Why is the LED light completely off after the walk test and lockout time?


Yes, it works normally. Things have evolved in the technology of security systems and now it is standard to have any LED turned off on any motion detector (the LED's are now used for walk-testing only), the standard DSC and Honeywell wireless motions also do the same thing.

  • This is a normal function for your motion detector. It's also a great power saving function since most of the current draw on the batteries is when it's transmitting a detection signal so if you're home and moving around it will only transmit every few minutes instead of every second, saving on battery life significantly (up to 5 years on average) but after the 3-minute lockout the passive infrared scans continuously until it transmits another motion signal.
Reason: most burglaries are done by someone who has been there before, if they see the LED then they know the motion will catch them moving in that given spot, then they can "map-out" where it's safe to walk (where the LED doesn't light up) for when they plan to return for a robbery.

You can also make this device "more sensitive" by moving the jumper pin position by the right side battery and having the back mounting plate mounted using the bottom screw presets so it faces slightly downward instead of straight forward.

Helpful tip: Change the batteries every 4 years if you're using Alkaline (dead or not) since the detector was engineered "too energy efficient" and the batteries actually leak and corrode the interior PCB at about the 5-year point on about 15% of the detectors with factory original duracell batteries (from what I've experienced in field service).

User manual for fl09sbk light


It appears this device is rate 10 amps at 230 volts = 2300 watts.
Use at least #14 wire and 15 amp breaker.
Connect wire at connection point on light.
Unit appears to have a transformer, and might make humming sound.
There is override located somewhere on unit. Possibly as a button on the motion sensor

If infrared motion detector requires separate wiring connection, then use following wiring illustration:
http://waterheatertimer.org/images/How-to-wire-motion-sensor-230V.jpg

Motion sensor will probably have 2 settings.
1st setting for sensitivity, so it will not activate when cat walks up driveway.
2nd setting for time duration, selectable from 30 seconds to 7 minutes

Ademco motion detector false alarms


Aside from any sensitivity adjustments, after all a false alarm caused by falling objects, pets or juicy bugs is not a false alarm..it's an environmental mismatch of sensor to the area, some motion detector false alarms are caused by circuit faults, possibly during the install, where the wire terminals were turned too hard and twisted slightly and are not as solid as the manufacturer intended. This twisted terminal mount could cause false alarms when either the power circuit or the sensor circuit loses continuity. Intermittent power (caused by weak/loose/nicked/damaged wiring, a weak terminal on the board or power supply problems could cause annoying faults that are hard to trace. Diligence and a good eye to spot these problems and correct them will help you determine the cause of false alarms.

In the case of wireless devices, troubleshooting is usually limited to spotless battery contacts, good batteries and proper placement.

I have a Bravo 3P pet immune PIR and it says on the connector that the contacts are normally closed. Unfortunately they are normally open. Is there something that I am missing? Even the specs on the...


To work properly, this unit has to have normally closed loop circuit. With power applied, and no motion in its sight, should measure 000 ohms (plus any resistor value in series). When activated..the contact should show infinite resistance(open).
You are only missing something if you're testing it with you in the the motion area.

Trash it otherwise.

How to change the battery on a DSC PIR? I have removed the cover but could not see where is the battery. Thanks


If it is the PIR that uses 4 AA batteries, they are behind the circuit board. Grasp the sides of the board and lift up and away from the detector housing. The batteries should be at the top. See manual at link:

Want a owners manual for Drayton Tempus Three Water heater


The Tempus three actually the controller not the heater itself. It varies from when the unit was made but I see the web littered with people trying to get this info. I trawled the net for a while to try and get a link for you but my best suggestion it to either email Drayton or you can find vartious instructions for the tempus 7, 2 and 1 that might help you figure out how to use yours. I'll keep looking and see if I can get a pdf. put on.

Wiring diagram 3 way motion detector switch I want the motion detector to be in the hot line box, and I want a regular 3 way to turn the light on from the load box. So far I can only get the motion...


Sorry, but you need one extra wire between the switches to wire "the opposite configuration" that you want :-(
That means going into the attic and pulling another cable :-( I can walk you through it if you are willing to do all that work.
The only other solution would be to purchase the commercial version of that motion switch, which would also require a sensor at _each_ switch location :-(
