Equipment Installation
Comark Limited strongly recommend that RF500 System installation is carried out by a
Comark Installation Engineer or by a Comark Authorised Distributor or Agent.
Gateway Fixing
Mounting of the Gateway is possible using the keyhole screw fixings provided on the rear of
the Gateway itself. However the fixings used are to be determined by the installation engineer
depending on the type of material used in the construction of the area where the Gateway is to
be placed. To avoid accidental disconnection, the DC power cable and cables connecting to
the Relay Outputs should be secured using the cable clamps provided on the Gateway case.
See Figure 2 - Rear view of RF500 Gateway.
Positioning of the Gateway should be in such a way as to limit the risk of liquid being spilt on it
as damage may result.
Transmitter Fixing
Mounting of the transmitters is possible using the mounting bracket provided. The bracket is
fixed using 2 screws and the transmitter then slides into the bracket from the top. With each
transmitter Comark Limited provide two cable ties which, once the transmitter is slid into the
bracket, can be fed through the slots in both bracket and transmitter case to retain it. The door
and DC power cables should be tie-wrapped to the bracket to avoid accidental disconnection.
Mains Wiring
Connections to mains supply for the Gateway and powered Transmitters is via the mains
adaptors supplied and a locally installed socket. Any power requirements for the hardware will
be determined during survey and should be installed by qualified electrician and certified as
safe to use before installation can be started.
Ventilation
At no time should the exhaust from the Gateway fan or the air intake grill be covered or
obstructed. At least 100mm of free space must be provided above and below the Gateway to
ensure that sufficient airflow is maintained through the case to provide adequate cooling.
Failure to do this may result in damage to the Gateway due to overheating and invalidation of
any warranty.
