Apollo Integrated Base Sounder with Isolator - 45681-277

Apollo Integrated Base Sounder with Isolator - 45681-277 

The Apollo Integrated Base Sounder (45681-277) comprises a base sounder with integral mounting base and is for use with Discovery or XP95 ranges. It is designed for use in enclosed areas/indoor use.

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.
