D. Night bell Over Page
C. VOX (Page Port) Mode
FXS Power Assist (Ring Trip) Mode - Power Required
In this mode, the unit waits until audio is detected, then activates the relay contacts. If more than 2.5 seconds of
silence or a busy tone (default timer > 16 seconds) is detected, or the default timer expires, the unit releases the
relay. There is no pre-page beep in this mode.
If the unit is installed in FXO or VOX mode and not currently paging or providing a CPC, a momentary closure
on the Night Bell input for 50mS or more will trigger a 1 second pause followed by relay activation, a 1.5 second
warble tone, and relay release. A continuous closure on the night bell input causes the 1 second pause, 1.5
second warble tone cycle to repeat until the closure is removed.
Some VoIP products provide a low power ring signal designed for electronic phones that adaptor-
powered equipment can detect easily, but line-powered equipment has trouble using to activate a relay.
In this case it is recommended to use FXO (Loop Start) mode if possible by changing to an unused
trunk input, otherwise connect the equipment as shown in the special “FXS Power Assist (Ring Trip)
Mode”.
In this installation, a short page may be heard when the unit is powered on, but will then function as
normal.
