Installation
Figure 7 Independent Zone Control Within Protected Premises
Wiring the D269 Keypads
You can wire up to four D269 Keypads in parallel to the D268 Module (see Figure 4). You must install at least one
D269. A cable with a four pin connector and four wire leads is supplied with each keypad. The furthest D269 can
be located a maximum of 500 feet away from the panel enclosure. Using a larger gauge wire does NOT increase
this distance.
UL certificated installations: UL certifications require a D8108A Attack Resistant Enclosure, and a 1 Amp in-line
fuse (Radionics model D201, supplied with the D268 Module) on the red power supply wire. Only one fuse is
required per D268/D269 sub-system.
D268/D269 Configurations
You can use the D268 and D269 in several sub-zone applications. Figure 7 shows a typical configuration of the
D268 and D269 protecting a sub-zone within the main protected premises. You can locate the D269 either inside
or outside of the protected area. Protected wiring (Figure 5) is not required for this application.
Figure 8 shows a D269 located outside the main protected premises. As in the previous case, the D269 can be
located either inside or outside of the protected area. Protected wiring (Figure 5) is required for this application.
