Description The Gamewell-FCI Velociti™ Series, ABD-2F and addressable projected beam smoke sensor is uniquely suited to sense smoke in hostile environments or open areas with high ceilings where spot-type sensors are unsuitable or difficult to install and maintain. It is intended for use in the signaling line circuits with the E3 Series® ILI-MB-E3 and ILI-S-E3 (Velociti mode only). The ABD-2F consists of a combination transmitter/receiver unit and a reflector. When smoke enters the path between the unit and the reflector, it causes a reduction in the signal, and when the smoke level reaches the predetermined threshold, an alarm results.
Features • Single-ended, reflective design • Six (6), user-selectable sensitivity levels • 16 to 328 foot (4.9 to 99.9 m) detection range • Compatible with the E3 Series® ILI-MB-E3 and ILI-S-E3 • Integral sensitivity test feature (ABD-2SF) • Digital display - no special tools required • User-friendly alignment procedure • Integral automatic gain control compensates for signal deterioration from dust build-up • Remote test station (optional)

Outline This AUDIO IC was developed for notebook PCs and allows major reduction of amp circuit board area. (To conform to PC98, includes built-in speaker drive amp, headphone amp, line amp. stereo/monaural switching, DC voltage control electronic volume, watchdog, logic control function.)
Features (1) Speaker amp: Stereo BTL output 0.7W (when VCC = 5.0V, RL = 8Ω) (2) Electronic volume control (-60 ~ +20dB). THD = 0.5% (when POUT = 300mW, RL = 8Ω) THD1 = 0.5% (when VOUT = 100mVrms, RL = 16Ω) THD2 = 0.1% (when VOUT = 1VmVrms, RL = 10kΩ) (4) Line amp: Mixes 4 inputs ( 2ch signals and outputs on 3 outputs ( 2ch. Stereo/monaural switching possible on one line. THD = 0.1% (when VOUT = 1Vrms, RL = 10kΩ) (5) Microphone amp: Switch pin selects 1 of 4 inputs (6) Logic control: Speaker, headphone and line amp (including microphone amp and mix amp) logic controllable. Current consumption 300µA during power save mode.
The KA2206B is a monolithic intergrated circuit consisting of a 2-channel power amplifier. It is suitable for stereo and bridge amplifier application of radio cassette tape recorder.
FEATURES • High output power Stereo : PO = 2.3W(Typ) at VCC = 9V, RL = 4Ω. Bridge : PO = 4.7W (Typ) at VCC = 9V, RL = 8Ω • Low switching distortion at high frequency. • Small shock noise at the time of power on/off due to a built-in muting circuit • Good ripple rejection due to a built-in ripple filter. • Good channel separation. • Soft tone at the time of output saturation. • Closed loop voltage gain fixed 45dB (Bridge : 51dB) but availability with external resistor added. • Minimum number of external parts required. • Easy to design radiator fin.
