Product Reflected Beam Smoke Detector and Engineering Specifications reflected beam smoke detector shall be a System Sensor model number BEAM200 detector shall be an addressable intelligent single ended reflected beam smoke detector shall connect with two wires to the fire alarm control panel signaling line circuit SLC The shall consist of a transmitter receiver unit and a reflector and shall on command from control panel send data to the panel representing the analog level of smoke density the obscuration reaches alarm thresholds chosen at the transmitter receiver unit or fire control panel the detector shall generate an alarm signal Complete blockage of the beam cause a trouble signal Slow changes in obscuration due to a build up of dirt or dust on the of the detector shall be compensated for by a microcontroller that continuously monitors the strength and periodically updates the alarm and trouble thresholds When the self circuit reaches its limit the detector shall generate a trouble signal indicating the for service detectors shall provide address setting means on the detector using rotary switches of the possibility of installation error systems that use binary jumpers or DIP switches to the detector address are not acceptable The detectors shall also store an internal identifying that the control panel shall use to identify the type of detector Systems that require a programmer to set the detector address including temporary connection at the panel are intensive and not acceptable Each detector occupies any one of at least 99 possible on the SLC loop It responds to regular polls from the system and reports its type and detector can have its sensitivity tested required per NFPA 72 2007 Edition Chapter 10 on Testing and Maintenance when installed connected to a compatible addressable fire control panel detectors shall provide a test means whereby they will simulate an alarm condition and report condition to the control panel Such a test may be initiated at the detector itself by activating switch or initiated remotely on command from the control panel There are three test methods test filter test switch or panel detectors shall provide three LEDs A red LED shall be for alarm a yellow LED shall indicate and a blinking green LED shall be for standby operation The panel shall control the of the red and green LEDs The local reset button is accessible by removing the outer trim ring The yellow LED shall blink in specific patterns to provide a diagnostic aid diagnosing the cause of a trouble signal It shall also blink the amount of drift that has been used at the conclusion of the test Trouble signals automatically upon removing the cause of trouble Red and yellow LEDs can be remotely connected to remote Alarm and Trouble outputs These outputs mimic the functions of the detector red yellow LEDs In addition to these indicators there shall be a dual digital display that reads 00 99 This display shall indicate the signal strength of the beam in alignment mode and shall the sensitivity setting of the detector in percent obscuration when setting the sensitivity of detector No additional equipment is needed for alignment of the beam 268 Smoke Detectors for Fire Alarm Signaling Systems Agency Standards CAN ULC S529 Smoke Detectors for Fire Alarm Systems 3230 3250 Smoke Actuated Detectors for Automatic Fire Alarm Signaling 2010
