Wireless devices Chapter 1 Introduction The VEGA-SAGITTARIUS integrated wireless system is the result of an accurate analysis of in-depth research into issues relating to difficult applications (for example, notable buildings and places of architectural importance) and the high cost of redecoration work after installation. It is also a truism that wireless systems are unable to effectively replace traditional hard-wired systems, as their reduced- performance (attributable to the deployment of conventional detectors which are incapable of transmitting fault signals) tends to keep maintenance, and consequently...
Sagittarius Chapter 2 System architecture The wireless section of the fire-alarm system comprises a VW2W interface module that is connected to, and powered by, the loop. The interface communicates with the system it serves through the communication protocol used by the control panel, and receives signals from SAGITTARIUS series devices over the Virtual Wire ®...
Wireless devices Communication mode The wireless devices communicate with the translator and wireless range extenders using 868Mhz frequency band with GFSK modulation. The data transmission system comprises 7 channels. The data transmission channel is selected in accordance with signal quality. Data transmission is bi-directional with feedback (acknowledge).
Sagittarius Chapter 3 System devices The following table describes the devices which can be used with the system. Device Type Description VW2W Protocol translator Uses wired communication technology to notify the control panel (VEGA protocol) and wireless communication technology to communicate with its devices SGWE Expander...
Wireless devices Chapter 4 VW2W protocol translator The VW2W Protocol translator is connected to, and powered by the loop. It communicates with the control panel via VEGA communication protocol. Connecting the translator to the detection line Using terminal 1 (vedi Figura 1), connect the translator to the detection line. Be sure to observe proper polarity.
Sagittarius Enrolling locally Connect the translator to the detection line, or to a 24Vdc (15Vdc – 40Vdc) or to the ARGUS ‘line driver’: 1. On power-up, various symbols appear on the display for approximately 1 second 2. The display then clears (Status 0) Using the Ú: keys, you can scroll the various function statuses: •...
Wireless devices RF — Enrolling wireless devices on the Loop via Translator (Status 0-2) If you select RF mode, the system will enroll the wireless section of the translator and the wireless communication device type will be assigned to the translator connected to the detection line.
Sagittarius • Communication mode: 1. Press the Ú key: display will show “ ” (Status 0-2-1-2) 2. Press the ;key: display will show the number of the current communication channel (Status 0-2-1-2-1). 3. Using the Ú: keys, select the required communication channel. 4.
Wireless devices 2. Press the ; key. You will access the detector enrolment phase. The display will show “ ” (Status 0-2-2-1). LINK 3. Press the ; key. The display will show “ ‘ II ” and the radio wave symbol “ ’...
Sagittarius LINK 3. Press the ; key. The display will show “ ‘ II ” and the radio wave symbol “ ’ ”. Enrolling an input module 1. Take the modulesyou intend to enrol on the translator. Check that the secondary battery is present (the battery must be properly located it in its housing).
Wireless devices 2. Connect the output module power supply wires to the respective terminals; be sure to observe proper polarity. Power on the module. The LED will blink red 4 times and then will go OFF: this indicates that the output module has been identified by the translator.
Sagittarius 2. Press the ; key to enter in the LIST phase. The display will show “ LISt ” (Status 0-3-1) 3. Press the Ú: keys to view the type of protocol the translator uses to communicate with the detection line. 4.
Wireless devices Chapter 5 SG100, SG200, SG350 analogue addressable wireless detectors The SG-XXX series smoke, heat and multi-criteria detectors from the SAGITTARIUS range communicate with the panel via a VW2W wireless translator. The figure below shows the wireless detector and his base: Figure 2 - SG-XXX detector Tamper switch Detector unit...

Sagittarius SG100 The SG100 optical smoke detector complies to EN54-7. The double dust trap ensures high protection against dust contamination and keeps maintenance to a minimum. Variable threshold sensitivity increases the capability of true fire detection and significantly reduces the false alarm rate. The detector will trigger an alarm if the quantity of smoke in the protected ambient exceeds the alarm threshold.
Wireless devices • heat analysis channel fault • low battery Test The periodic Self Test feature ensures full functionality at all times. Any faults found during the periodic Self Test will be signalled on the detector LED and reported to the panel. The in-built magnet test facility allows easy verification of proper performance of the installed detector system.The magnet test simulates smoke in the detection chamber and therefore tests the electronic circuits of the detector and signal transmission to the control panel.
Sagittarius channel fault; contamination; low battery) will be signalled on the LED and reported to the panel. Technical Specifications Detection devices have the same technical specifications as all other devices on the detection line. • Cover: with regard to cover in the area protected by detection devices, refer to acknowledged national or international application standards and fire codes (for Italy refer to EN9795).
Sagittarius Chapter 6 SGCP100 manual resettable callpoint The resettable callpoint is housed in a plastic enclosure with a plexiglass operating element. The easy turn-key reset method makes the unit ready for immediate re- use after reset operations. On activation the LED (controlled by the control panel) goes On (red) and a yellow- striped flag appears.
Wireless devices Visual signalling (LED) The centrally positioned bicolour LED (red/green) provides the following visual indication of the device and battery status: Device status Green LED Red LED Normal Primary battery down Intermittent blinks 0.1 sec on - 5 sec off Secondary battery down Intermittent blinks 0.1 sec on - 5 sec off...
Sagittarius Chapter 7 SGMI100 input module The SGMI100 supervised alarm input module monitors the status of external devices (gas detectors, etc.) for interface with the fire detection systems. The supervised input is configured with an End-Of-Line resistor for line supervision. Visual signalling (LED) The bicolour LED (red/green) provides the following visual indication of the alarm or fault status.
