Security

Note: Up/downloading security features are NOT activated when

Dualcom is supplied. Use of one or more features is recommended.

Dualcom should be protected from physical assault and tampering by being

fitted inside a tamper protected enclosure forming part of the alarm system.

The Dualcom has two independent methods of stopping unauthorised up/

downloading. These security features are for up/downloading only. They do not

operate when the NVM is removed from the Dualcom and is plugged into a

CS1054 NVM programmer connected to a PC.

A ’call-back’ VDN number may be programmed so that the Dualcom always

calls to its preset ’call-back’ engineering number whenever up/downloading is

requested.

A 6 digit access code may be programmed so that the Dualcom always re-

quires this code whenever up/downloading is requested.

In addition, up/downloading can be inhibited when the alarm system is in the

set state.

Note: These up/downloading security features are NOT activated when

Dualcom is supplied. Use of one or more features is recommended.
