Introduction to the SPCE650/651/652
The SPCE650/651/652 allows an existing system to be expanded externally
providing additional zone inputs and relay outputs.
The SPCE650/651/652 incorporates the following elements, as shown in Fig. 1.
1. Front tamper switch: The Expander has a front tamper switch with spring.
When the lid is closed the spring closes the switch.
2. Tamper by-pass [J1]: The jumper setting determines the operation of the
tamper. The tamper operation can be overridden by fitting J1. The engineer
must ensure that J1 is removed before leaving site for the system to comply
with standards.
3. Buzzer: The buzzer is activated in order to locate the expander (see SPC
Configuration Manual).
4. Manual addressing switches: The switches allow manual setting of the ID of
each expander in the system.
5. X-BUS Status LED: The LED indicates the status of the X-BUS when the
system is in FULL ENGINEER mode, as shown below:
LED status
Flashes regularly
(once every 1.5 seconds approx.)
Flashes quickly
(once every 0.2 seconds approx.)
6. Outputs: The expander provides 2 programmable outputs for use on the SPC-
series system.
7. Inputs: The expander has 8 on-board zone inputs that can be configured as
intruder alarm zones on the SPC-series system.
8. Auxiliary Power Supply (12 V): These are used to power auxiliary devices to
a maximum of 200 mA.
9. Input Power: The expander requires 12 V DC that can be supplied directly
from the SPC-series controller or from a SPC PSU expander.
10. X-BUS Interface: The communication bus is used to connect expanders
together on the SPC-series system (see section Wiring the X-BUS interface).
11. Termination Jumper: This jumper as a default is always fitted, however,
when wiring for Star configuration this fitting should be removed (see section
Wiring the X-BUS interface).
SPCE651
The SPCE651 enables inertia type sensors to be connected to the zone inputs. It
is important that the inertia sensor is calibrated and the correct pulse count and
gross attack settings are programmed correctly. Refer to the Installation and
Configuration manual for details on configuring analyzed expanders.
SPCE652
Please ensure the back tamper spring has been fitted to the underside of the
expander housing. The spring should be perpendicular to the exit aperture hole
and be firmly connected to the switch plunger on the internal PCB.
Wiring the X-BUS interface
The X-BUS interface provides connection of expanders and keypads to the SPC
controller. The X-BUS can be wired in a number of different configurations
depending on the installation requirements.
NOTE: Maximum system cable length = number of expanders and keypads in the
system x maximum distance for cable type.

Fig. 2 shows the wiring of the X-BUS to an expander/controller and the following
expander/ controller in Spur configuration. Terminals 3A/3B and 4A/4B are only
used for using a branch wiring technique. If using a Spur configuration, the last
expander is not wired back to the controller.

Wiring the outputs
The SPCE650/651/652 has 2 on-board 1-A, 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 (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).

Mounting Expander in SPC Hinged Enclosure
The SPCE650/651/652 may also be installed in a hinged enclosure. This
enclosure can accommodate:
1 battery (17 Ah max.), 1 SPC controller and a 4 I/O expanders (optional)
1 battery (17 Ah max.), 1 PSU expander and 3 I/O expanders (optional)
To access or install an expander:
Open the front cover on the enclosure.
With an appropriate screwdriver loosen (but do not remove) the top two
screws on the mounting bracket.
Gently push the mounting bracket in an upward direction until the screws are
free from contact with the bracket.
Slowly but firmly pull the mounting bracket out until it rotates down and is
secured by the resting pins.
The underside of the mounting bracket and the enclosure provides space for
additional expanders to be installed (secured by 4 mounting pillars).
