Strobe Appliance Circuit Connections
The strobe appliance circuit consists of a NAC (9 to 31VDC) input and a supervised NAC (24VDC)
Output. As described in Table 3-1 on Page 3-3, the strobe output provides a synchronized output for
compatible Wheelock, Inc. synchronized strobes. When a synchronized signal from a previous
module is used open Jumper W2 (See Figure 3-15, Page 3-15). This also allows for pass through of
the synchronized NAC Circuit on the RET connections. See Figure 3-1, Section 2 on Page 3-2 for
location. Figure 3-3, below, is an enlarged picture of the referred area.

Strobe Input and Output Connections
1. Connect strobe appliance circuit to Strobe NAC Circuit output STB OUT connection on TB2.
Observe correct polarity. See Figure 3-1, Section 2 (Page 3-2) for location. Figure 3-3 is an
enlarged picture of the referred area. The Strobe Appliance Output NAC Circuit is supervised. A
UL Listed 10K Ohm, ½ W EOLR is required at the end of the circuit for proper supervision.
NOTE: The strobe output circuit can be activated two ways. If the strobe output is to be
activated when one or all the digital voice messages are initiated, operate DIP switch SW2 as
explained in Table 3-2 on Page 3-16. The second way is to connect a NAC circuit input from
an FACP to STB IN as described in step 8 below
2. Connect Strobe NAC Circuit input (9 to 31VDC) from the FACP or other UL Listed control panels
to the Strobe Input circuit (STB IN) connection on TB2. Observe correct polarity. See Figure 3-1,
Section 2 for location. Figure 3-3 is an enlarged picture of the referred area.
3. Connect the FACP EOLR, additional appliances or additional SP40/2 panels to RET connection
on TB2. See Figure 3-1, Section 2 for location. Figure 3-3 is an enlarged picture of the referred
area.
