The EXP-PSU is a remote power supply intended for use in
wired/wirefree alarm systems controlled by the i-onEX range of control units.
This product offers the following benefits:
Powerful 3A supply. Independently charge and monitor one
or two batteries. Mix and match batteries to meet system standby requirements:
Maximum 2 x 17Ah.
Added flexibility for i-onEX installations. 10 zones
onboard. 16 plug-by outputs for local connection of a communications device.
Four transistorised outputs.
Easy to install and configure. Mains plus simple bus
in/out connection. Semi-Auto addressing for speed and device numbering
integrity. “Self installs” once addressed, go straight to adding detection
zones.
Simple to service and support. Unique audible bus device
locator. Power monitoring through keypads or web
interface.
The power supply comprises a steel case containing a pcb
(printed circuit board) and space for up to two 17Ah backup batteries. The unit
can monitor and charge each battery independently and an installer can use
combinations of batteries to meet their standby
requirements.
The pcb also provides connectors for four transistorised
outputs, 16 plug-by communicator outputs (mirroring those on the control unit),
and up to 10 FSL (Fully Supervised Loop) or five CC (Closed Circuit)
zones.
The EXP-PSU connects to the i-on control unit and the
rest of the alarm system by means of the system bus, providing monitoring
messages to the control unit over the bus. These messages include Remote PSU
Fault, Remote AC Fail, Remote Battery Fail, and Remote Low Output
Voltage.
During installation the EXP-PSU uses the same
semi-automatic addressing procedure as other i-on expanders. The unit also
provides an audible locator and allows power monitoring through the system
keypads or the web-browser within the i-on control
unit.
The EXP-PSU is designed and approved to be used as part of a Security Grade 2 or 3 system.
