Contractor shall follow applicable NFPA/ DIN/ VDE standards for detector numbers and placement. That means, detectors shall be added.

As a compensation for the non-operational sprinkler system, every room shall have at least one smoke detector. Depending onthe room size, multiple detectors shall be installed.

See SOW section B5.02.

4 Fire Alarm System May an additional fire alarm control panel be installed for the additional detectors and alarm devices? Due to bidder questions the scope of the project regarding the fire alarm system was changed. A new fire alarm control panel will be installed. All devices shall be connected to the new fire alarm control panel.

See SOW section B5.02.

5 Fire Alarm System Who assumes liability for the existing system, given that it does not comply with valid regulations? Due to bidder questions the scope of the project regarding the fire alarm system was changed. A new fire alarm control panel will be installed.

6 Fire Alarm System Should the new doors be controlled by the fire alarm system? No, the new doors with hold open devices shall not be connected to the fire alarm system.
