I received this posting recently which is new to me any ideas.
"I have been asked to look into the possibility of installing fire alarm devices (some sort of illuminated sign linked to either a single detector or the main panel) adjacent to the first and second floor exit doors to inform the occupiers that they shouldn't use that particular exit (there are 2 exits per floor) if there is a fire in the reception area (my understanding is that this area is deemed an unprotected lobby due to its construction).
For the record the above information was given to me by a project manager who was told to install these devices by the local fire officer. I have never seen this set up before and was wondering if it is even legal/wise/possible."
