EST3 system i found in a mall in Croatia. really diverse system. Has a suppression part awell. also has voice evac.
Older EST addressable call point
EST SIGI-270 which replaced an older EST call point
STI stopper push button for suppression abort and EST SIGA-278-REL addressable suppression release pull station. This was for some sort of mechanical rooms in the parking garage.
EST integrity ceiling speaker strobes. These were the main source of signalling in the upper floors. Some places had these on the wall with ceiling strobe.

KAC ema sounder. These were used in the underground parts of the mall.

KAC ema sounder in the parking garages. These were the signalling for the parking garage. most of these where next to the CO alarm sign.
EST SIGA-PS, EST led indicator and EST integrity speaker. this was the average installation in a shop.
EST SIGA-PS, System Sensor led indicator and EST integrity speaker. This was a little newer install as the LED indicator isn’t EST. It is an older indicator though as the LED is red not clear.
Either a SIGA2-PS or a SIGA-PD. can’t tell as the cover was on at the time of this picture. this was in a shop where the space was renovated.

Siemens conventional sounder and yellow conventional call point for fire door/curtain activation. these doors are now redundant as the area which they were protecting were sealed off but the panel controlling the doors was still active.
EST led indicator for elevator shaft detector.
Quite interesting system with American elements.
