hi my mate has a cinema with a new fire alarm fitted last week, but we cant see any afd in the fire escape routes or internal passages
the afd is just in the lobby and screen areas

Who specced the alarm and why was the afd required for life safety or property protection?
Take a look at the inspection and commissioning certificate. If its a properly installed system it will identify the spec and system type.
If a life safety system it may have been a requirement to cover a specific building design issue in which case an L4 specification will be quoted with details of what has been provided.
But more likely it should be an L3/L2 system and if so as you say the first consideration for detection should be escape routes and rooms off.
It may be a property protection system to ensure that the fire brigade are called if a fire breaks out whilst the cinema is shut.

As Kurnal mentioned-ask the installing company what Catgeory of system they have installed.

Isn't a specific task like that an L5 system?

L4 = Escape routes only?
