OPTIONAL CONNECTIONS
Activation of auxiliary devices with NHEA Plus SE terminals:
Continued overleaf
To activate a second lock release, a TF-104 transformer is required.
Auxiliary device activation requires the use of an SAR-12/24 relay unit. If the feature is shared by all terminals,
connect their A1 terminals; if, however, each terminal has its own feature, use an SAR-12/24 relay for each one
and do not connect their A1 terminals.
This function is activated when button
of the terminal is pressed at any time (regardless of whether the terminal is
in standby or function, call, communication or intercom mode).
The most common applications are activating the stairway lights and opening a second door.
The neutral of the lighting power supply is arranged serially through the contacts of the SAR-12/24 relay and the
maximum consumption of the element to be connected does not exceed 1.8A.
