SPC-E PHOTOELECTRIC BEAM DETECTOR
MOUNTING GUIDELINES
When installing the SPC-E Beam Detectors, it is important that the following guidelines are adhered to:
Do not mount in locations that are exposed to
extremely high temperatures or water vapour.
Do not mount SPC-E within 300mm of any
obstruction.
Do not mount where the distance between the
Emitter and Receiver is less than 5 metres or greater
than 100 metres.
Make sure the surface that the SPC-E units are to
be mounted on is rigid (ideally part of the building
structure) to avoid any possibility of movement.
When fixing the SPC-E allow enough space to gain
access to the sight hole for aligning purposes (this is
located on the top right hand side of the Receiver
unit, when viewed from the front).
List of Parts
The SPC-E Beam Detector kit consists of three separate parts:
SPC-E Receiver and Emitter.
2 x four pronged Mounting Plates.
Test Filters (25%, 50% and 60%).
Mounting the SPC-E Beam Detectors
The SPC-E Beam Detectors are designed to mount vertically onto the four pronged mounting brackets supplied. These
brackets should be fixed securely to the wall and directly opposite each other, they must also be mounted in the same
horizontal plane.
There are several wiring methods available for the SPC-E, all of which are further explained in our Application Note
AP097 available from our website. The most common wiring method is shown below. In all methods, cables should be
brought through the top of the back box, and terminated into the appropriate connector blocks. The SPC-E Beam
Detectors require the use of an auxiliary 24Vd.c. Power Supply Unit (not supplied). The Power Supply and field wiring
should be terminated into the front of the SPC-E. Refer to Fig.1 if the panel requires a short-circuit to produce a fire
condition. If the panel requires a fire resistor refer to Fig 2.

Note: The Emitter can be powered directly from a local 24Vd.c. power supply, the Conventional zone or an ESP loop.
