The new design improves even further on what was already the world’s fastest installing speaker and grille combination. The new single piece grille is a revolution in injection moulding, which required a marathon effort on behalf of Altronics designers and plastics machining experts.

The One-Shot Rat-Trap MK II offers installers considerable labour savings.

Altronics field tests indicate a time saving per unit of around 8 minutes, over a traditional screw fixing speaker. This equates to a $6 to $8 cost saving.

Traditionally speaker grilles required screws or special fixings. Many generations later, the One-Shot Rat-Trap has eliminated the need for fasteners thanks to a spring loaded integral clip system which has changed the way sound professionals install commercial speakers.

The grille is paired with the CC2099, a customised 100mm (4″) PA speaker driver and 100V line transformer, offering excellent speech intelligibility for BGM, paging and emergency warning applications. The transformer offers 5 power tappings up to 5W and is fitted with a 4 way terminal block, line monitoring capacitor, transformer cover and cable restraint, as required by the Australian Standard AS1670.4. The driver offers excellent frequency response and SPL of 92.7dB (1W/1m @ 1kHz).

The One-Shot Rat-Trap is a 100% Australian designed and manufactured product and is a registered design. They are used extensively in hospitals, office buildings and shopping centres – anywhere commercial public address or fire and evacuation (EWIS) systems are in use.
