The Apollo Visual Indicator Base is a loop-powered visual indicator combined with a standard Intelligent Mounting Base. It is used to signal a fire alarm in enclosed areas. The visual indicator base can be used with either a detector fitted or with a cap as a stand-alone alarm device.

Electrical Description

The base is loop powered so needs no external power supply. It operates at 17–28V DC and is polarity-sensitive.

Mechanical Construction

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

Device Addressing

The Base responds to its own individual address set with a DIL switch. It also responds 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, while the synchronisation address, to which all units respond, is ‘0’. Any Beacon Base 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 Base is normally polled by its individual address. It responds as described below.

It is recommended that the synchronisation address ‘0’ be sent by the control panel at regular intervals to align the internal clock of all sounders. The result is that the beacons are synchronised with each other when activated.

NB: Units on two or more loops can be synchronised only if the panel transmits address ’0’ to all oops synchronously.

GROUP ADDRESSING
It may be desirable, in alarm conditions, to switch more than one base simultaneously. To enable this, devices may be controlled as a group and given a group address which is common to all 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 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.

Backward Compatibility

The Base will operate only with control equipment using the Apollo XP95 or Discovery protocol. The features of the Base are available only when it is connected to a control panel with the appropriate software.
