Notification appliance circuit wiring (TB2)
The control panel provides either two or four notification appliance circuits depending on which
model you have. Each circuit can be individually configured for continuous, temporal,
synchronized, coded, or city tie output.
Circuit specifications
• Class B or Class A.
• Circuit voltage: 24 VFWR, regulated
• Circuit current
• VS1 panel:
3.75 A total, 2.5 A max. per circuit at 120/230 VAC 60 Hz input voltage
3.0 A total, 2.5 A max. per circuit at 230 VAC 50 Hz input voltage
• VS4 panel:
6.0 A total, 2.5 A max. per circuit at 120/230 VAC 60 Hz input voltage
5.0 A total, 2.5 A max. per circuit at 230 VAC 50 Hz input voltage
• Max. resistance: 26 Ω total
• Max. capacitance: 0.35 µF
• EOLR: 15 kΩ, 1/2 W (P/N EOL-15), ordered separately
• Synchronization: For NACs wired Class A or Class B, signal synchronization is supported
system-wide (all NAC circuits).
• Ground fault impedance: 0 to 5 kΩ
• Power-limited and supervised
Notes
• On the VS1 panel, Class A wiring is available only when the optional SA-CLA expansion
card is installed. Refer to the SA-CLA Class A Interface Card Installation Sheet
(P/N 3101094-EN) and to the topic “SA-CLA wiring” on page 26.
• Listed EOLRs must be installed as shown for proper supervision.
• Marking indicates the output signal polarity when the circuit is active. Polarity reverses
when the circuit is not active. Wire notification appliances accordingly. Notification
appliance polarity is shown in the active state.
• Installation limits are subject to acceptance by the AHJ.
• If the riser is used for more than one notification zone, install in accordance with the
survivability from attack by fire requirements in NFPA 72 National Fire Alarm and Signaling
Code.
