Argus Security SG100 Manual

SG100
WIRELESS OPTICAL SMOKE DETECTOR
GENERAL DESCRIPTION
The wireless optical smoke detector continuously samples the air in the protected area to provide the earliest warning of fire and yet
offers a high level of false alarm rejection. An alarm condition is determined when the level of smoke inside the optical chamber
exceeds the alarm threshold; consequently an alarm message is sent to the control panel through its wire to wireless translator
module and, eventually, one or more wireless expander modules.
The advanced design of the smoke inlet of the optical chamber guarantees a very high rejection to the introduction of dust, effectively
increasing the time between maintenance periods.
Communication between the detector and the translator / expander modules is wireless, via the „Sagittarius‟ bidirectional protocol.
PARTS OF THE PRODUCT
DETECTOR'S VISUAL LED INDICATOR
The wireless optical smoke detector is equipped with a bicolour LED
(red / green) that provides visual indication for functional conditions and
battery levels as indicated in table 1.
DEVICE'S POWER SUPPLY AND LINKING
The linking operation permits the configuration of the wireless optical
smoke detector on the translator module.
The linking operation described below does not change if made directly
from the translator module or from the PC configuration program;
please, refer also to the "Guide to wireless system installation" and
similar documentation.
.
1) Verify that the secondary battery is present; if not, insert the battery
into its housing with the positive pole facing up (Picture 2).
2) Move the switch to position ON (Picture 3).
3) Insert the main battery (Picture 4).
Ensure that battery polarity is correct.
The visual LED indicator switches green once, then four times red
(programming mode) and will, successively, turn off. This
indicates that the detector is ready to be linked to the translator
module.
4) Move the switch in position 1 to trigger the communication between
the detector and the translator.
The green LED switches on once, then it blinks many times
(operating mode), successively the red LED blinks many times
(self-adjustment mode) and, finally, after alternating green-red for one second, the indicator turns off: this indicates that
the linking procedure has been performed correctly and the detector has programmed itself .

Table 1
The detector is linked and all the parameters (address, system code etc.) necessary to work correctly are stored.
If the LED remains switched on the red light it means that the linking operation failed. In this case remove the main
battery, switch alternatively the ON / 1 switch a few times in order to discharge the internal capacitor and then start again
from point 2).
IMPORTANT NOTE! Programming is considered to be completed successfully only if there is an indication of programming
success on the detector and on the translator or on the window of the PC configuration program.

COMMUNICATION QUALITY ASSESSMENT

It is possible to assess the wireless communication quality of the sensor by using a testing feature built in the device.
After a successful linking operation, by moving the Link-Programming switch on the ON position, the sensor‟s indicator will start
blinking according to table 2.
Always remember to reposition the switch to 1 after the assessment operation: device will NOT work operatively while the
switch is on the ON position.
Communication quality
No connection
Link margin is less than 10 dB
Robust communication with link margin from 10 dB to 20 dB
Robust communication with link margin over 20 dB

DETECTOR PLACEMENT

For specific information regarding detector spacing, placement and special applications refer to your specific national standards.
It is strongly advised to mount the device 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 device should not be
installed near electronic devices and computer equipment that can interfere with the reception quality.
1) Select the position of the detector before installing and fixing its supporting base. Verify, from that position, that the
communication between the detector and the translator or the expander is correctly established and working (see the
COMMUNICATION QUALITY ASSESSMENT paragraph).
2) Install and fix the base, in the selected position, with the screws provided (Picture 5 and Picture 6).
3) Insert the detector onto the base (Picture 5).
