Batteries calculation ?

Benz... I'm not totally sure but my best guess (relating to the mk3 alkaline devices) is this....

I think the devices are pre-programmed to send out there battery status maybe every 24 hours. There is no timer involved in the panel whatsoever.... the panel does not display any battery information or percentage of battery left until the panel sees a low battery signal from a device.

It's EMS who said there is timer for batteries the one giving the left batteries percentage through 'device data base'..., and as usual they drop very thin droplette of info each time I call them to seeking advise, they don't want to give more details, my last interpretation in the previous post was based on the role of the microprocessor in general combined with, what I received from EMS...etc

I hope one day I can get in touch with them, to discuss things in details... but I am pretty sure they don't want like any manufacturer, to give further secrets of how the system is designed to operate... etc

Just to mention the timer of each device, must be embeded in the devices itself and not in the panel, the one in the panel may be for the panel batteries... etc we are just guessing according to the available knowledge... etc

No the panel batteries are monitored in the usual manner.

There is a difference between lithium (mk 1) powered devices - you will get a % left in the device database as you say.... but alkaline powered devices (mk 3) don't deliver any battery info to the panel so you will never see a % left.

You will only get a low battery warning from a mk 3 device (or batt A/B/C etc)

As said the "timer" is embedded in the lithium battery boards.... the "% left" is the panels interpretation of the battery info received each 24 hours. Hence EMS issued a firware upgrade about 6-7 years ago when we found the battery life (according to the panel) was nearly zero after around three years... after the upgrade the battery life was up by around 40%.....????!!!

From where did you get that, don't tell you paid them special dinner to get this info, but if you have any secret's guides then please supply us :)

Means now they are supposed to run for five years then, isn't? :)

Most of the info is gained from working with the systems on a daily basis for about the last 10 years....and through taking their technical bods out the back and giving them a good kickin till they talked....!!

Allegedly so....

In all honesty they used to... but they had all sorts of battery problems a few years ago when the manufacture changed from England to France and the quality of the batteries dropped off the scale.

We tell everyone to expect 4 years maximum.... unless they're using voice sounders and they are only 2.5 years....!!!

Are you blaming France of its bad batteries quality ?

It was a French scientist, who first invented VRLA (Valve Regulated Sealed Lead Acid) batteries a while ago! :D

VRLA had first been invented in 1859 by ‘Gaston Planté’ and first demonstrated to the French Academy of Sciences in 1860... etc

Indeed Kurnal :)

George Leclanché was born in Parmain (France) in 1839. He was the son of Léopold Leclanché and Eugenie of Villeneuve. Leclanché was educated in England. He returned to France to continue his study in the Central School of Arts and Manufactures. After completing a technical education in 1860, Leclanché began work as an engineer. Six years later he developed his battery, which contained a conducting solution (electrolyte) of ammonium chloride, a negative terminal of zinc, and a positive terminal of manganese di. In 1866, Georges Leclanche patented a new system, which was immediately successful.

You lot have to much time on your hands, Has anyone got a programme that will do the calculations.
