How come a qualified electrian cannot change an HD to SD.
For the record I am putting in Appolo 65 optical detectors which will mean replacing the bases.
Location (mostly) are in middle of room.
I suppose it would be best to keep the HD's where they are next to the bathroom
What do you folk think is a reasonable charge (per SD) to change and commision (incl supple)
Anyone can change a HD to a SD as long as they are competent to do so i.e. they have the correct tools, training, experience and knowledge.
It is unlikely that a general handyman would be competent.
It is possible an electrician could be competent.
It is almost definite that a specialist fire alarm engineer would be competent.
I would budget estimate that the cost per point to suppy, install and commission would be between £35.00 and £50.00 + vat per point (based on a quantitiy of approx. 50 No. Apollo Series 65 Optical and diode bases depending on location of your site and the difficulty of the job, and assuming your existing system is capable and fit to accept the new devices.
