Notification Appliance Circuits - Honeywell Gamewell FCI ILI-MB-E3 Product Installation Document

3.2 Notification Appliance Circuits

The Notification Appliance Circuits (NACs) are connected from the ILI-MB-E3.
The ILI-MB-E3 provides two, 24 VDC Class A, Style Z or Class B, Style Y
notification appliance circuits. The E3 NAC circuits synchronize the horn and
strobe outputs in the ILI-MB-E3 panels. To enable the NAC Sync Option Feature,
select the Sync Option in CAMWorks. For additional information on the NAC
Sync Option, refer to the CAMWorks Online Help. See Figure 3.2.1 for wiring
information. See the Compatibility Addendum, P/N: 9000-0427-L8, for a list of
approved compatible devices.
ILI-MB-E3 Wiring Designations:
NAC 1 – Style Y
NAC 2 – Style Y
NAC 1 – Style Z
NAC 1 - Style Z
NAC 2 – Style Z
(Polarity markings indicate the polarity of the circuit in alarm condition). Use UL
Listed End-of-Line Resistor EOL-N (33K), P/N 4700-0484 for Class B, Style Y
wiring.

Table 3.2.1.1 lists the End-of-Line Resistor settings.
ILI-MB-E3 (Second Generation)
End-of-Line Resistor
For the ILI-MB-E3, use UL Listed End of Line Resistor model
ELR-47K for Class B, Style Y wiring. The model ELR-47K is
supplied with the ILI-MB-E3. A range of other UL Listed End of
Line Resistors may be connected to these NAC circuits if they are
within the specified range listed in Table 3.2.2.1.
Table 3.2.2.1 lists the End of Line Resistor ranges that are available for use.
NOTE: SURVIVABILITY CLAUSE:
Per the National Fire Alarm Code, NFPA 72, all circuits necessary for the operation of the notification appliances shall be
protected until they enter the evacuation signaling zone that they serve. Any of the following methods shall be considered
acceptable as meeting these requirements.
1) A 2-hour rated cable or cable system
2) A 2-hour rated enclosure
3) Performance alternatives approved by Authority Having Jurisdiction (AHJ)
