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
simply using LINE terminals – RJ connector or
2N Helios Force/Safety
®
terminal block. The advantage is that
requires no power
2N Helios Force/Safety
®
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
®
sends an acoustic signal on having been connected to a line (or after
Force/Safety
having been disconnected from the line for a defined period of time).
