February 2011 2-36 P/N 06-237041-001
Both NAC circuits are supervised, power limited, and are compatible with conventional, UL-Listed,
24-Vdc notification appliances such as:
• MT Series Multi-Tone Horns and Horn/Strobes
• NS Series Horn/Strobes
(See Note 1)
• NH Series Horns
• RSS(P) Series Strobes
(See Note 1)
• Exceder Series
(See Note 1)
• Commander Series
(See Note 2)
NOTE 1: These strobes can be programmed for synchronization.
NOTE 2: Commander Series strobes require the manufacturer’s synch module to synchronize
devices.
Horn/strobe combination devices utilizing the appropriate synch protocol have the option to use
silenceable horns and non-silenceable strobes. Refer to the horn/strobe manufacturer’s installation
sheet for details.
Use Figure 2-31 to estimate the maximum length of wire as a function of notification-appliance
current for NACs.
Figure 2-31. Wiring Length vs. Notification-Appliance Current
WARNING
All strobes are designed to flash with continuous applied voltage. Strobe notification
appliances cannot be used on pulsing signaling (NAC or R-NAC) circuits. You must use a
separate notification circuit if the application requires a pulsing signaling circuit for
horns. Failure to adhere to this warning may cause system malfunction.
