Sensor Operation
The RVS sensor is powered by solar energy from natural or artificial light sources. The
solar energy is transformed into electrical energy which is then used as a power source
for the sensor. Powered by two solar cells, the sensor will begin operation without a
battery within 2 minutes of having sufficient light (6 foot candles or 65 lux).
The RCS models are battery powered ( CR1632) and have continuous operation.
The sensor supports the Occupancy Sensor EnOcean Equipment Profile A5-07-01.
The sensor must be within range of any linked receivers or controllers, installed within
80' (24m) of each other. For applications exceeding this range, signal repeaters may be
needed to extend the range.
Operating Sequence
If the monitored space is vacant for a period of time, only the PIR interface will actively
monitor for occupancy. The audio interface will be disabled.
Once the PIR has detected motion, an occupancy telegram is sent immediately and the
audio interface is enabled.
Once the audio is enabled, two timers become active that control the audio interface.
1.
The Audio Enabled Timer is reset with each PIR event and defines the
maximum duration which the audio remains active.
If the timer expires, the audio will be disabled, no other action will be performed at
that time. Once the timer has expired, only PIR triggers can reset the timer to keep
the light on. The default setting for the Audio Enabled Timer is 60 minutes and is not
configurable.
For example: Body motion must be detected at least once an hour to keep the light on.
2.
The Sensor Occupancy Timer is reset every time a PIR or audio trigger is
detected. It defines the time in which an occupancy trigger (PIR or audio) must
be detected to keep the audio input active. The default value for this timer is 20
minutes and it is configurable to values of 5, 10, 15, 20 , 25 minutes or disabled. If
the sensor occupancy timer expires, the sensor will send out a vacancy signal and
40 seconds later the audio will be disabled. The 40 seconds grace time allows an
occupant to use sound to reset the sensor occupancy timer and turn the light back
on.
The audio interface has a sound threshold that when exceeded, will maintain the
sensors occupied state while the timers are active. The threshold is slightly higher than
the background noise level. The background noise level is averaged over a 30 second
window and filtered out. Any other sound louder than this background level will
trigger the audio.
For example: If a fan is running in the background while the space is occupied, only a
sound slightly louder than the fan noise will trigger the audio.
Either the PIR or audio can maintain the sensors occupied state with telegrams being
sent at minimum every 100 seconds. A LED under the PIR lens will blink when an
occupied state telegram is sent. A linked Echoflex controller has an occupancy timer
that is reset only when receiving an occupied state telegram so the lights will remain
on so long as the sensor continues to sense occupancy.
See the controller install guide for details on setting up this timer and occupancy or
vacancy modes of control.
Operating Sequence
The RVS-A/RCS-B behave similarly as the dual tech models; when vacant the PIR
monitors for occupancy. Once motion is detected and the occupancy state is
transmitted to the receivers, the minimum period to the next telegram is > 100
seconds. If no motion is detected in 200 seconds, a vacant telegram is sent. The sensor
will transmit telegrams indicating vacancy every 1000 seconds. So long as linked
