Jointing
One of the advantages of the Alarmline II Digital Sensor Cable is that damaged
sections of cable can be cut out and replaced without having to replace the entire
cable run. When a cable has been activated or has been damaged, the section of
the cable can be cut away and a new section of cable can be jointed into the
existing cable run.
Joint the cable using suitable junction boxes and ensure that it is jointed correctly
to prevent any problems from bad connections, etc.
Connecting sensor cable to a monitored input
Caution: Before connecting the sensor cable to any control equipment, consult
the technical documentation provided by the equipment manufacturer.
The sensor cable can be connected directly to any control equipment with a
monitored input which can detect the operation of a switch changeover. The most
common types of system would be either a conventional fire alarm control panel
or an addressable fire alarm control panel.
For a conventional fire alarm panel, the sensor cable can be connected directly
to a detection zone input. Any detection zone used would be specific to the
Alarmline II Digital Sensor Cable with no other detection devices attached to the
zone.
For an addressable fire alarm panel, the sensor cable can be connected to the
control panel:
• Via the control panel monitored inputs (if available), or
• As a device on the addressable loop using a suitable loop interface (for
example, a Zone Monitor Unit or Switch Monitor Unit)
Regardless of whether the sensor cable is fitted to a conventional detection zone
or a loop interface on an addressable fire alarm control panel, the configuration is
the same (see Figure 3 on page 15).
