The Redback One-Shot Rat-Trap is a customer designed speaker and transformer combination. It 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 highly desirable for emergency paging applications.
Modelled on the popular Redback One-Shot design, the ‘rat trap’ uses an ingenious patented spring mechanism that snaps like a rat trap when activated. Includes three retaining clips ensuring the grille fits snugly to the ceiling without sagging or drooping, even in soft ceilings. For best results we recommend using the T 2312A holesaw.
Fitted with 4 way wire protect terminal block, 22µF bipolar capacitor, transformer safety cover and cable restraint plate as required by Australian standard.

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. They simply snap fit to the ceiling by means of the integral pressure clips. 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.
Backed by an industry leading 5 Year Speaker Performance Warranty.
This speaker is covered by our 5 Year speaker performance warranty. Redback PA 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.
Suits EWIS Systems
This speaker and transformer combination is designed for both paging announcements and emergency tones in EWIS systems. Speakers employed in an EWIS installation must comply to AS1670.4. This dictates that the speakers must be fitted with transformer safety cover, cable restraint plate, line monitoring capacitor and 4 way wire protect terminal connection. The Redback C 2150 EWIS speaker complies to this standard.
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® Speakers
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. For reference, the transformer safety cover is imprinted with power selection information.
Installation Guidelines
The C 2150 is fitted with a 4 way wire protect screw terminal block. This is suitable for loop in, loop out cabling. The cable can be secured to the in-built restraint plate with 100mm cable ties. 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.
For 100mm (4”) models we recommend a speaker hole of 140mm. This is easily cut using the T 2312A holesaw.
Frequency response: 100Hz – 15kHz
SPL 1W@ 1m: 90dB
Connection: : 4 way terminal block + 22uF bipolar capacitor
Overall mounting depth: 60mm (less thickness of ceiling).
Note: All SPL figures are measured at 1KHz +/- 2dB.
