper wire gauge
considerations for the Notification Circuit must take into account current requirements versus
length of run.
NOTE: Only speakers with DC blocking capacitors will provide for proper speaker
supervision.
Visual Notification Appliance Output Wiring (SPB-80/4)
Wire gauge selection involves consideration of all factors including, wire loop length, maximum
current draw of each appliance, number of appliances, and maximum voltage drop allowable.
The SPB-80/4 has two strobe NAC circuits, while the SPB-160 has none.
• Each strobe NAC has a 24VDC, 2.0 Amps maximum output.
• Strobe NAC meets Class B supervision requirements for notification appliance circuits.
• The strobe output circuit shall have a UL Listed 10K Ohm, EOLR installed across the last
visual notification appliance. If the output is unused, a UL Listed 10K Ohm, EOLR shall be
placed across the output terminals.
Speaker Notification Appliance Output Wiring
Wire gauge may vary for each audio appliance output on the panel. When:
• Speaker (with transformer) appliances are used with supervised audio amplifier module.
Wire gauge selection should involve consideration of all factors including, wire length,
appliance power ratings, and the number of appliances.
• The two amplified outputs are either a selectable 25V or 70.7V audio output, rated for 80
watts maximum. The SPB-80/4 has one audio output, while the SPB-160 has two.
• The output meets Class B supervision requirements for notification appliance circuits.
• The audio output circuit shall have a UL Listed 10K Ohm, EOLR installed across the last
notification appliance. If the output is unused, it shall have a UL Listed 10K Ohm, EOLR
across the output terminals.
