Original Press Release:

Sound Detection Technology Maximizes Safety and Security

Jeron Electronic Systems Inc. announces the release of the Sentinel(TM) Sound Detector Substation for the Spectrum® 430/460 Intercom System. Calls from the Sentinel station to the master station are placed upon recognition of a qualified audio event, such as a scream, a yell for help, or other distress call, or by pressing the call button. The tamper-proof speaker and call button combined with heavy-gauge, stainless-steel construction make this station ideal for use in parking garages, correctional facilities, and other areas where the station may be subject to physical abuse.

Programmable attributes such as sensitivity range, frequency range, sound event qualification and call window times, extended sound reject and ambient adjust times, and the number of detected sound events work together to help eliminate the placement of erroneous calls by noises such as car horns or sirens, and ensure that screams or other distress signals are recognized and place calls.

Since ambient noise levels may differ depending on time of day, sensitivity is independently adjustable for both day and night modes of operation. Sentinel stations may be programmed to place two different priority calls, one when a qualified audio event is detected, and the other by a button press, allowing the attendant at the master station to quickly assess the call and take appropriate action. Sentinel attributes are centrally programmable using Windows® based software. No mechanical adjustments are necessary.

Sentinel stations are available in two and three-gang models. No additional wiring is necessary to support Sentinel functions. Sentinel stations connect to a Spectrum 430/460 Central Exchange using single-twisted pair wiring, allowing easy replacement of existing substations with Sentinel Sound Detector substations.
