Equipment Installation

Comark Instruments 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 7 - Bottom View of RF500A Gateway” {Page 25}.
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 Instruments 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 AC 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 ventilation slots on the Gateway 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 the

warranty.
