Please refer to SPC Installation & Configuration Manual for all possible resistor
values and combinations.
Anti-Masking is only reported as "Alarm" type to ARC if area or system is
set.
Wiring the outputs
The expander has 2 on-board, 1A, single-pole changeover relays that can be
assigned to any of the SPC system outputs. These relay outputs can switch a
rated voltage of 30 V DC at 1A (non-inductive load). Fig. 5 shows the wiring of an
active high output.
When the relay is activated, the 'Common' terminal connection (COM) is switched
from the 'Normally Closed' terminal (NC) to the 'Normally Open' terminal (NO).
See Fig. 5: Output Wiring (Active High)
1 Normally Open terminal (NO)
2 Common terminal connection (COM)
3 Normally Closed terminal (NC)
X-BUS addressing
For addressing, reconfiguration, device location, monitoring, editing of names,
X-BUS communication types and failure timer, please refer to SPC Configuration
Manual.
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:
Mount the SPC enclosure in the appropriate position on the wall using all
three fixings (see Fig. 8 item 1).
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.
Remove the enclosure from the wall.
Place the wall plate (Fig 9, item 1) on the wall centring it precisely around
the rectangle previously drawn (Fig. 9, item 2).
Ensure all four flanges on the wall plate are flush with the wall.
Mark the four fixings on the wall plate.
Drill and use suitable screws (max. 4 mm) for the wall substrate.
Fit the wall plate to the wall.
Fitting the back tamper switch:
Insert the tamper switch (Fig. 10 item 2) into the back of the enclosure so
that the plunger faces outwards. (Fig. 10 item 1)
Fit the enclosure back onto the wall using the three fixings previously
removed.
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:
Connect one end of the tamper leads to terminal block CN4 (Fig.1 item
25).
Plug the two connectors at the other ends of the 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
hours) - 77 mA

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)
3 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.
See Fig. 6: Mounted PSU
1 Battery
Ensure that battery flaps are used to hold the battery securely when
mounted in the cabinet.
See Fig. 7: Rotated views
1 Battery
2 Expanders
3 SPC controller or PSU
When installing the SPCP330 (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.
