• Loop-powered XP95/Discovery addressable sounder base.
• Two selectable tones and stepped/adjustable volume settings for flexible site use.
• Fits XPERT family mounting bases and accepts appropriate addressing/configuration cards.
• Simple installation for contractors and retrofit applications; typical use in commercial and residential fire alarm systems.

Key benefits

• Local audible alerting integrated into the detector base — reduces wiring and installation time compared to separate sounders.
• Selectable tone and volume allow compliance with site acoustic requirements.
• Addressable operation provides individual and group control from the fire panel.

Compliance & Safety
Meets relevant sounder approvals for Apollo sounder-base variants (e.g. EN54-3). Installation must be carried out by a qualified engineer in accordance with local fire and electrical regulations. Check the official Apollo datasheet for detailed wiring, current draw at each volume setting and recommended head spacing.
