Blue Flashing Light On Smoke Detector

This is the second Nest thermostat I have purchased along with a Nest Protect smoke and CD detector. I moved my original Nest to replace an upstairs old thermostat when the new 3rd gen Nest came out. The Nest does everything advertised and more. I highly recommend any of the Nest products.

[This review was collected as part of a promotion.] These are great for use on a smoke detector, will last a long time before replacing

[This review was collected as part of a promotion.] I get these batteries for my smoke detector, and I'm so happy with this brand. They are long lasting and great!

Works as advertised! It's responsive and easy to use. My only minor complaint is the flashing blue light which can be a little annoying in a dark venue But, I realize there has to be some way to know that it's on

Replaced Optex 40 X pri with Bosch Blue Line detectors. Bosch is quite a bit more sensitive and gives better coverage. These are great atributes for a good alarm system. Did not use the tamper portion of the detector. I have a 4 wire lead to the detector. Red to plus, black to neg. and the two other leads to the n/c terminals. Polarity is of no concern as you connect the n/c wires.

but it is unsettling to have the upstream light flashing

5 stars! Stable and very easy to adjust level with slider on.

Awesome smoke !! I used it for Halloween!!

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

Great size, love the built in light (it has flashing mode for some reason, just if you need to give someone a seizure on a film set?) I have always wanted this Porta Brace bag but kept talking myself out of it. I finally pulled the trigger on buying one and I'm glad I did. Sometimes I have a small lens in it if i am shooting an event with a smaller camera, but on a full set I kit it out with all the tools I'll need. for camera department. If you are on the fence about it, do it.
