Siren without beacon

electronic

The ES siren value range provides a robust economic solution to address wide area mass alert signalling for all industrial, civil, commercial and environmental requirement users who previously found conventional motor driven sirens acceptable for their needs but would like the advantages of battery operation and no 400Vac cabling. The products are of modular construction which allows the sirens to be scaled and tailored to the user’s specific needs in terms of signalling and omni or uni – directional sound coverage. Features Audibility range between 106db @ 30metres for the smallest unit to 121db @ 30metres for the largest unit. Sirens in this range in increasing order of sound output are the ES1/2V, ES1/3V and ES2V units. 4 user selectable & configurable emergency signals. Live PA via a 600 ohm balanced & isolated input. Battery operated from an integral battery pack to overcome AC power failure. Full control 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 5 VFC opto-coupled inputs, (Up to 4 alarm signals and PA) plus siren fault and AC power relay outputs. Supports a radio & modem for remote operation via an integrated RS232 interface. Class D 375W amplifier used in the output with self healing short circuit, thermal & over current protection.
