The Zeta addressable Securetone 2 combined sounder & flasher has a low profile design which makes it ideal for locations where sounders are required to be unobtrusive.It is designed to work with the complete range of Zeta addressable control panels. It also includes a short circuit isolator which minimises the number of devices which would be inoperative in the case of a short circuit on the loop.
The sounder is supplied configured to it’s maximum volume. However there is a potentiometer which may be used to adjust the sound level if required. An 8 way DIL switch is used to set the address, where switch 8 is the shadow operative switch. When in the position ON, the sounder will behave normally. When in the OFF position, the sounder will listen to commands without answering to the panel. This allows multiple sounders to be configured at the same address to allow for synchronised sounder operation.
The Fyreye MkII optical smoke detectors use a pulsing IR LED & photodiode to detect IR scatter caused by smoke entering the chamber.
