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)

STMicroelectronics Analog ICs
GYROSCOPES
ST’s complete family of single-axis (yaw) and two-axis (pitch-and-roll, pitch-and-yaw) MEMS gyroscopes offers the industry’s widest full-scale range, from 30 to 6000°/s.
The innovatively designed sensors can provide two separate outputs for each axis at the same time – an unamplified output value for general detection of angular motion and a 4x amplification for high-resolution measurements that enhances design flexibility and the user experience.
