Summary
The Apollo Category W Loop Powered VAD (55000-741, 55000-744) is a local area visual alarm device for indoor spaces where sounders alone won’t cut it, think workshops, machine rooms or any area where deaf or hearing-impaired occupants need visible warning. What sets it apart on site is that it’s entirely loop powered, so you’re not running a separate power supply cable alongside the fire loop.
View full overview Show less
That means one less cable run, one less power calculation and one less thing to fail during commissioning. It also keeps your design simpler when you’re adding VADs to an existing XP95, Discovery or Soteria loop, since the device draws its power directly from the loop itself.
On the loop, the device also synchronises its flash with other Apollo Protocol VADs, so you don’t end up with a room full of lights flashing out of step with each other. Fit it to an XPERT 7 or XPERT 8 mounting base, address it via the XPERT card, and it’s ready to work alongside your existing Apollo-protocol devices.
Features
- Loop powered design – draws power directly from the fire loop, removing the need for a separate power supply or extra cable run
- Synchronised flash rates – flashes in step with other Apollo Protocol VADs on the same loop, avoiding a disorienting mix of flash timings
- Fault signal on LED check failure – self-monitors the LED and reports a fault back to the panel, flagging issues before they’re found on a service call
- Wide coverage class W-2.4-6 – covers a 2.4 m x 6 m x 6 m (86.4 m³) cuboid volume, helping you plan device numbers per room
- Locking mechanism – a grub screw secures the VAD to its mounting base, reducing the risk of it working loose
- XP95, Discovery and CoreProtocol compatible – fits into existing Apollo loops without needing a different device family
- Red or white body options – 55000-741 (red) and 55000-744 (white) let you match the device to the decor or house style
- EN 54-23, CPR, LPCB and VdS approved

FAQ
No. It’s loop powered and runs directly from the fire loop at 17-28 V DC, so there’s no separate power cable to run to the device. It’s compatible with XP95, Discovery and CoreProtocol, and can be fitted to systems with Soteria devices on the loop. Exact behaviour is fire control panel dependent, so check your panel’s device list before specifying. The VAD fits any XPERT 7 or XPERT 8 mounting base, positioned with the XPERT card facing downwards for correct orientation and coverage. The IP rating achieved depends on the base used: IP54 with Part No. 45681-210, 45681-284 or SA5000-200, or IP55 with the Deckhead Mounting Box Part No. 45681-217. Addressing is done by coding the XPERT card fitted to the mounting base, the same method used across Apollo’s loop-powered device range. Yes, if it’s fitted to an Integrated Base Sounder, the sounder and VAD can be addressed and controlled independently. On an Ancillary Base Sounder (Part No. 45681-276), the sounder activation is instead controlled by the VAD. The two part numbers are identical in specification and coverage class (W-2.4-6); the only difference is body colour, with 55000-741 in red and 55000-744 in white.Does this VAD need its own power supply?
