Combined beacon and sounder uses little power

November 16, 2004

A new ISB range of compact, IP65, low-current, combined flashing beacon and sounder units is being launched by DG Controls

These are particularly suitable for alarm systems where power is at a premium. All models incorporate a pulsed ring of high intensity red LEDs behind a red translucent polycarbonate sounder horn. The integral 110dB(A) sounder has 32 tones, selectable by internal DIP-switches, with the primary tone energised by a simple 2-wire connection and a secondary tone via a third wire.

Maximum volume can also be adjusted by internal preset.

Two basic housing styles are available.

The standalone ISB-E is built upon the same white ABS base as the popular Series E ‘High Dome’ beacon lamps to retain the traditional look-and-feel of this long-established range of visual indicators.  The ISB-E is also compatible with existing wall-mounting brackets and cage guards.

The ISB-T utilises the same black polycarbonate base as the Series T, U, V and W beacons, with its novel ‘ratchet’ linking system which allows two or more beacons and/or sounders to be clamped together as an integrated unit.

Versions for all popular supply voltages are offered: 12V DC, 24V DC, 115V AC and 230V AC.

Full details and prices, together with fast delivery opportunities, are available from DG Controls –
