OVERVIEW
This detector model samples the environmental temperature in the protected area. An alarm condition is raised when the level of temperature
or the thermal variation rate exceeds the alarm threshold.
COMPATIBILITY
This detector is compatible only with wireless systems based on the Sagittarius protocol.
For more specific information concerning compatibility refer to your fire security system supplier.
INSTALLATION - IMPORTANT NOTES
For detector spacing, placement and special applications refer to your specific national standards.
Mount the detector as far as possible from metal objects, metal doors, metal window openings, etc. as well as cable conductors, cables
(especially from computers), otherwise the operating distance may greatly drop. The detector must NOT be installed near electronic devices
and computer equipment that can interfere with its wireless link quality.
This detector must be installed according precisely to the procedures
described in this manual.
Test this detector after installation.
BEFORE INSTALLING THE DETECTOR
1) Power-up the detector (
POWER-UP
).
2) Extract the batteries cover from the back of the detector.
3) Link the detector to the Sagittarius wireless system (
LINKING
).
4) Check the
WIRELESS LINK QUALITY
.
5)
SELECT A GOOD LOCATION FOR THE DETECTOR
.
6) Tag device’s loop and address data (
IDENTIFICATION
).
7) Fix the detector supporting base to the wall (
BASE INSTALLATION
).
LED INDICATORS
Picture 1: provide visual indication for functional conditions and battery levels as indicated in table 1.
POWER-UP
Extract the isolating tab from the back of the detector
(picture 2).
LED indicators signal “Power up”.

LINKING
The system is waiting to achieve a wireless child device (for further information refer to the
translator’s or the Wirelex configuration software’s literature):
1) Move the link switch’s cursor from ON to the opposite side of its run (we will call it
BLANK, since it carries no indication). LED indicators signal “Linking to the system” (picture
3).
Linking is successful when:
a) the translator indicates so (check translator’s literature)
OR
b) the Wirelex software indicates so (check the Wirelex’s literature).
If linking is unsuccessful:
2) Check if evident mistakes were made.
3) Perform the
LINKING RECOVERY
.
LINKING RECOVERY
1) Take out both batteries from their holders
2) Move alternatively the link switch to ON / BLANK five times (picture 3)
3) Move the link switch to ON
4) Reinsert both batteries into their holders, oriented as per polarity marks
5) Perform the
LINKING
procedure
DETECTOR SENSITIVITY SETTINGS
During installation using the Wirelex software it’s possible to set the heat class of the detector (see table 4).
Otherwise if the installation is performed manually through the translator keyboard, default setting will be applied.
WIRELESS LINK QUALITY
It is possible to check wireless link quality between the detector and its linked-to translator or expander in this way:
1) Move the link switch to the ON position.
2) LED indicators will start blinking according to the following table:
3)
NOTE: Ensure the link switch is returned to the "BLANK" (operational) position on completion of testing.
SELECT A GOOD LOCATION FOR THE DETECTOR
Choose for the detector a placement position that:
- compliances with your specific standards
- is reached by a strong wireless signal from its linked-to
translator or expander module
- is not interfered by environmental factors.
IDENTIFICATION
For identification purposes, analogue loop number and device’s
address can be recorded on the plastic tag supplied with the
base (picture 4).
Extract the plastic tag from the bottom of the base, write or label
identification data on it and, finally, insert it in the side slot of the
base.

AB
During all the duration of the
linking phase, the detector must
be only a few inches away from
the translator or expander you
are linking to.
