{tab Overview} 100mm (4") 5W 100V White EWIS One-Shot Ceiling Speaker 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 anddispersion 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. Features Excellent speech intelligibility Engineered to meet Australian Standard AS1670.4 High quality speaker driver developed for BGM, paging and emergency warning applications Patented 3 way latching ensures a neat, sag free installation. Fitted with 4 way wire protect terminal block for loopin, loop out wiring as required by Australian Standards. Fitted with cable restraint plate and transformer safety cover as required by Australian Standards. Fitted with supervisory capacitor for line monitoring. High impact styrene grille. 5 year warranty. 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 2168C 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 soundpressure 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. The Labour Saving One-Shot® Mounting System Redback® “One-Shot®” speaker unitsinstall in seconds providing substantial labour cost savingsfor 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 gyprocktiles, mineral fibre tiles or fixed gyprock ceilings. A neutral white RAL colour provides an architecturally unobtrusive finish to virtually any installation. Installation Guidelines The C 2168C 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® clipssecure 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. {tab Specifications} Power taps: 0.33, 0.66, 1.25 , 2.5, 5W SPL 1W @ 1m: 92dB @ 1KHz ±2dB Freq response: 100Hz - 15kHz Ceiling cutout: 140mm Ø Note: All SPL figures are measured at 1KHz +/- 2dB. *Specifications are subject to change without notice. {/tabs}
