4.2.2 Potential free emergency button (Sensor-2)
The emergency call button can be connected directly to the

X2
plug on the sub-communication unit.
Requirements for an emergency call button according to EN81-70:

Symbol: Bell sublime.

Centre of the button >90cm (<110cm) from cabin floor.

Surface ≥ 490mm 2 .

Panel orientation is portrait: alarm button must be the first button from the bottom.

Panel orientation is landscape: alarm button must be the first button from the left.
Use only small signal switches or relay contacts. Do not use 230 V contact material, since it may not give a reliable contact.
If the emergency button is not isolated, i.e. older panels with only a single alarm contact for the alarm horn, the accessory
EA-NT-IN (
