Gateway Board Connection Options
Installation
4.3.1 Connecting to a Fire Alarm Panel
To know about supported panel variants, their connection options, and commissioning
procedure, refer to the
“Connecting to the Panels” on page 105
4.3.2 Installing a Cellular Module
Cellular modules enable value-added alarm transmission services from a protected
premises to the CLSS-connected site and to a central receiving station. If required, you
can plug in the device onto the gateway board.
Compatibility Requirements
To ensure proper operation, these cellular module shall be compatible with the CLSS
Gateway.
To know more about the supported devices, refer to
“Compatible Cellular Modules” on
.
Before Installing a Cellular Module
•
If installing on an existing operational gateway, inform the operator and local authority
that the gateway will be temporarily out of service.
•
Disconnect power to the gateway.
Precautions for Service Quality
•
Carefully select the installation location of the CLSS Gateway.
•
Do not mount the gateway on or near metal objects. This includes steel cabinets,
metal walls, steel beams, steel roofs or roofing girders, foil backed insulated walls, and
duct works.
•
During the installation, periodically monitor the signal quality via the CLSS App to
predict QoS (Quality of Service) of the LTE radio over time.
If the installation location does not offer good QoS, try the following options:
1. Move the gateway to achieve the best QoS. Typically, moving it to a higher
placement offers the best QoS.
2. Use an optional antenna external aerial connection. Antenna must be located in
the same room as the CLSS Gateway enclosure. Refer to the
for details.
To Install a Cellular Module
The installation involves plugging the cellular module onto the gateway board, and
securing the mounted device with a retention strap. The strap will compress the RF
ground system between the cellular modules and the gateway board assembly.
1. Switch OFF the gateway.
2. Punch out the appropriate knockouts on the enclosure for the aerials (see
).

NOTE:
When the gateway is communicating to a central station through cellular
connection, it uses the primary Ethernet connection for
CLSS Site Manager
communications.
