Xenon/LED & Horn Alarm Bar

Description

The Ex d explosion proof GNExC2 is comprised of up to 6 × GNExB1X10 10 Joule, GNExB2X15 15 Joule, GNExB2X21 21 Joule Xenon strobe or the GNExB2LD2 multi-function LED beacon with either the GNExS1F, GNExS1R or GNExS2F alarm horn sounder. Factory assembled and pre-wired with or without an Ex d junction box, the connected signals are mounted on a 316L stainless steel plate with optional pole mount kit included. The alarm horn sounder offers sound level outputs of up to 123dB(A) at 1 metre with a choice of 64 alarm tones and 4 remotely selectable stages.

The alarm tone frequencies for the first 2 stages are independently selectable. The optional compact GNExS1R alarm horn distributes the audible warning omni-directionally. The GRP enclosures feature a threaded flame path, a large termination area and provided with stopping plugs in all spare entries – all of which significantly reduces installation time.
