Electrical Description
The integrated base sounder is line powered and needs no external power supply. It operates at 17-28V DC and is polarity-sensitive.
Mechanical Construction
The integrated base sounder is moulded in polycarbonate and has stainless steel contacts that accept solid or stranded cables of up to 2.5mm².
Device Addressing
ADDRESSING
The integrated base sounder responds to its own individual address set with a DIL switch. It also responds both to a group address, set by means of a 4-segment DIL switch and to a pulsed-mode synchronisation address which is embedded in the unit.
GROUP ADDRESSING
It may be desirable, in alarm conditions, to switch more than one integrated base sounder simultaneously. To enable this, sounders may be controlled as a group and given a group address which is common to all sounders in the group. When a device recognises its group address, it will process the forward command bits but it will not return any data to the control panel on that ad dress. If it is required to confirm the status of the outputs of devices under group address control, it is necessary to interrogate all devices in the group at their individual addresses.
Communication
XP95, Discovery and CoreProtocol compatible
Backward Compatibility
The features of the Integrated base sounder are available only when the sounder is connected to a control panel with the appropriate software.
