Argus Security SG100 - Wireless Optical Smoke Detector Manual

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.

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.

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).

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.

5. Put on the battery cover.

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.

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).
   

WIRELESS DETECTOR ANTI-TAMPER BLOCK AND REMOVAL

The base for the wireless optical smoke detector has a special anti-tamper device block. To lock the sensing device onto the base, cut off the small plastic lug on the plastic blocking grip on the detector base (Picture 6).

To remove the blocked detector from the base, insert a tool, like a small screwdriver, into the hole and remove the detector (Picture 7).

TESTING

The wireless optical smoke detector has been designed to permit a magnetic functional test. When the test is performed with an appropriate magnet, a fire alarm message is sent to the control panel via translator / expander.
To perform the magnetic test put and hold the magnet near the surface of the indicated area (Picture 8). The detector must enter into alarm condition, activate the central LED indicator (blink red as per Table 1) and transmit the alarm message to the control panel.
The detector must be reset by the specific command on the control panel (see the RESET paragraph). All detectors must be tested after installation and, successively, on a periodic basis.

RESET

To reset the detector from alarm or fault condition it is necessary to send the reset command from the control panel.

TAMPER DETECTION FEATURE

The wireless optical smoke detector is provided with a tamper switch and, in case of removal of the detector from its base, it sends a tamper detection message to the control panel (Picture 9).

MAINTENANCE

1. Before starting any maintenance work, isolate and disable the system, in order to avoid accidental and unwanted alarm conditions.
2. Remove the detector from its mounting base to allow inspection and servicing at ground level and in good light.
   Inspect the smoke entry ports around the sensor and use a small, soft bristle brush to dislodge any obvious contaminants such as insects, spider webs, hairs, etc.
3. Use a small vacuum tube or dry, clean, compressed air to suck up or blow any remaining small particles away from the smoke entry screen area.
4. Wipe the exterior housing of the detector with a clean, damp, lint-free cloth to remove any surface film that can later attract airborne contaminants.
5. After all detectors have been inspected and serviced, reinstall them in their mounting bases, re-apply power to the system and check correct operation as described under the TESTING paragraph.

FAULT SELF-TEST

The wireless optical smoke detector periodically performs a self-test and, if a fault condition is detected, a fault message is sent to the control panel via translator / expander.
The fault condition is locally signaled by the visual LED indicator located at the center of the detector (see Table 1). A fault condition is determined by:

1. Fault on the optical analysis path (chamber, electronic circuit, etc).
2. High level of contamination inside the optical chamber.
3. Low batteries level.
