XP95 VAD Base with Isolator

Product code: 45681-709APO

45681-709APO - XP95 VAD Base with Isolator
The XP95® Visual Alarm Device (VAD) Base incorporates a loop-powered VAD with a standard mounting base. It is used to signal a visual fire alarm warning in enclosed areas. The XP95 VAD Base can be used either with a detector fitted or with a cap for operation as a stand-alone alarm device. The VAD Bases are supplied with a built-in isolator. A version without an isolator is also available.

Brand Information

The XP95 range of analogue addressable fire detectors uses tried and trusted technology to give the best performance, and has unique features that benefit the installer and the end user. It is suitable for medium-to-large applications with simple installation requirements. As it operates using digital communication, XP95 has a high immunity from corruption, and is, therefore, often preferred in a large system where life safety is critical. XP95 products are frequently used in commercial, industrial, financial, government, IT/telecoms and healthcare applications.

Electrical Description

The XP95 VAD Bases are loop-powered so needs no external power supply. It operates at 17–28V DC and is polarity-sensitive.

Mechanical Construction

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

Device Addressing

ADDRESSING The XP95 VAD 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 VAD 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. GROUP ADDRESSING It may be desirable, in alarm conditions, to switch more than one VAD Base simultaneously. To enable this, devices may be controlled as a group and given a group address which is common to all VAD 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

Apollo XP95

Backward Compatibility

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

Additional Information

SYNCHRONISATION It is possible to synchronise the sound and flash outputs of the VAD range of bases connected to a loop. Other alarm devices, including the 100dB Sounder, the Integrated Base Sounder, the Intelligent Base Sounder, the Sounder Control Unit and the loop-powered VAD may also be synchronised. This method of synchronisation depends on the design and configuration of the control panel. Further information should be sought from the panel manufacturer.
