When used with a Bosch 420 Series detector base, the strobe can be used as a stand-alone device. It also allows automatic component identification, address assignment support and functional security in the event of cable interruption or short circuit.
The Strobe 420 Series is easily integrated into LSN systems by a straightforward power connection through the LSN loop. This, plus a low current consumption of 6 mA, facilitates planning of a new or existing fire alarm system and connection of a large number of devices to minimise installation effort, says the company. The unit has a tamper-proof housing that can only be removed by a technician.
The new strobe complies with the EN 54-23 standard - applicable in all European Union countries. Visual fire alarm devices are mandatory in most countries for facilities where people with partial or full hearing impairment are employed or are gathered.
