Base
The base has terminals for external cables to allow it
to be electrically connected to the panel loop circuit
and to the monitored input or output circuit. Any
S-Quad device can be plugged into a S-Quad base.
Base with IP21 Plate
The 'Base' requires a 'IP21 plate' to prevent water
damage from dripping water from the ceiling.
&
The 'Base' with 'IP21 Plate' must
be used with Visual Alarm and Sounder
Alarm S-Quad devices to meet Standards.
Failure to use 'Base' with 'IP21 Plate' will
contravene the requirements of the
Standards.
Base labels
An optional label (Part No: 805576) can be fitted to
the base. The label can be marked up with device
location information.
Lock
Refer to the instructions supplied with the Base for
instructions on how to lock the Sensor to Base.
Indicators
The S-Quad has a red LED that gives an indication in
the event of a fire. The LED can be configured to flash
periodically, as an 'in operation' confirmation, this
indication is given system-wide at all S-Quads. The
S-Quad with a CO sensor also has a blue LED to
indicate when a fire signal senses the presence
of CO.
Dust Cover
A dust cover is supplied with the S-Quad, to prevent
dust from building work contaminating the sensor.
The cover is removed prior to the commissioning of
the fire alarm system.
Monitoring
Under normal conditions the S-Quad devices are
monitored regularly and the data is used to create a
background performance record. When there is a
potential event, the S-Quad device will flag the control
panel for attention. The control panel will take further
readings from the device and compare all the
measurements with patterns and rules to determine if
it is a fire event.
