ASD-LS Description Analog Addressable Laser Smoke Sensor The Gamewell-FCI, Model ASD-LS, is a low profile laser smoke sensor that adds another new dimension to analog addressable fire detection. It incorporates laser smoke detection technology that provides unsurpassed sensitivity and response to maximize detection. This feature makes the sensor ultra-sensitive to smoke, as much as 100 times more sensitive than conventional photo-electric smoke detection technology. An innovative laser diode and precision optics design combine with an array of integral software tools to allow the sensor to quickly identify the fire. The sensor can swiftly sense smoldering fires, but yet can sense the smallest particles of combustion, providing a faster response to flaming fires. The early warning capability of the ASD-LS is comparable to that of Aspiration Technology, while unlike Aspirating Systems, the ASD-LS can pin-point the location of the fire. The sensor is continually monitored to measure any change in its sensitivity due to the environment (dirt, temperature, transient smoke, humidity, etc.). Patented algorithms distinguish between particles of dust and smoke. The focused beam of the laser light source minimizes reflection from accumulated dust in the optical chamber, effectively minimizing problems caused by dust build-up. The software performs its own independent analysis of the sensor signal. This analysis includes dust spike rejection, drift compensation, smoothing, multi-sensor, pre-alarm decision and alarm decision. In the event of spikes in the signal, the sensor will check the output of adjacent sensors for any appreciable signal to determine if the spike is caused by a fast flaming fire. The sensor is a plug-in construction and is directly interchangeable in the same base with the Gamewell-FCI, ASD/ATD/Acclimate Series low-profile sensors. A wide variety of bases, with sounder, relay, etc. is available. The Remote LED annunciator capability is also available as an optional accessory. ASD-LS Features • Compatible with Gamewell-FCI Analog Addressable Control Panels. • Operates in the Velociti® or CLIP mode. • High Sensitivity for both smoldering and fast flaming fires. • Includes patented algorithms that ignore transient smoke and dust particles. • Provides low profile construction and an easy plug-in of the head to base. • Offers the following built-in features: - Signal processing - Tamper-resistant - Test switch • Supports a remote test feature (originating from the panel). The ASD-LS sensor is Listed for use inside ducts up to a velocity of 4,000 FPM. • 360° view angle of dual alarm LEDs. An optional isolator base, Model B224BI, is also available. Installation of two of these isolator bases allows Style 7 operation for sensors located electrically between the bases. • Maximum air velocity 4,000 FPM. • Optional bases for auxiliary functions.

Installation Specifications Place the sensor into the sensor base. Turn the sensor clockwise until the sensor locks into place. Sensitivity: Operating Voltage: Standby Current: Alarm Current (max.): Operating/Installation Temperature: Operating Humidity: To use the tamper-proof feature, break the smaller tab on the base as shown in the installation instructions. Install the sensor. To remove the sensor from the base when using the tamper-proof feature, insert the blade of a small screwdriver into the hole on the side of the base and push the plastic lever away from the detector head. This will allow the sensor to be rotated counterclockwise for removal. NOTE: When you use the tamper-proof feature, remove the decorative ring before removing the head. For information on spacing, the location of the sensors and other guidelines, refer to NFPA72, Chapter 5-3 “Smoke Sensing Fire Detectors.” Dimensions: Weight: .02 - 2.0%/ft. 15-32 VDC .00033 amp @ 24 VDC .0065 amp @ 24 VDC 32° to 100° F (0° to 38° C) 10% to 93% relative humidity (non-condensing) 1.7” (4.3 cm) height 4.1” (10.4 cm) installed in the B501 base 6.1” (15.5 cm) installed in the B210LP base 5 oz. (142 gm.) Ordering Information Testing Sensors may be tested locally in the following ways: A. Place a test magnet against the sensor housing per the instructions. The sensor should go into alarm within 30 seconds. B. Aerosol Generator - The Gemini Model 501 aerosol generator may be used to perform a Functional Test. This test should be performed immediately following the Magnet Test. The Magnet test initiates an approximately ten minute period when the detector's signal processing software routines are not active. Failure to first perform the Magnet Test will introduce a time delay before the detector alarms. Follow instructions in the Generator Instruction Manual. Maintenance Cleaning programs should be adapted to the individual environment in conformance with the National Fire Alarm Code, NFPA, 72. We recommend, at the least, an annual cleaning of the unit. The sensor screen and cover assembly can be removed, revealing the sensing chamber. A vacuum cleaner can be used to remove the dust from the screen, cover and sensing chamber. For the complete procedure, refer to the Installation and Maintenance Instructions furnished with each sensor.
