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 then
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.

A
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:
With an appropriate screwdriver, loosen (but do
not remove) the top two securing screws on the
mounting bracket.
Gently push the mounting bracket in an upward
direction until the screws are free from contact
with the bracket.
