Commercial smoke detectors added to the system, not stuck to a ceiling
Adding detection on a commercial site means the right head, the right base and a panel that knows the address or the zone.
What this commercial job is
Offices often want optical or multi-sensor heads; plant and kitchens often want heat. We will not add a domestic battery alarm and call it a BS 5839 extension.
If the panel is full, out of protocol or unsupported, the quote says so before we drill the ceiling.

Questions facilities teams ask
Can you add two heads to a shop system?
Yes, when the panel and the cable route allow it.
Are battery alarms ever right commercially?
Rarely, and not where the FRA calls for a system. We will say which conversation you are in.
Do you match Apollo, Hochiki and similar protocols?
We match the protocol already on the loop. Tell us the panel.

Tell us the building, the kit you already have, and whether this is a one-off or a portfolio round. We price after that scope — not from a national grid.
