Electronic Siren

ES Siren

The ES siren superior range provides a sophisticated, robust and resilient solution to address wide area mass alert signalling for all industrial, civil, commercial and environmental requirements.

The products are of modular construction incorporating an extremely flexible user configuration software package which allows the sirens to be scaled and tailored to the user’s most complex specific needs including omni or uni – directional sound coverage.

Features

  • Audibility range between 106db @ 30metres for the smallest unit to 127db @ 30metres for the largest unit. Sirens in this range in increasing order of sound output are the ES1/2S, ES1/3S, ES2S, ES3S and ES4S  units.
  • 16 user selectable & configurable emergency signals.
  • Storage for up to & selectable 400 pre-recorded voice messages. (Voice files are stored as PCM-CCITT 8 kHz 8 bits mono).
  • Live PA via a 600 ohm balanced & isolated input.
  • Battery operated from an integral battery pack to overcome AC power failure.
  • User definable schedules for time/date signalling.
  • Silent test facility to minimise nuisance signalling to test the siren.
  • Full control and fault diagnosis of a single or multiple
  • units via an RS485 interface of up to 1.5km distance
  • from the siren.
  • Simple control and fault reporting via 8 VFC
  • opto-coupled inputs and relay output(s).
  • Supports a radio & modem for remote operation via
  • bi-directional integrated RS232 interface.
  • Supports a GPS clock for accurate time synchronisation for schedules via an integrated RS232 interface.
  • Class D 375W amplifier used in the output with self healing short circuit, thermal & over current protection.
  • Option of driving 100V line driver horns in stead of or as well as the standard horns for hazardous area operations and mass coverage within a building.
  • Active alarm signal or PA output via a set of N/O & N/C relay contacts for control of and supplementary devices. (i.e. Strobe beacon).
  • Four configurable VFC opto-coupled monitor inputs. (i.e. AC Power, Cabinet door open etc).
  • Four configurable relays with changeover contacts used to monitor the activities of the unit.
  • Siren activity and fault report log.
  • Minimum alarm signal operating time of at least 6 minutes after a 7 day AC power loss.
  • Supports CMC 4 optional engineer’s activation & supervision panel with microphone input facility.
  • Control cabinet constructed from coated steel as standard or stainless steel on request, (800 x 600 x 250mm), which provides an environmental rating of IP65 and the siren horns are manufactured of cast aluminium.
  • Power supplied by an integral 48Vdc battery pack and an 88-132/176-264Vac @ 47–63Hz power source.
  • Operating temperature range of -20 to +60 degrees C.
