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/stobe unit.
Plug-by outputs (depending on the control unit), used for communicating alarms to
an Alarms Receiving Centre (ARC).
Control unit USB and Ethernet ports
The control unit includes both USB and Ethernet ports.
You can use the USB port to:
Program the control unit from a PC using the Downloader software (see page 23).
Apply firmware updates to the control unit using the i-on Update Utility software. For
European versions, the utility also allows alternate language text files for the keypad
display to be installed.
Connecting the control unit to a network through the Ethernet port allows you to:
Configure the control unit and update firmware using the web interface (see page
Communicate alarm information to an alarms-receiving centre using SIA-IP.
Configure the control unit using the Downloader software (see page 23).
Keep the time at the control unit automatically updated using an SNTP server
located on the internet.
Store images from network cameras (on the SD card).
Send emails automatically when events occur.
Sounders
The i-on control units support external wired siren/strobe units, and internal radio
sounders. Table 1 specifies the number of sounders of each type that each control unit
supports.
External wired sirens/strobes
The control units have 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:
SND-WEXT-G2
Wired Grade 2 Siren.
SND-WEXT-G3
Wired Grade 3 Siren.
Third-party units
With compatible connections.
