GNExC1 Xenon Strobe & Alarm Horn Combination 1-23-110

Description

The GNExC1 is comprised of the GNExB1X05 beacon producing over 117cd effective – a high output Xenon strobe flash required for safety signalling and either the GNExS1F, GNExS1R or GNExS2F alarm horn sounder. The beacon features a field replaceable colour filter which enhances the strobe and is constructed from UV stable PC. The alarm horn sounder offer sound level outputs of up to 123dB(A) at 1 metre with a choice of 64 alarm tones. The optional GNExS1R alarm horn provides a compact audible solution distributing the warning signal omni-directionally.

The GRP enclosures features a threaded flame path and large termination area – all of which significantly reduce installation time. The 316 stainless steel mounting plate can be surface mounted and is also supplied with pole mounting hardware. SIL1 compliant to IEC61508 (2010) as standard.
