140dB(A) Wide Area Sounder exceeds pain threshold
E2S, the specialist manufacturer of high output audible and visual warning indicators, offers electronic sounders rated at 140dB(A) at 1m for use as wide area warning devices.
The sounder now has 49 user-selectable 3 stage alarm tone configurations with an output of 105dB(A) @1m; a 4MHz clock ensures that the outputs from all sounders on a loop are fully synchronised.
The IS-L101 beacon uses an array of ultra bright Amber, Red, Blue or Green LEDs to produce a bright flashing warning signal in hazardous areas, giving a far more effective visual warning than traditional Xenon tube beacon alternatives.
The IS-L101 can be used in conjunction with the IS-A105N sounder, powered through the same Zener barrier or galvanic isolator and mounted together or separately.
An "alarm accepted" facility enables the sounder to be silenced for between one and thirty minutes.
When coupled to a sounder, the L101-IS flashes at 1Hz, increasing to 2Hz when the sounder is silenced.
The IS-A105N measures 130mm square, the IS-L101 86mm square, both are sealed to IP66 and typically draw 25mA from 24VDC when powered via a 28V 300 Ohm Zener barrier.
