1. Introduction
The i-on16 is a wireless intruder alarm system intended mainly for use in
domestic and small commercial properties.
The heart of the i-on16 system is the control unit and its keypad. The
control unit contains the main wireless receiver, the power supply and
stand-by battery. The stand-by battery can keep the alarm system going for
up to 12 hours if the mains supply fails.
Connected to the control unit by cable are the keypads. The keypads each
have a two line display to show you status information, and various keys for
operating the system. The keypads also contain a speaker to give warning
tones when the system is setting or unsetting. Beginning in 2013 there are
two styles of keypad, both performing the same function.
Users identify themselves to the system by keying in access codes. If they
do not wish to use access codes then the keypads also contain proximity
tag readers, allowing users to identify themselves by means of small
electronic tags that they carry with them.
In addition to and access code or proximity tag, each user can be assigned
one portable four-button remote control and/or one two-button hold up
alarm.
To protect an area the control unit can operate a range of detectors.
Detectors can be connected to the control unit or expanders by wires, or
communicate to a radio expander using a small radio transmitter. Figure 1
shows some examples. In addition to fixed detectors the control unit can
also monitor small portable transmitters that users can employ to start
alarms remotely, for example in the case of a Hold Up Alarm.
(Hold Up Alarms are also known as Panic Alarms.)
When the control unit detects an alarm, it can start an external
sounder/strobe unit by sending the appropriate radio signal. In addition the
control unit can also communicate using a variety of plug on modules.
Some modules also provide speech recording and playback facilities so
that the system can send recorded speech messages to pre-programmed
telephone numbers.
The control unit and expanders also provide sets of connectors for outputs,
which the installer can use to link the control unit to siren/strobe units or
other equipment.
