Compatibility

2N® Helios Force / Safety is designed for conventional, analogue telephone lines and
works regardless of polarity and line parameters (Refer to the Technical Parameters)
and uses tone (DTMF) dialling to be programmed. Normally, it is connected to a PBX
line. However, it can also be connected to CO line or the GSM gateway, providing a
wireless connectivity.

Connection to Telephone Line

Connect 2N® Helios Force / Safety simply using LINE terminals – RJ connector or
terminal block. The advantage is that 2N® Helios Force / Safety requires no power
supply because all power is fed from the telephone line – except for the amplifier,
button backlight and electric lock, if connected. Nevertheless, 2N® Helios Force /
Safety can work without these circuits too (amplifier is bypassed in this case). 2N®
Helios Force / Safety sends an acoustic signal on having been connected to a line (or
after having been disconnected from the line for a defined period of time).
