Designed to meet AS ISO7240.24:2015. A lower profile version of the C 2170. At only 65mm overall height, these models are ideal for low profile ceiling spaces. It features flame retardant housing material, sealed cable gland entries and a tuned PA driver to suit the new approval requirements.

Note, this version differs from the C 2161 only in the type of sealing used for cable entry. This model features a press fit rubber push through grommet.

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. Rubber grommets and terminal blocks will make on site termination easier than other competing products. 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 “Rat-Trap” version is the first “One-Shot®” to utilise a retaining 3 way spring latching system. Each latch is set like a rat 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 neutral white RAL colour provides an architecturally unobtrusive finish to virtually any installation.
