DualCom Mounting
DualCom may be mounted in a boxed power supply or other suitable case. The
CS1520 and CS1530, grade 2 and 3 power supplies are ideal for this. The case
has mountings and screw retainers for a DualCom, space for 7 amp/hour battery(s)
and plenty of room for wiring.
Alternatively, any suitably sized case that meets the security requirements
may be used. DualCom has two mounting lugs fitted to its case for screw
fixing.
Security
Note: Up/downloading security features are NOT activated when
DualCom is supplied. Use of one or more of these features is recom-
mended.
DualCom should be protected from assault and tampering by being fitted inside
a tamper protected enclosure that is 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 an
NVM Programming Socket connected to a PC.
A ’call-back’ GSM 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
requires this code whenever up/downloading is requested.
CSL strongly rec-
ommend that this feature is used.
In addition, up/downloading can be inhibited when the alarm system is in the
set state.
Note: Up/downloading security features are NOT activated when
DualCom is supplied. Use of one or more of these features is recom-
mended.
