Elements of the IAS

An IAS comprises a control unit in a shielded case, with one to four separate

keypads and various detectors, transmitters and other devices connected to

programmable zones. If required, a keyswitch can be connected to one of the

keypads through a keyswitch interface.

Each control unit has zone connectors on its printed circuit board (PCB).

Separate expanders enable more zones to be connected: each hardwired

expander adds up to eight wired zones and each radio expander adds up to

eight or sixteen wirefree zones (depending on the model used).

This manual covers three models of control unit:

° 9751 8 zones as standard, expandable to a maximum of 24.

° 9752 8 zones as standard, expandable to a maximum of 32.

° 9851 8/16 zones as standard, expandable to a maximum of 40.

Figure 1 shows how these elements are connected in an IAS based on a 9x5x

control unit. In this example, the control unit (14) is directly connected to six

detectors and two door contacts. Further zones are then connected to it

through a hardwired expander (9) and a radio expander (4). There are four

keypads (7 and 11) and a keyswitch (13) connected to one of the keypads.

Note: Only one keyswitch can be connected to a keypad through a keyswitch

interface. However, further keyswitches can be connected as standard

zones, programmed with the appropriate zone type.
