When the passive infrared sensor detects motion in its field of view, the transmitter sends a digitally coded wireless signal to the PERS console.\u003c\/p\u003e\n\u003cp\u003eThe digital DXS code format features over a million possible codes. The DXS transmitters are pre-coded at the factory to unique codes, so no field coding is required. The DXS-54 can send three different signals: activity timer reset, low battery, and status.\u003c\/p\u003e\n\u003cp\u003eIn a PERS installation, the motion detector is mounted indoors in a corner or on a wall between six and eight feet high. The sensor will monitor the infrared level in its detection pattern. If the level increases or decreases rapidly (as when a person moves through the area) the transmitter triggers, resetting the activity timer and preventing an inactivity alarm.\u003c\/p\u003e\n\u003cp\u003eThe unit is powered from a 9-Volt alkaline battery. The battery’s life can be up to three years depending on the area’s traffic. When the battery gets low, the test indicator will flash and a low battery signal will be sent to the PERS console when the detector senses motion.\u003c\/p\u003e\n\u003cp\u003eApproximately every hour, the DXS-54 will send a status transmission to the PERS console. The hourly signal updates the PERS console to the transmitter’s condition. By monitoring status transmissions, the PERS console can determine if a transmitter has a low battery or has been removed from the system.\u003c\/p\u003e\n\u003cp\u003eTo conserve battery life, during normal operation, the detector can trigger the transmitter a maximum of once every four minutes.\u003c\/p\u003e\n\u003cp\u003eFor setup and testing, pressing the detector’s TEST button places the unit in walk-test mode for four minutes. The installer can walk in front of the unit while viewing the red test indicator through the detector’s lens to determine the detection area.\u003c\/p\u003e\n\u003cp\u003eIn walk-test, an activity timer reset signal is sent each time the walk-test indicator lights. During normal operation, the detector requires a pulse count of three events in eight seconds before sending an activity timer reset transmission.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eActivity timer reset, supervisory, and low battery transmissions\u003c\/li\u003e\n\u003cli\u003eWalk-test mode\u003c\/li\u003e\n\u003cli\u003eFresnel lens with 24 facets\u003c\/li\u003e\n\u003cli\u003eBattery saver circuitry\u003c\/li\u003e\n\u003cli\u003e9 volt alkaline battery supplied\u003c\/li\u003e\n\u003cli\u003eDXS format\u003c\/li\u003e\n\u003cli\u003eRF frequency: 315 MHz\u003c\/li\u003e\n\u003cli\u003e3.2″ W x 4.4″ H x 1.75″ D\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!----\u003e","brand":"Linear","offers":[{"title":"Default Title","offer_id":48213036663089,"sku":"DXS-54","price":1145.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0858\/5314\/3345\/files\/LInear_DXS-54_742a1696-cb78-45e4-8c42-d06ab032a8f7.jpg?v=1720569689","url":"https:\/\/ameratec.com.hk\/products\/linear-dxs-54","provider":"Ameratec","version":"1.0","type":"link"}
