Primarily designed for Noisy Environs
normal loud ringing is drowned or is
difficult to hear. The unit gives excellent
"bounce around" from the strobe
light. Easy to install - mount on wall,
plug into power outlet and then plug into
Telephone Line.
During incoming ring, the unit produces
a sound and also flashes a strobe light.
The sound type is adjustable across 32
settings using internal adjustments.
Suitable for direct Telephone Lines and
Analog Phone ports of PABX Systems.

• Power FET Output for Sounder or Light/Strobe Options
• Relay Output for Light or Strobe Options
• Can have Strobe Continuous Power Drive State during ringing cycles and sounder Ringing with the Ring Cadence at the same time
• Relay can follow ringing cadence or HOLD between ring cycles
• Power FET can follow ringing cadence or HOLD between ring cycles (must have Relay HOLD as well to work otherwise follows Relay)
• POTS or PABX Hold between ring cycle period selectable
• Relay can be disconnected via a LINK so as only FET can switch giving totally silent switching for Radio Station Hotlines etc. ie. no relay clicking on Microphone in Studio
• With the PABX Message Waiting Facility it can be used in Call Centres and Hotels etc. for an easy solution to advise supervisor and others that calls are being missed. Adjustable 65Vdc to 100Vdc simultaneous to Ringing Detection. Therefore, for practical reasons can only be used for one or the other.
