Auxiliary power supply 12V — Do not use.
Expander is powered through COMM1 on the SPCP355.300 Smart PSU.
29
X-BUS Input power — Do not use.
Expander is powered through COMM1 on the SPCP355.300 Smart PSU.
30
X-BUS Interface — The communications bus connects expanders on the SPC system.
31
Termination Jumper — This jumper is always fitted, by default.
For more information, see
32
PSU 4-pin interface — Connects to COMM1 on the SPCP355.300 Smart PSU (item 12 in image
above), power and data connector, with a straight-through cable.
33
Front tamper switch — Not used. The Front/Back tamper connected to T1 and T2 of the SPCP355.300
Smart PSU is the only tamper required by this installation.
34
JP1 — Front tamper bypass must be fitted.
35
Buzzer — Activated to locate the expander. See
on page 125 for more information.
36
JP6 — Back tamper bypass. Must be fitted.
37
Manual addressing switches — Enable manual setting of the ID of the expander.
38
X-BUS Status LED — Indicates the X-BUS status, when the system is in Full Engineer mode, as
follows:
l
Slow flash (every 1.5 seconds) — X-BUS communications status is OK.
l
Quick flash (every 0.2 seconds) — Indicates one of the following:
– Indicates the last-in-line expander for spur configurations.
– Indicates a communications problem between two expanders. If two adjacent expanders are
flashing quickly, the problem exists between those two expanders.
39
LED — Not used.
40
PSU Status LED.
WARNING: The combined maximum load current drawn from all 12V DC outputs (OP 1–8) plus
COMM1, should not exceed 2.4A. Each individual output, and output A2, should not exceed
300mA. If the device current requires more than 300mA, it is recommended to parallel the outputs.
Adding extra expanders
If adding extra expanders to the G5 housing, you must ensure the front and back tampers are
deactivated by fitting the appropriate jumpers. In a G5 housing, the front and back tamper is handled by
the housing itself and the SPCP355.300 Smart PSU.
7.1.1 Supervised Outputs
The SPCP355.300 Smart PSU supports three, open-drain, logical outputs, which can be supervised for
tamper detection. Output tamper detection is enabled by configuration. Output tamper detection is
enabled by connecting a 4k7 EoL resistor in parallel with the load device, such as an external bell. A
