SATEL Installer Manual 19

The control panel only supports the modules which are registered in the system by means of

the EXPANDER IDENTIFICATION service function (SERVICE MODE ÆSTRUCTURE ÆHARDWARE

ÆIDENTIFICATION ÆEXPANDER IDENT.). The function saves to the module memory a special

(16-bit) number, which is used for checking the module availability in the system. The number

is stored in EEPROM non-volatile memory and can only be changed after restarting the

expander identification function. Hence, it is impossible to substitute another module for the

identified one (even if a correct address is set in it). Substitution of another module for the

identified one will trigger alarm (module tamper – verification error). Each change of module

or module address requires restarting the expander identification function.

Notes:

• The control panel will not support the module unless the identification function is

completed with the "Found xx exp. (yy new)" message.

• A wrong module connection can make correct identification of the modules impossible,

which is signaled by the message: “Error! Two expanders have the same addr!".

• Too high resistance of the cables connecting the module to the control panel (large

distance, too small number of wires for a single signal) may result in the module being not

recognized by the identification function.

Fig. 13. Connection of modules without power supply (by the example of CA-64 E zone

expander) to the control panel – the distance between panel and modules is 300 to 600 m.

The modules are powered from a control panel independent source (power supply/expander

with power supply). 2 wires in cable are used for each signal (CK, DT, COM).

3.7 CONNECTING HARDWIRED DETECTORS

The control panel can interface with any hardwired detectors. Each control panel zone and

zones of LCD keypads and zone modules may operate in the following configurations:

• NC (normally closed),

• NO (normally open),
