Accessory code PB10 EN54 passive speaker for recessed installation in an Ø170 mm Blade R body. - 12W 8 ohm / 12W 100V / 6W 70V PB10: EN54 passive speaker for recessed installation in an Ø170 mm Blade R body. - 12W 8 ohm / 12W 100V / 6W 70V Technical description: Passive speaker for recessed installation in an Ø170 mm Blade R body. The Speaker can operate with traditional amplifiers with a constant impedance of 8 ohm or with 100/70 V line amplifiers for music and announcements (PA-public address system). Extruded aluminium and steel body with a painted mesh on the front. The speaker is CPR / EN54-24 certified which means it can be used on "Voice Alarm" evacuation systems outlined in the standard. 3" loudspeaker with a neodymium magnet for increased performance and lightness. Rated power: 12 W @ 8 ohm or 12 W @ 100 V (PA) frequency response: 115 Hz - 20,000 Hz, sensitivity: 82 dB SPL 1W @ 1 m. Dispersion angle 160° conical (1 kHz). Complete with ceramic terminal block and thermal fuse inside the body. Installation: Secured using 3 screws at the back of the Blade R device. Colour: White (01) | Black (04) Weight (Kg): 1.2 Mounting: ceiling surface Wiring: Complete with cable clamp and 90 cm long anti-flame cable and terminal block PH120 for connection. Red/black for 8 ohm connection, black/blue/brown for 100 V / 70 V line connections. 2 power selection (12W / 6W@100V or 6W / 3W@70V). Notes: In systems with traditional constant impedance amplifiers the low frequencies must be limited to less than 115 Hz by adjusting the source’s equalization controls (e.g. the amplifier bass knob).
