DSC WS4926 Installation and Operating Instructions (English French)

WS4926 Series Wireless Smoke Detector and Operating Instructions this instruction sheet thoroughly before installation and use of the WS4926 Wireless Smoke Detector WS4926 is a wireless photoelectric smoke detector with an inter piezoelectric alarm Three versions are available US UL Canadian and European EU Button Sounder removal of the detector from the mounting plate initiates a transmission The tamper condition is restored after the detector mounted on the plate Transmissions supervisory message is transmitted at 64 minute intervals to the panel If the signal is not received the control panel determines the detector is missing detector transmits the following Alarm Alarm Restore smoke alarm Transmitted at time of Tamper Tamper Restore tamper switch activated 10 second delay on restore before transmission Low Battery battery voltage falls below threshold Battery volt is tested transmitted at the time of a supervisory or other Trouble detector fault or sensor compensation limit reached are transmitted at the time of occurrence one trouble per interval WS4926 is powered by two 3VDC lithium batteries see Specifica section NOT use batteries other than those listed low battery threshold is set so the batteries will provide not less 14 days of operation at which point the detector will send a battery signal If the battery is still 7 days after falling the low battery threshold the sounder will once every seconds until battery failure During the first 7 days after low bat detection non chirp period if the detector is tested or goes into the sounder will once the test or alarm is restored and until battery failure batteries can be purchased from the distributor the company hardware stores or supermarkets etc Instructions WS4926 Series wireless smoke detector shall be installed and within an environment that provides the pollution degree max 2 over voltages category II NON HAZARDOUS LOCATIONS only The equipment is designed to be installed by SERVICE only SERVICE PERSON is defined as a person having the technical training and experience necessary to be aware hazards to which that person may be exposed in performing a task of measures to minimize the risks to that person or other per Smoke Detector Placement smooth ceilings detectors may be spaced 9.1m 30 feet apart a guide Other spacing may be required depending on ceiling air movement the presence of joists uninsulated ceilings Consult National Fire Alarm Code NFPA 72 Chapter 11 CAN or other appropriate national standards for installa recommendations Do NOT locate smoke detectors at the top of peaked or gabled ceil the dead air space in these locations may prevent the unit from smoke Avoid areas with turbulent air flow such as near fans or windows Rapid air movement around the detector prevent smoke from entering the unit Do NOT locate detectors in areas of high humidity Do NOT locate detectors in areas where the temperature rises 38 100 or falls below 5 41 Smoke detectors in accordance with NFPA 72 Chapter 11 detectors shall be installed outside of each sleeping area in immediate vicinity of the bedrooms and on each additional story the family living unit including basements and excluding crawl and unfinished attics In new construction a smoke detector shall be installed in each sleeping room Marks every 7 to 8 seconds the unit tests for a smoke alarm During this sequence the unit also performs self diagnos and checks for tampers and faults During normal operation the will flash every 50 seconds and the sounder will not sound Alarm smoke detector will go into alarm when the signal level exceeds threshold and automatically restore when the signal level below the alarm threshold During an alarm the LED will 1 second and the sounder will sound the evacuation temporal UL ULC EU smoke detector has a preset warning threshold at 75 of the threshold If the signal level stays above this threshold but the alarm threshold for more than 120 seconds the detector go into the state If the signal level falls below the early threshold the detector will restore to its normal automatically If the signal level rises above the alarm threshold detector will go into alarm The LED will flash and the sounder will every 50 seconds when in the warning state This feature is intended to provide a warning if the environ is persistently close to the alarm threshold and provide more to investigate and either escape or correct the situation Drift Compensation detector automatically compensates for long term environmen induced changes to maintain a constant smoke sensitivity When drift compensation has reached its high or low limit of adjust the detector will go into the trouble state Silencing ULC models only smoke alarm is provided with an alarm silencing feature When sensor is in alarm by pressing the Test Silence Reset button it will the local annunciation of the alarm and transmit an alarm event to the control panel The LED will flash every 8 seconds up to 8 minutes to indicate the alarm has been silenced The LED will stop when the unit returns to normal operation The silence feature has a fixed time setting that desensitizes the alarm for 8 minutes Alarm silencing does not disable the alarm but rather reduces its smoke sensitivity Following the period the smoke alarm restores automatically to its normal If smoke around the unit is dense enough to suggest a dangerous situation it will stay in alarm Mount Smoke Detector Backplate backplate to the the screws pro The dust protects when not in ser before Holes CR123A CR123A Install Batteries batteries are not install batter in the sequence Use only or Duracell batteries are installed the tab activate Mounting Detector Installation the detector on to base plate using the and base plate marks Press the gently in place rotating the detector until the detector into place Remove side tab from the lock tab to lock in place Removal tab with a small slotted screwdriver Rotate detector coun until the alignment marks line up Remove detector Compensation Reset or replacement of the smoke sensor chamber changes the signal noise of the detector this requires the drift com be reset Compensation trouble is one of the faults indi when the LED indicator is OFF while the sounder is chirping Remove batteries then short the detector battery contacts for 5 to power down unit batteries to power up unit while pressing the test but tamper switch must not be pressed LED will flash when 5 seconds has elapsed Release the test within 2 seconds of the LED flash LED will flash every 2 seconds for 1 minute During this the detector must be mounted an additional 2 minutes for the detector to make back level checks the detector to verify normal operation Test Unit The central monitoring station if used should be notified to the test being generated This will prevent a false alarm and unnecessary response from the central monitoring station test by pressing the test button for 5 seconds minimum activation is indicated by the flashing LED the sounder and of the alarm signal to the control panel The detector to normal when the test button is released Allow a minimum of 20 seconds after power up and after alarm or tamper restore activations Do not use test button smoke is present If the detector is in one of the following states when a test is it will not enter an alarm state Tamper detector not installed on mounting plate Compensation Trouble Other internal faults that could prevent a smoke or heat alarm Smoke sensitivity of installed detectors can be measured removal or an alarm being generated using the FSD 100 Detector Test Meter test the unit using the FSD 100 set the test meter up to read as per the instructions supplied Depress the test button on smoke detector for 1 second
