Senpeirl On / Off

Hi There

I seem to have misplaced my course notes and am struggling to perform this simple operation.

Would like the blocks and logic to switch on a light with movement and for the light to stay on while the PIR senses movement and then to switch off the light 3 minutes after last movement. Have tried using a timer, but this is not a very elegant approach and doesn't really assist with energy savings. What is best practice here?

Thanks a ton!

What you're describing is standard PIR behaviour and the Multisensor is set up to do this out of the box.

Try re-setting your unit back to the factory default settings and then assign a group address to the PIR, i.e. Virtual Key 1 group. If the group address doesn't turn on when there's movement then it's most likely because the measured light level is above the Target light level setting. You can check this on the Light Level tab of the UI.

The default time-out is 5 minutes however you can change this by clicking on the small button just to the right of the PIR Day Move or PIR Night Move Function drop-down boxes.

 

Thanks

Hi Newman

Thanks, I got that, but the problem is at the end of 5 min the light goes off or fades at 8 sec in this case even when someone's on the bog and they have to wave their hands to get it to come up again. I know this sounds very simplistic, but shouldn't the sensor's constant triggering keep resetting the time out to 0 so that the light will only go off 5 min after the last movement? If this is TRUE then mine is not behaving correctly...? The red LED is always triggering which means it is sensing the heat, but goes off nevertheless...

Cheers

The red led is indicating that the timer is running, not sensing heat as you say.

The sensor works by turning on the light using the PIR Night Move then it will retrigger the timer when it senses movement using the PIR Day Move.

The best thing with these sensors when programming them is to reset the unit to default and start again. Just start with something simple then work your way up.

 

If the light starts to fade out / switch off after a period of time then it means most likely that the sensor hasn't detected movement during this period of time.

Things to check or try:

• The PIR Day Move and PIR Night Move Functions should be both assigned to the same group address.
• The configuration on the Occupancy tab is set to the default.
• Potentiometer settings may be reducing the PIR sensitivity. To rule this out go to the Global tab and just assign the Potentiometer functions to Unused.
• Check that the light level sensor is working. The current measured light level is shown under Ambient Light on the Light Level tab.
• Make sure a lens mask isn't fitted and obscuring detection in some directions.
• The home owner may have an absolutely riveting book, causing them to remain motionless for long periods of time. Suggest you substitute it with something like Woman's Day. When they fall asleep due to boredom they will fall to the left or the right. This should create sufficient movement to be detected by the PIR.

Are you sure it's not the orange LED blinking? The red LED in the 5753PEIRL is used for the Light Level Maintenance feature which is a different feature entirely. If it is a 5753PEIRL there also should be a blue LED that is steady on when the PIR is enabled.

As filpee says, the orange LED blinking just means that the timer is running. Each time there is movement detected the timer is re-set and the count is re-started.

 

Thanks Newman and Filpee

I've just checked my Toolkit database and it's a SENPIRIB. Does this unit work the same or similar to the SENPEIRL?

Looking fwd - like the crack about Women's Day btw

Cheers, thanks!

The SENPIRIB is a much simpler unit without lots of the features the Multisensor has. Being simpler, it's also a lot easier to program. That also reduces the chance of a configuration problem.

Like before, you can still check a few things, although most of the things I mentioned previously don't apply (except Woman's Day).

• Check to make sure that you've got things like the box called "Use same response settings as 'Day-time Movement" checked on the UI.
• Re-setting the unit back to all the factory defaults and then selecting the group address and time-out values again is a good idea.
• The PIR sensitivity is not adjustable, the potentiometer only controls the Light/Dark threshold.
• Try rotating the unit slightly. It may be that the movement on the throne is not crossing a boundary between sensing zones for the PIR.

Failing all those, it sounds like the sensor simply isn't picking up enough movement in it's installed location. As a test, you can try programming the light in the throne room to the Security function of the unit. The sensor will then pulse the group address on and off when it detects movement.
