9954 Hardwired Expander
The 9954 hardwired expander provides connectors for eight CCL, FSL or EOL
zones (EOL zones are not relevant for the 9752). Figure 18 shows the layout
of the PCB. See the wiring diagram supplied with the 9954 hardwired
expander for more details.

9960 Radio Expander
The 9960 is a Class VI radio expander. Class VI is the grading given by the
British standard for Wirefree Alarm Systems and is required for signalling
systems that require a police response. It receives signals from the radio
detectors on a frequency of 868.6625MHz.
The 9960 radio expander supports eight or sixteen wirefree zones, depending
on the model ordered. Figure 19 shows the layout of the PCB.
