Which manufacture/brand of battery are you using?

 

This is a lithium battery but only lasts for the amount of time its been used, is the door opened often?

Joe

lithium battery er34615m/w200 3.6v.the front door of the house is the main entrance so is used often but not when alarm is activated.

Customer: replied 3 years ago.


The alarm is only activated when we go to bed at night or when we are away from home which is,nt very often.

Expert:  Joe replied 3 years ago.

Brian,

 

That is correct but the battery is still working in the unit as this is wireless, the alarm is just off, the unit itself still knows every single time the door has been opened and thus is often can drain the battery down... That's why I was asking.

 

The battery provides voltage at all times to the unit.

 

Thanks,

Joe

Expert:  Joe replied 3 years ago.

Brian,

 

I am not fully certain on how long the battery should last as that is never something that is given on the devices, but based on its amount of use it could be draining faster then one not used very much, it is still wireless though so uses more.

hi joe


 


the problem is the battery in the outdoor siren,i can't see how using the entrance would effect the battery as there is no pir sensor on it,i do or may think it is a faulty siren maybe as this is the 4th battery we have used in under 2 years

Brian,

 

This is because the model/part number you provided of which was MCT-302 is a door/window contact and is not an alarm... what you provided only sends a signal to the alarm station letting it know a door or window is open/closed.

 

If it is the siren then that has to be a different part number then the one you provided.

hi joe


 


sorry made a mistake,the part no for the siren is mcs-730 which I believe is for the external siren.The battery in this siren is draining every 3-4 months


 


thanks again

Brian,

 

Ok that changes things as that is a different unit and it has a "rated" battery life of around 3 years. Are you only using 1 battery or 2 as the 2nd being optional?

 

Is the keep alive led set to on or off?

 

Thanks,

Joe

Customer: replied 3 years ago.


hi joe


 


only one battery being used looking at it its only designed for 1 battery,can you explain where the keep alive led button is in the external siren


 


thanks


 


brian

Expert:  Joe replied 3 years ago.

Brian,

 

The led keep alive activation switch is located on the bottom of the unit, the unit has an optional slot at bottom for a second battery. Here is the manual:

hi joe


 


led keep alive led is switched off,so have you any other ideas to why maybe battery keeps draining prematurely


 


thanks

Expert:  Joe replied 3 years ago.

Brian,

 

Not at all, either try a 2nd battery as well or I would exchange/replace it. Manufacture calls for 3 years even at that it should last close to a year. There's really nothing else unless going off a lot that is going to drain it.

 

Thanks,

Joe
