Product Information

The Apollo Sounder Visual Indicator Base is a loop-powered sounder and visual indicator combined with a standard Intelligent Mounting Base. It is used to signal a fire alarm in enclosed areas.

Electrical Description

The Sounder Beacon Base is loop powered so needs no external power supply. It operates at 17–28V dc and is polarity-sensitive.

Mechanical Construction

The Sounder Beacon Base are moulded in polycarbonate and has stainless steel contacts that accept solid or stranded cables of up to 2.5mm².

Application

The low volume range is useful in areas such as hospitals where a fire alert is initially intended to warn staff only. The sounder is set to the high range for general use.

Synchronisation of tones ensures the integrity of the signal—tones from different sounders do not merge into one signal that could be mistaken for a different tone.

Group addressing is a simple method of alerting an 
entire area or group of rooms without delay.
For systems requiring isolators at every point the built-in isolator saves installation time and cost.

The acoustic self-test means that the sounder listens to itself when it is switched on. If no sound is detected a fault signal is transmitted when the sounder is polled.

The beacon self test is achieved by means of an LED monitoring circuit. If the LEDs do not draw current when the sounder beacon base has been switched on a fault signal is transmitted when the device is next polled.

Device Addressing

ADDRESSING
The Sounder Beacon Base 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 synchronisation address which is embedded in the unit.

Addresses 1 to 111 are used exclusively for individual addresses; addresses 112 to 126 are used for group addressing. Any Sounder Beacon Bases on a loop may be freely assigned to a group. The address for any group must be chosen from the range 112–126.

Addresses 112–126 may be used as individual addresses but only if the 4-segment DIL switch is not used ie, group addressing is disabled. If the 4-segment DIL switch were set to any number other than the default 127, a pre-set analogue value of 4 would be transmitted to indicate a fault.

The Sounder Beacon Bases are normally polled by the individual address. If more than one Sounder Beacon Base is activated it is possible for the sounders to be synchronised with each other.

GROUP ADDRESSING
It may be desirable, in alarm conditions, to switch more than one Sounder Beacon Base simultaneously. To enable this, devices may be controlled as a group and given a group address which is common to all sounder beacon bases in the group. When a device recognises its group address, it will process the output bits but it will not return any data to the control panel on that address. 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 Sounder Beacon Bases will operate only with control equipment using the Apollo XP95 or Discovery protocol. The features of the Sounder Beacon Base are available only when it is connected to a control panel with the appropriate software.
