How to choose
Start with the system. The Soteria and Discovery base sounders, the Intelligent Open-Area range and the Discovery and XP95 sounders and sounder bases are addressable loop devices; the Intelligent range works natively across XP95, Discovery and CoreProtocol, and many Discovery and XP95 devices are listed for all three, so check the exact model against your panel. The Conventional Open-Area sounders, the Sonos Pulse conventional VADs and the 6 inch fire bell are for conventional sounder circuits, and the Conventional I.S. Open-Area Sounder is for intrinsically safe signalling.
Then choose how the device warns people. A sounder gives an audible alarm. A VID (visual indicator device) adds a flashing beacon as a supplementary signal, while a VAD (visual alarm device) is a flashing light certified to EN 54-23 for places where sounders may not be heard, such as noisy workshops and machine rooms or areas used by deaf or hearing impaired people. A sounder VAD combines both. EN 54-3 is the European standard for fire alarm sounders.
EN 54-23 VADs carry a category and a coverage code. C means ceiling mounted, W wall mounted, and O is the open category where the maker defines the coverage. In a code such as W-2.4-6 or C-3-15, the first number is the maximum mounting height in metres and the second is the size of the area covered in metres: the width of a square room for W, the diameter of the covered area for C. The Apollo VADs here include W-2.4-6, W-3.1-10, W-3.1-11.3, C-3-8 and C-3-15 models.
Finally check sound output, tones and mounting. The XP95 open-area sounders offer 92 or 100 dB(A), the Conventional Open-Area Sounder up to 106 dB(A) with 32 tones, and the XP95 sounder bases volume ranges of 55 to 75 or 75 to 91 dB(A). Isolating versions include a short circuit isolator, and IP65 models suit damp or dusty areas. FPS supplies, installs and maintains Apollo sounders and VADs in Bhopal and across Madhya Pradesh.
Frequently asked questions
What is the difference between a sounder, a VID and a VAD?
A sounder gives an audible fire alarm. A VID is a visual indicator used as a supplementary signal alongside the required sounders and VADs, while a VAD is a visual alarm device certified to EN 54-23 for places where a sounder may not be heard.
What do VAD codes like W-3.1-10 or C-3-15 mean?
They are EN 54-23 coverage codes. The letter is the category (W for wall, C for ceiling), the first number is the maximum mounting height in metres, and the second is the width of the square room (W) or the diameter of the covered area (C) in metres.
What is a base sounder?
Base sounders and sounder bases mount on Apollo detector bases at ceiling positions. The Soteria and Discovery base sounders connect directly to an XPERT base and offer 15 tone pairs and 7 volume levels, while the XP95 and Discovery sounder bases have an integral mounting base.
Can the tones be used for other messages?
On some models, yes. On the Discovery Open-Area Sounder VID the tones can be used for purposes other than fire warning, which Apollo notes suits schools, and the Discovery Open-Area Voice Sounder has four pre-set message pairs for clear instructions.
Which Apollo sounder suits a hazardous area?
The Conventional I.S. Open-Area Sounder. It is ATEX and IECEx certified, GOST-R certified for Zone 0 and FM certified for Class I Division 1 and Class I Zone 0, and it is IP65 rated.
Does FPS supply and install Apollo sounders in Bhopal?
Yes. FPS is an authorised Apollo distributor and supplies, installs and maintains Apollo sounders, beacons and VADs in Bhopal and across Madhya Pradesh. Prices are on request: call or WhatsApp +91 92440 89060.
