HIR28DCVFC with on/off relay control
HIR28DCVFC is a PIR standalone motion sensor, On/Off control with relay output.It’s voltage-free contact which is NO relay (normally on). Designed with a low profile or aesthetically demanding architectural projects providing a high quality sensor for simple on/off occupancy control or providing semi-automatic (absence detection) control.
An intelligent photocell is also included to prevent switching of the lights when natural daylight is availible.
Set-up of the sensor is carried out using a remote control handset with program memory allowing one-key commissioning where common settings are used for multiple devices.

Functions and Features
- On/ off Control
This sensor is a motion switch, which turns on the light upon detection of motion, and turns off after a pre-selected hold-time when there is no movement. A daylight sensor is also built in to prevent the light from switching on when there is sufficient natural light. - Intelligent Photocell (daylight detection prior to motion detection)
The built-in photocell will also automatically turn off the light when the ambient natural light exceeds the programmed lux level for more than 5min, regardless of whether motion is detected or not.
With sufficient natural light, the light does not switch on when presence is detected.
With insufficient natural light, the sensor switches on the light automatically when presence is detected. 
The sensor switches off the light when natural light is sufficient, even with presence.
Settings (Remote Control HRC-12)
Permanent ON/OFF function
Press button “ON/OFF” to select permanent ON or permanent OFF mode.
* Press button “AUTO”, “RESET” or “Ambient” to quit this mode.
The mode will change to AUTO Mode after power failure.
Reset Settings
Press button “RESET”, all settings go back to default values as below:
Detection range: 100%; Hold-time: 5min; Lux disabled
Sensor mode
Press “Auto Mode” button, the sensor starts to function and all settings remain the same as the latest status before the light is switched on/off.
SEMI-AUTO mode
This button is disabled.
Daylight threshold
Press buttons in zone “ Daylight threshold” to set daylight sensor at 2Lux/ 10Lux / 50Lux / 100Lux / 300Lux / 500Lux / Disable.
Ambient daylight threshold
Press button “Ambient”, the surrounding lux level is sampled and set as the new daylight threshold.
Hold-time
