Addressable Sounder

Product Details:

FNM‑420‑A‑BS Base Sounder, Indoor
The Base Sounders Indoor are used for signaling an alarm directly at the fire location.
They can be employed either as base sounders or stand-alone sounders. Functions The device allows to select 32 types of alarm and evacuation tones (including DIN tone 33404, part 3) for different requirements. You can adjust the sound pressure by five levels according to the operational environment. Depending on the tone type and volume set, the sound pressure varies between 65 dB(A) and 92.1 dB(A). Sounders of the same LSN loop and with the same tone type provide immediate synchronization. The device maintains LSN loop functions in the event of wire interruption or short-circuit thanks to two integrated isolators. Change of the device settings can be done in the FSP-5000-RPS programming software.

Morley sounder - WSOPRN05
Morley-IAS’s new modular range of Intelligent AV warning devices provides easier system confi guration and fl exibility. A common base across AV and detectors is available, allowing for easier installation and ordering. These devices are all available with isolators, providing you with a fl exible approach and allowing for easier fault-fi nding on the loop. 

Individual tone and volume settings and sounder tone synchronisation can be adjusted from the panel enabling the sound intensity to be adjusted to suit the application. The common installation base , B501AP is supplied with a shorting spring.


This allows for the continuity of wiring to be tested before installing any devices. The Morley-IAS devices can then be fi tted at the fi nal commissioning stage, reducing the risk of damage during the fi rst fi x. At fi nal commissioning the device is simply twisted into the base and the installation is complete.
