SPECIFICATIONS
Note:
Housing manufacturer installation & maintenance instructions can be
found within the housing and should be observed prior to fixing.
ADDITIONAL FEATURES
The equipment utilises pulse modulation.
For high security and avoidance of cross talk between beam sets, the
system can be synchronised by means of an ‘asynchronous’ connection.
For lower security and avoidance of cross talk between beam sets, the
system can be synchronised by means of a ‘synchronous’ connection.
The GS100 circuitry incorporates ‘Sync. Line’ monitoring, providing a change
of relay state (alarm O/P) at the receiver (RX), if the synchronisation cable is
maliciously or accidentally cut, or short circuited.
The product is guaranteed against faulty workmanship for a period of 2 years
from date of despatch.
Our progressive design policy reserves us the right to modify our
products, data and specification, without prior notice.
The infra-red beam is designed as a detection device only and its
output used for connection to an alarm control / monitoring panel. As
such we will not accept responsibility for any theft / damage.
INSTALLATION GUIDANCE NOTES
Please additionally refer to any supporting instructions that may be provided
by the housing manufacturer and may be present within the TX or RX
housing.
Using the M6 mounting holes at the rear of both TX and RX housings, the
units should be mounted on a rigid, vibration free flat surface. Depending
upon the structure being fixed to, it may be necessary to employ some form
of mounting plate, as the housings must not in any instances be drilled.
The transmitter (TX) & receiver (RX) unit should be mounted so as to face
each other squarely, and at the same height, assuming that the ground is
level.
The optical heads of the TX & RX can be adjusted (+/- 15deg. approx.),
however the housing aperture restricts movement and should be used as
a means of overcoming unavoidable inaccuracies that may occur during
installation.
Further adjustment is catered for in the TX & RX mounting plates. Two
sets of mounting holes are provided (one set above the other), allowing the
electronics and associated optics positions within the housings to be shifted
in the vertical plane.
Where greater angles are required, then this should be dealt with using
suitable adjustable mounting plates.
Cable type, mechanical protection, and entry glands should be provided by
others and suitable for the type of installation.
When choosing the appropriate cable for the installation, consideration
needs to be paid to the TX & RX terminal cable size (refer to tech. spec.)
and in particular to the size of conductor used for the 12V DC supply voltage
over the length of the cable run (to avoid voltage drop).
Where it is decided to use optional heater elements to combat condensation
build up on the glass apertures (external exposed locations), then it is good
practice to use a separate pair of conductors for the supply voltage to the
heater terminal connections.
The TX & RX units should be connected in accordance with the wiring
diagrams provided, with connection made to the heaters and tamper
switches where fitted.
A separate terminal block is provided on the underside of each heater
module, and requires a 12V DC supply voltage for element operation
(refer to tech. spec. for current of each heater). For ease of installation,
the termination block is removable (pull downward off of board connection
mounting pins). Note: cable connections are to the outer two terminals only,
the centre one not being used.
