Safety
Panel, detectors, sounder, monitored CO2 extinguishers, fire doors and an overview monitor with site plan – and a CO2 system that only floods for a real fire.
A complete fire alarm system like in a real building, with custom 3D models. Everything sits on the same cable network and the panel finds its devices on its own.
The devices
Floods only for a real fire
CO2 is only released when something is actually burning in the room of a triggered detector. Heat, smoke gas, a flare or the call point only raise the alarm. Flooding starts after a 10 second pre-warning with an evacuation tone. Only the nozzles in the fire room blow, and never above 150 kPa room pressure. Once the fire is out, everything closes by itself. On heat without fire the panel switches on the wall coolers in that room.
Every wall and ceiling device also comes with a rear or top connection, picked with the mouse wheel while building. bma testraum in the console builds a ready-made test room. The server and all players need the mod.

New: single and double fire door, fire shutter 2 m and 4 m (FAS fire kit) – airtight when shut like game doors, held open in normal operation, on an alarm in their area warning tone and light, then shut; obstacle detection, emergency opening by hand, reopen after RESET, IC10, paintable. New: overview monitor small and large with a site plan from above (floor plan, numbered devices, legend) and an FAS control desk with list, manual release (two-step with pre-warning), doors, event log with game time and statistics with CO2 used; the key locks operation. Areas (detector groups) for detectors and doors. New commands bma tore, tor, bereich, protokoll, statistik, monitor, loeschen and bma testraum tor. Old saves load unchanged.
New: FAS CO2 fire extinguisher with three monitored holders – wall bracket, glass-door cabinet and floor stand. Removing it or opening the cabinet door raises the building alarm at the panel, never CO2 flooding. The holders refill the extinguisher from a CO2 pipe by amount: without power through a valve, the rest up to 75 % of the burst pressure with the compressor, liquid CO2 included. Safety valve from 90 % of the burst pressure, the canister does not burst, not even in a fire. New command bma loescher. Existing devices and saves are kept.
Alarm sounder and manual call point sit in front of finished walls, labels, LEDs and button stay visible. Wall and ceiling devices can no longer be clicked from the other side of the wall.
All labels on the models now appear in German or English depending on the game language – right away when you switch it in a running game. Device names stay after switching the language (works around a game bug).
Panel, detector, call point, sounder and nozzle also come with a rear/top connection (into the wall or through the ceiling; nozzle: gas pipe only). Pick it with the mouse wheel while building, side stays the default. Existing devices and saves are unchanged.
First Workshop release: panel with display and battery, fire detector, manual call point and sounder, plus the CO2 system with extinguishing tank and nozzles that only floods for a real fire. Wall cooler control on heat, key to block extinguishing, console commands with test room and test fire.
New: CO2 cylinder bank with 6,000 L for small rooms. One Kit (CO2 Storage) builds either the extinguishing tank or the cylinder bank. bma testraum klein builds the test room with a cylinder bank.
On purpose. CO2 is only released when something is actually burning in the room of a triggered detector. Heat, smoke gas, a flare or the call point only raise the alarm. On heat without fire the panel switches on the wall coolers in that room instead.
In a vacuum all sounds in the game are muted. The room has to be sealed and filled with air. bma luft in the console fills a closed room with breathable air.
Removal is a building alarm like a manual call point. Whoever grabs the extinguisher is often in the fire room, where flooding would be deadly. CO2 is only released when a detector in the room sees a real fire. To take an extinguisher out without an alarm, turn the service key on the sign (LED flashes yellow) or write Setting = 0 via IC10. Inserting an extinguisher switches monitoring back on by itself.
Look at the holder, the tooltip names the reason. "NO POWER": the pipe pressure is not higher than the canister pressure, only the powered compressor can do the rest. "NO CO2 in the pipe" or "no CO2 pipe": fill or connect the pipe. "WITHOUT gas canister" or "canister BROKEN": insert or replace it. "OFF": IC10 set On = 0. Other gases in the pipe do no harm, only the CO2 is taken, liquid included. Without power a valve fills as long as the CO2 pressure in the pipe is higher than in the canister. More in the guide.
No. It is only filled to 75 % of the burst pressure, 7,599 kPa at 20 °C for a gas canister. If the pressure rises above 90 %, for example in a fire, a safety valve vents CO2 – into the pipe in a holder, otherwise into the room. Both are configurable with FuellGrenzeProzent and SicherheitsventilProzent.
Area 0 means automatic: only doors next to the room of the triggering detector close. If several rooms should react together, give detectors and doors the same area number at the monitor (Areas tab) or with bma bereich. With AlleToreBeiAlarm every alarm closes all doors on the panel's network. More in the guide.
No. Players, animals and rovers in the closing area stop the door at once; it keeps warning and reports "blocked" to panel and monitor. Once the area is clear for 3 s it warns briefly again and closes. If you need to get through during a fire, click the door: it opens (emergency opening) and closes again after 15 s.
Only in two steps (EXTINGUISH, then hold CONFIRM for 2 s), only within 6 m of the monitor and only if the controls are not locked with the key. The normal pre-warning follows, which can be stopped at the monitor (ABORT) or with bma loeschen stopp. Every release is logged with the player's name. To switch it off completely: HandLoeschungErlaubt = off.
At the bottom of the frame on the side with the two connector stubs: lay the cable on the floor in the cell directly in front so it points into the stub. Each of the two connections takes power and data; one cable is enough if it carries power and is linked to the panel. The panel then counts the door ("Doors 0/1 shut") and it appears with a number on the site plan.
