Zones/Outputs Configuration
If a I/O for a specific
door is configured as ‘Zones/Outputs’, the inputs can be used
as normal wired zones except that their zone numbers will be floating (not tied to
the X-BUS ID, similar to wireless zone numbers) and the outputs are used as
normal.
Please refer to
SPC Configuration Manual
for all possible EOL resistor values and
combinations in addition to configurable zone types.
Anti-
Masking is only reported as ‘Alarm’ type to ARC if area or system is
set.
Wiring the outputs
The expander has 2 relays. These are single-pole changeover, rated at 30 V DC /
1 A resistive load.
If the I/O for a specific door is configured as a ‘Door’, the relay
can be used for opening a door lock. Otherwise it will be configured for
‘Zones/Outputs’ and the relay can be assigned to any of the SPC system outputs.
Fig. 5 shows the wiring of a normally closed output used with some types of door
locks.
See Fig. 5: Wiring the door lock.
X-BUS addressing
For addressing, reconfiguration, device location, monitoring, editing of names,
X-BUS communication types and failure timer, please refer to

Back tamper switch installation
The back tamper switch (Fig.1 item 26) is required for SSF Larmklass 2 and EN
Alarm Grade 3.
The back tamper switch is delivered with SPCP333 or is available as an optional
extra (SPCY130).
Mounting the wall fixing plate:
1
Mount the SPC enclosure in the appropriate position on the wall using all three
fixings (see Fig. 8 item 1).
2
Draw a line around the inside of the back tamper cutout (see Fig. 8 item 2) to
provide a guide for the wall plate on the fixing wall.
3
Remove the enclosure from the wall.
4
Place the wall plate (Fig 9, item 1) on the wall centring it precisely around the
rectangle previously drawn (Fig. 9, item 2).
5
Ensure all four flanges on the wall plate are flush with the wall.
6
Mark the four fixings on the wall plate.
7
Drill and use suitable screws (max. 4 mm) for the wall substrate.
8
Fit the wall plate to the wall.
Fitting the back tamper switch
1
Insert the tamper switch (Fig. 10 item 2) into the back of the enclosure so that
the plunger faces outwards. (Fig. 10 item 1)
2
Fit the enclosure back onto the wall using the three fixings removed previously.
3
Visually check to ensure there is a flush finish between the wall plate and the
enclosure metalwork.
WARNING:
If the wall-fixing plate is not accurately aligned, the enclosure will
not sit properly on its fixings.
Wiring the back tamper switch
1
Connect one end of the tamper leads to terminal block CN4 (Fig.1 item 27).
Plug the two connectors at the end of the tamper leads onto the COM (common)
and NO (normally open) spade connectors on the back tamper switch.

Appendix C: Choosing the stand-by battery
The table below shows the maximum total current (in mA) that can be drawn from
all outputs for EN compliance. Note that other limits apply, for example, the
maximum current that can be drawn from each of outputs 1 and 2 is 750 mA.
Available current in mA = 1000 * (0.85 * battery capacity in Ah) / (standby time in

Appendix D: Fitting additional expanders in the SPC
hinged enclosure
The enclosure can accommodate:
1 x Battery (17 Ah max.)
1 x PSU Expander (SPCP330)
x I/O Expanders (optional)
To access the expanders and the PSU, open the front lid to view the hinged
mounting bracket. The boards are secured to the hinged mounting bracket by four
mounting pillars.
To access or install a PSU in this enclosure:
1
With an appropriate screwdriver, loosen (but do not remove) the top two
securing screws on the mounting bracket.
2
Gently push the mounting bracket in an upward direction until the screws are
free from contact with the bracket.
3
Slowly but firmly pull the mounting bracket out until it rotates down and is
secured by the resting pins
4
The underside of the mounting bracket and the enclosure provides space for
additional expanders to be installed (secured by four mounting pillars).
The PSU is secured to the front of the enclosure by mounting pillars.

SPC controller or PSU
When installing the SPCP430 (PSU and Expander), ensure that the 4-
pin cable is securely attached to the connector on the expander and to
the PSU beneath.
Appendix E: Mounting Fixtures
Screws with a 4-5 mm shank, a minimum head diameter of 8 mm and a length of
at least 40 mm are recommended for mounting the cabinet.
Additional expansion plugs or fixings may be required depending on the
construction of the mounting wall.
Please refer to the SPC Configuration manual for further information on mounting
the cabinets.
