Output devices
Devices such as indicators, lighting systems or third-party equipment can be switched on
or off using "outputs" available from the i-on system. You can configure outputs in the
Installer menu to control the external devices when, for example there is an alarm in a
specified zone, mains is disconnected or a combination of specified conditions occur.
The following types of output are available:
Wired outputs. These are available on some control units, keypads, expanders and
remote power supplies, depending on the model used. Table 1 shows the number of
wired outputs available on each control unit. There are two types of wired output:
o
Transistor (open collector)
– By default, these are switched negative (from 12Vdc
to 0V) when active; you can program them to be switched positive (from 0V to
12Vdc).
o
Relay
– These provide voltage-free changeover contacts. You connect one side
of the external device to the C (Common) terminal, and the other to either NO
(Normally Open) or NC (Normally Closed) side of the relay, depending on the
application.
Radio outputs. These connect directly to a control unit that has built-in radio
communications, or to a radio expander.
Dedicated outputs on the control unit for a siren/strobe unit (not available for i-on
Compact)
– see the next section.
Plug-by outputs (not available for i-on Compact or i-on30R+), used for communicating
alarms to an Alarms Receiving Centre (ARC); see page 15.
Sounders
Sounders indicate alarms, entry tones, exit tones and other conditions. A sounder is built
into the i-on Compact control unit and into all types of keypad except the i-RK01. There
are various types of additional sounders, as described next.
External wired siren/strobe units
All control units except i-on Compact provide connections to drive a standard wired
siren/strobe unit in Self-Activating Bell (SAB) or Self-Contained Bell (SCB) mode.
Expanders also provide connectors for additional external wired sounders.
The following external wired siren/strobe units are supported:
SDR-WEXT-G2
Wired Grade 2 Siren.
SDR-WEXT-G3
Wired Grade 3 Siren.
Third-party units
With compatible connections.
External radio sirens/strobes
Radio siren/strobe units can communicate directly to control units that have built-in radio
communications, or to radio expanders. Table 1 specifies the number of external radio
siren/strobe units that each type of control unit can support.
The following external radio siren/strobe units are supported:
760ES
External radio sounder.
SND-REXT
External radio siren/strobe unit.
