Application
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. Oversized cable glands 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.
Manufacturing & Performance
Redback® drivers are engineered and manufactured to stringent specifications ensuring maximum reliability under all operating conditions. Each driver has a power rating well above the max tapping of the transformer, ensuring reliable operation and excellent longevity. A strict quality control procedure is employed during every step of the manufacturing process. Finally, every finished speaker is 100% QC checked prior to shipping.
About Redback® Speaker Drivers
Each custom designed speaker and transformer combination has been specifically engineered to ensure a wide frequency range and dispersion angle, plus a high sound pressure level (SPL) ensuring excellent music and speech intelligibility; which is critical for emergency paging applications. Each transformer is fitted with multiple power settings which are user selectable via taps on the transformer.
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” utilises a spring latching system. Each latch is set like a rat
trap before installation into the speaker hole (picture A). When the speaker
is pushed into the ceiling, the latches spring open, securing the speaker in
place (picture B).
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.
Installation Guidelines
These models are fitted with a 4 way wire protect screw terminal block suitable for loop in, loop out cabling. The cable is secured via the safety cover cable glands provided. All One-Shot® speakers are designed for fast installation due to the integral pressure clips which grip to the reverse side of the ceiling tile. They suit any 10-13mm ceiling tile, including gyprock, mineral fibre or fixed gyprock ceilings. Redback provide a range of optional tile supports to minimise sag and vibration.
Ceiling support pans: These pans fit inside the ‘t-bar’ supports for the tile ceiling and provide a solid surface on which the One-Shot® clips secure to. Once the hole is cut, these simply slide up into the hole, the speaker is then pushed in until the clips release.
Ceiling support ring: This plastic ‘split-ring’ offers the same protection for soft tiles. With the added benefit of being lightweight and compact. We recommend a speaker hole of 246mm. This is easily cut using the T 2312A holesaw.
