Here is the situation: a small business with one single 42U rack in a room for "IT purposes". The room is about 14' long X 7' wide with 10' ceiling. There is a semi partition wall (with a door) that separates the room into inner 1/3 and outer 2/3. The rack is in the inner 1/3. The outer 2/3 is used as office space with an employee sitting there normal business hours. The partitioning wall is open at the top and bottom because the two spaces share the same AC - it is currently not possible to completely seal off the partition wall because of the AC. The only egress is the door in the outer space - the door leads to the hallway in the building. No window.
There is no fire suppression in the room - there is a smoke detector in the room that is hooked to the building central fire/security panel. The building has smoke detectors many places for fire alarm but not really any other suppression.
One of the business' clients that has data on the servers requested a gaseous fire suppression device installed in the server room. A local fire contractor surveyed the room and made a proposal. The proposal uses a Novec 1230 tank sized for both spaces, with auto actuation by heat detection (4 photoelectric detectors) and piping/fitting/nozzles. Also a control panel, electronics for manual triggering, manual abort of triggering, horn and bell in that room for warning of triggering, connection to the central panel to set off the build alarm before the tank triggers, and backup battery etc. The proposal considered the area as normally occupied because the top and bottom of the partitioning wall are open. The proposal cost is $14K.
The management balks at the cost.
Is the proposal necessary and reasonable? Somebody in the company has seen some devices like a single tank hanging on the ceiling without any piping or electrical stuff, triggered by heat, would be only a couple of hundreds dollar. Will that be a feasible alternative?
