Designed to meet AS ISO7240.24:2018. A One-Shot horn speaker designed to save installers time and money. Typically to terminate cabling internally on a horn speaker it involves removing three screws on the rear cover, connecting the cable and then re-installing the same screws.
As you can imagine, doing this up a ladder can get quite fiddly! The One-Shot horn eliminates screw removal by utilising a patented twist lock mechanism. The installer simply twists off the rear cover, connects the cabling and twists the cover back on! The labor savings by using the One-Shot horn on a large job are significant.
To make it even easier, we’ve also incorporated our patented dog leg mounting bracket which eliminates the need to separate the horn from the bracket during installation.
The One-Shot horn is primarily used for fire and evacuation systems where a high degree of speech articulation and program clarity is paramount. Typical applications include schools, train and bus stations, airports, car parks and plant rooms.
Note: This updated model requires no additional equalisation to comply with the Australian Standard.
