2.3.1
Emergency stop button
The emergency stop buttons are located on the remote control and outside on the technical
room.
When an emergency stop switch is triggered, an immediate emergency stop is initiated in
the training rooms. In this process the gas supply is stopped, all gas-fired fireplaces are
switched off, the fan in C3 is switched to maximum output and the emergency lighting is
switched on.
The smoke removal flap above the flash over (wood-fired) must be opened manually using
the pulley fitted on the inside.
The measuring and monitoring equipment remains operational.
Only when the actuated emergency stop button is set back to its initial position, and, if
triggered via the remote control, when the remote control is switched back on again, can
the alarm be acknowledged using the reset button on the cabinet. After the emergency stop
operation has been reset, the ventilator continues to run for 1 minute.
2.3.2
Gas sensor and X-zone
A gas sensor is installed in the technical room in container 1. Outside the system there are
3 X-zones set up that monitor the hazard area. An X-zone is connected to the system via
cable. If the X-zones are not connected, the fire simulation system automatically switches
to emergency stop mode.
The controllers of the gas sensor and X-zones are located in the cabinet.
The heads of the gas sensors continuously monitor for explosive gases and vapors in the
surrounding air and are factory-set to detect predefined gas mixtures.
When the measured values reach 15 % of the lower explosive limit (LEL), a warning is
issued in the software. At 25 % of the LEL, the fire simulation system automatically
switches to emergency stop mode. As soon as the gas concentration is less than 15 % of
the LEL it is possible to reset the alarm using the reset button on the cabinet. After reset of
the alarm the ventilators continue to run for 1 minute.
The gas sensors can display different basic values due to fluctuations in the ambient
temperature, air humidity or ambient pressure (tolerance ±3%). The initiation of the
emergency stop mode at 25 % of the LEL is still maintained.
2.3.3
Temperature sensor
Temperature sensors are installed in each fire room to avoid personal injuries and damage
to the system. The temperature sensors installed in the fire rooms protect the system
against overheating.

NOTICE
For temperature alarms, only the fireplaces in the area of the respective temperature
sensor are switched off and the ventilation and emergency lighting switched on. The
affected area is defined in advance and can encompass anything from one exercise room
to an entire floor of the exercise area. All other areas not included in the area can still be
operated. Systems comprised of only one area go completely into emergency stop
operation.
