Approved for AS ISO7240.24 installations. We’ve refined the One-Shot even further with the new V2 One-Shot fire speaker. This version eliminates the cable glands entirely, streamlining the cabling process during installation. Plus a pluggable terminal block simplifies the cable termination. It maintains the low profile design of earlier series with just 70mm depth. Steel powdercoated grille offers a premium finish with an ultra thin bevelled edge.
This range of speakers have been engineered to meet the requirements of evacuation and occupant warning paging systems. The high efficiency speaker and transformer combination ensures high SPL, wide frequency response, superior speech intelligibility and reproduction for mission critical applications. All components of the fixture are manufactured from high quality, long lasting, flame retardant material and tested to the rigours of the new standard. On site installation will be simple and straight forward using the pluggable terminal block and cabling channel in the rear housing. Finally the speaker will just ‘snap fit’ into the ceiling. Far easier than competitors models being offered on the market.
The Labour Saving One-Shot® Mounting System
Redback® “One-Shot®” speaker units install in seconds providing substantial labour cost savings for the professional installer compared to traditional mounting methods. The One-Shot system utilises a 3 way spring latching system which retains the speaker in the ceiling hole. Each latch is set like a trap before installation into the speaker hole. When the speaker is pushed into the ceiling, the latches spring open, securing the speaker in place. The snap clip material is formulated to retain long service life strength and spring action, ensuring a firm vibration free fit to either gyprock tiles, mineral fibre tiles or fixed gyprock ceilings. A black RAL colour provides an architecturally unobtrusive finish to virtually any installation.
