Operating Principles
The XPlorer Base Sounder is a local-area sounder designed for indoor use.
It is powered by the control equipment via the loop wiring to which it is connected. Since the sounder is switched by the remote indicator output of the associated detector no remote indicator facility is available.
Sound Output
A guaranteed sound output of 85dB(A) at 1 metre is achieved at a current consumption of only 3mA. The sounder generates very low current noise so that up to 63 sounders may be connected to a loop.
Tone Frequency & Volume Control
The sounder produces an uninterrupted alternating tone of 990Hz for 0.5 seconds and 630Hz for 0.5 seconds. The volume control can be used to adjust the sound steplessly from 70dB(A) to 85dB(A).
Note: the XPlorer Base Sounder does not have a synchronisation feature or pulsed tone.
Electrical Considerations
The sounder is loop-powered and requires no external power supply. It operates at 17–28V dc.
Protocol Compatibility
The features of the sounder are available only when it is connected to a control panel with the appropriate software.
