INSTALLATION AND CONNECTION
SITING OF THE ANTENNA
The supplied 4G antenna is an external item that should be installed in the most suitable position so that
1. As high as possible and obtaining the maximum signal strength, checked by a 4G Analyser
(please see detailed instructions provided with the Analyser).
2. Further than 200mm from a human body.
3. Minimising risks of vandalism.
CABLE ENTRY AND EXIT
Ensure that Antenna, Power and other Cable Leads are looped before entering the back of the Unit to minimise water
ingress along the cables.
The cable entry hole in the back of the back box is a threaded M20x1.5mm and is suitable for metal/plastic electrical
conduit ttings.
The unit is supplied with a 20mm gland to allow wires to pass in and out of the back box where cables may have to travel
a short distance to the control unit – we suggest once wiring is complete this gland is lled with electronic grade silicone
sealant. Examples of this type of silicone are:
1. American Sealants Inc 388
2. ACC Silicones AS1745G
3. Dow Corning 3145
There are many other equivalent makes.
DO NOT USE silicone’s with acetic acid (vinegar smell/bath sealant) as the fumes given off in the conned space
of the Backbox can corrode delicate electronic parts.
If using metal/plastic conduit screwed into the box of the Intercom unit the supplied gland may be discarded.
POWER CONNECTION AND DISCONNECTION OF THE OPTIMUS RANGE
The Intercom unit is dened as Pluggable Equipment Type B tted with a 3A fuse.
Power to the unit must be provided through connection to a locally accessible switched 13A Mains UK standard socket
outlet.
The supplied Power Supply Unit is tted with 1.5mtr lead and terminated with a UK standard 13A plug tted with a
3A fuse.
Should it be necessary to disconnect power to the Intercom Unit, then this is done by switching off power at the mains
switched socket that supplies the Unit.
