DESCRIPTION
The PROFESSIONAL PLUS S12VSI-4 is an
Ionisation smoke detector designed for use with
a 12 volt alarm system. The detector is equipped
with a relay, having potential free contacts,
allowing the installer a variety of connection
options. The detector can be configured as either
latching or auto-reset. A test button is provided to
functionally test the relay and outputs of the
detector. An LED illuminates red when in alarm.
INSTALLATION
To
separate the detector from its base, push
together and twist the detector anti-clockwise.
The detector is supplied configured for latching
operation. To change to auto-reset, remove the
small push on link underneath the detector. The
push on link may be "parked" by pushing it back
onto just one of the contact pins. Fix the base to
the ceiling and connect the supply wires to the
terminals marked
+
and- 12v. The alarm circuit
can be connected to the relay connections.
These are as follows:-
C
Common
NO
Normally Open
NC
Normally Closed
The above are shown in the NON ALARM
position.
For most alarm panels using a normally closed
circuit, only the C and NC contacts are required.
A spare terminal is provided in the base for the
installer's' own use, if required. When the wiring
is complete, re-insert the detector into the base,
aligning the LED with the printed triangle inside
the base, push and twist clockwise until the
detector clicks into position.
