For any scene, the following three settings affect the light level due to occupants’ motion.
- Initial time: Time the fixtures will hold the scene before the lights turn off when there is no motion
- Switch type: Depending on the switch type, the fixtures turn the lights to either minimum or maximum light level (as defined in the profile) when it detects motion.
- Auto-on/Auto-Off: Lights turn on when motion is detected.
- Manual-on/Auto-Off: Lights turn on when a button is pushed on the ERC.
- Active Motion Window (in profile attributes): The length of time to hold a light on after motion has not been detected.
To view the Initial Time and Switch Type of a switch, select Facilities > Groups > Switch > Edit.
To see the Active Motion Window value for a sensor in the profile, double-click a sensor on the floor plan or view by selecting the profile template from the left panel applied to the group of sensors.
- When a scene is turned ON from an ERC, the fixtures turn the lights to the maximum light level defined in the profile. After the initial time expires for the switch, and if the sensors do not detect motion within the active motion window (extension time), the light levels return to the minimum light level defined in the profile.
- When a scene is turned OFF from an ERC, the fixtures turn off the lights. Lights remain off during initial time plus active motion window irrespective of motion detected.
Depending on the switch type, the fixtures turn the lights to either minimum or maximum light level (as defined in the profile) when it detects motion.
- Auto-on/Auto-Off: The fixture turns the light to a maximum level defined in the profile settings when it detects motion.
- Manual-on/Auto-Off: The fixture continues to set the light at a minimum level defined in the profile settings until a button is pushed on the switch (ERC).
If the initial time is set to zero, then the fixtures will transition to auto-off after twice the maximum active motion window period defined in the fixture profile. For example, if the active motion window is set to 15 minutes in the fixture profile settings, and the initial time is set to zero in Switch Settings, then the initial time is (2*15 minutes). This implies that when a scene is selected from the switch, the scene continues for 30 minutes and then applies the lighting profiles defined for the fixture. To continue the scene for a longer period, increase the initial time. Increasing the initial time delays the fixtures to get into profile mode, which ensures energy savings.
