Door alarm
4.3.5
If the pre-alarm time is exceeded, the door alarm is triggered. This must then be reset with the built-in key switch
or with a new short-term release command. If the door is closed while the door alarm is active, it locks and can be
unlocked again only after the alarm has been reset (except when the emergency button is pressed or emergency
unlocking is triggered). The door alarm is also triggered when the door is opened forcefully.
Unlocked
4.3.6
The power supply to the locking element is permanently interrupted. The door can be passed through without
triggering an alarm.
Locked
4.3.7
The locking element is energized through the door control unit. The emergency door protection is active and
unauthorized people can open the door only by pressing the emergency button, which triggers an alarm.
Emergency unlocking
4.3.8
The TZ300 can be unlocked in an emergency by the fire detection, burglar alarm or hazard alert system. This is a
non-safety-relevant interruption of the power supply to the locking element.
When the BMA, GMA or RWA signal is cancelled, the alarm is automatically reset after 60 seconds.
Direct unlocking (according to EltVTR)
4.3.9
Safety-relevant interruption of the power supply to the electrical lock through an NC contact when the emer-
gency button is pressed.
Fire detection system (BMA), hazard alert system (GMA), smoke and heat

extraction system (RWA)
Alarm triggers
4.4.1
If the BMA, GMA or RWA signal of a door control unit is applied, it is unlocked and a local alarm is triggered (audi-
ble through built-in buzzer and visual through built-in LED). The system remains unlocked as long as the signal is
applied and until the alarm has been reset. See 4.4.3, “Resetting the alarm”.
The alarm is triggered through a floating NC contact. If no BMA, GMA or RWA exists, a 2K resistor must be fitted
across the Fire Detection System input (terminals 2 and 10, orange terminal field. This is the as-supplied state.
If a BMA or GMA system is connected, the 2K resistor at the emergency unlocking input of the TZ300 (terminals 2
and 10) must be removed and connected in series with the NC contact of the BMA or GMA.
Cable monitoring according to prEN 13637
4.4.2
For installations according to prEN 13637 the cable between fire detection system and door control unit must be
monitored. A 2k resistor must be fitted in series with the NC contact at the fire detection system output for this
purpose.
Resetting/acknowledging the alarm
4.4.3
When the BMA signal is cancelled, the alarm is automatically reset after 60 seconds. The visual and audible signal
at the TZ300 goes out and the door control unit locks the door.
The system can be reset before the 60 seconds have expired with the built-in key switch of the TZ300.
To unlock the system after a reset, turn the key to the left for more than one second.
To lock the system after a reset, turn the key to the right.
