This one is a very old Gent's system at an office building.
It's 24V DC this time so not instantly 'illegal', but isn't in the best of nick. In the long term I would advise total ripout, but as the building may only have a medium term future at the most (owner may decide to flatten) the client may be reluctant to replace.
Mostly vacant, no high risk uses, processes or user groups.
Questions:
-Could you realistically add smoke detectors? (It's manual only at the moment, but some L5 cover may be needed).
-The battery set up looks a bit poor, would it need a 'proper' fire alarm battery set up or as long as it works would be OK.
-There appears to be no fault monitoring ability, is this essential or could daily battery checks & weekly call point tests with service visits be OK temporarily.
- The call point has had it's glass broken and as no spares remain someone has taken the point off and reconnected it with both wires in the same terminal instead of 2 seperate ones - I assume this is to complete the zone circuit so it still works?
- In the photo with the light switch I assume that there are two sets of wiring in the conduit otherwise how could the lights & alarm be together?
