Regulatory Constraints
Before attempting to install DualCom, the installer must be aware that the
CS2300 range of DualCom products may only be installed by a professional
installer.
The Ringer Equivalence Number (REN) of the apparatus is 0.3. The sum of
RENs of the individual items connected to one PSTN line should not exceed 4.
Intended Use
DualCom is designed for use as a signalling device for use with intruder, fire and
similar alarm systems. It will create messages when triggered by the changing
voltage situations on DualCom's input terminals, and it will send these to an
ARC receiver when a communication path is established via radio or wired
means.
Users are advised that the intended use should avoid situations where the rate
of triggering exceeds the rate at which messages may be sent to, or received
by the ARC's receiver.
DualCom includes a 'message memory' that will hold messages as they are
triggered by DualCom's input terminals. When a path to an ARC receiver is
established, the messages will be sent from the 'message memory'. When the
'message memory' is full of messages waiting to be sent then further triggering
of DualCom's inputs will create no further messages.
