Standard Motion Sensor Module DC Input Motion Sensor Module 5V/12V DC Input Microwave Motion Sensor - Standard Version HNS102 5.8GHz C-band microwave, tri-level dimming function. Input voltage: 12V DC (5V & 24V DC version available on request). Input current: 25mA. Features 5.8GHz C-band microwave, tri-level dimming function. Input voltage: 12V DC (5V & 24V DC version available on request). Input current: �?� 25mA. 0~10V DC dimming output signal. Super compact, flexible to be integrated into any suitable fixtures. Dual-PD technology, real Daylight monitoring function for built-in application. 8 pin DIP switch setting, multiple options to meet different customer demands.  Detection range up to 12m in diameter. Mounting height: 3~6m. Operation temperature: -20�??~ +70�?? . RoHS compliant. Detection range Detection range can be reduced by selecting the combination on the DIP switches to fit precisely each application. Hold-time Hold-time means the time period to keep the lamp on 100% after motion detected. *when hold-time set as 3s# sensor enters into test mode, this test mode is mainly for users to choose the desired detection range. In this mode, the daylight sensor is disabled, when there is no motion, fixture keeps off, when there is motion detected, fixture keeps a cycle of 3s on and 2s off. Daylight sensor Daylight sensor means the daylight threshold to enable or disable the sensor function. "Disable": The sensor works always, even during daylight. w50lux": The sensor works only in twilight. w10lux, 2luxw: The sensor works only in the dark. Stand-by period This is the time period that the lamp remains at a low light level before it is completely switched off in the long absence of people. means bi-level dimming control, the fixture never switch off. Stand-by dimming level This is the dimmed low light level you would like to have after the hold-time in the absence of people. -

48V smoke detector with relay output is a fire safety detector device. It is widely used for Telecom or Mobile's machine room or computer room of factory or electric power. When it detects smoke, the detector sent a relay signal to fire alarm system to remind with LED lit on. Features: 4 wire interconnection 48V DC powered Frosting plastic High sensitivity To Set NC or NO Description: Working voltage: DC48V Static current:

5.8GHz C-band microwave. Input voltage: 12 - 24V DC . Input current: 30mA. *0~10V / PWM output signal. Super compact size(o50 only), easy and small enough to be used built-in. Specially designed for UFO highbay fixtures, shoeboxes, wallpacks, simple plug and play. If the lighting fixture manufacturers / contactors do not want the sensor function, they just need to easily remove the sensor head and put the cover cap on, the fixture becomes standard non-sensor control fixture.
