DC-9102E Conventional Photoelectric Smoke Detector is a new-generation product. With built-in microprocessor, the detector is highly fixed with reliable fire judging program, which make it stable and reliable performance. When the detector checks fire signal, it will send fire information to the control panel or addressable zone monitor unit by means of current changing. The detector keeps turning on the LED to indicate alarm state until it is reset. The detector is developed from sensing chamber by scattering theory. It has the ability to resist dust contamination and environmental light. The detector utilizes drift compensation algorithm: When the environment is changing, such as dust accumulation, humidity and temperature changing, the detector can figure out these drift variation to make up for sensitivity, thus the amount of smoke needed to generate an alarm remains constant, irrespective of environmental conditions. The principle diagram is shown as Fig. 1 

The Intelligent Auto-Aligning Beam Detector combines a transmitter/receiver in the same detector head with an automatic alignment motor. This combination with integrated addressability allows for quick and simple installation. The Intelligent Auto-Aligning Beam Detector automatically compensates for environmental effects on the beam signal, keeping the unit in the best possible working order. This is achieved through the combination of software (automatic gain control) and motorised realignment of the beam.• Loop Powered and compatible with XP95, Discovery and CoreProtocol* • Incorporates a bi directional short-circuit isolator • Automatic drift compensation • Automatic reset • Ground level Controller • Automatic alignment compensation for building movement • Laser assisted alignment for quick installation • Allows for two detector heads per controller • Up to 100m range • Pre-alarm threshold

DC-9105E is a conventional reflective beam detector, powered by 24V. with excellent built-in microprocessor, the detector can carry out system adjustment, drift compensation of ambient data, and judgment of fire and fault through fixed algorithm. The detector has an integral visible laser pointer and 2 bits digital tube. It is easy to install and align with the reflector，convenient for commissioning with indications of 2 bits digital tube displaying received light intensity. The sensitivity of the detector can be set through handheld programmer in field, suitable for various applications including large storage zones, shopping malls, fitness centers, gyms, exhibition halls, hotel lobbies and areas with complex ceilings.

The Intelligent Switch Monitor is designed to monitor the state of one or more single pole, volt-free contacts connected on a single pair of cables to report the status. It has a selectable status reporting delay making it suitable for monitoring flow switches. Refer to Table 1 for digital communications protocol compatibility and Table 2 for the Intelligent Switch Monitor operating modes. • Improved design for ease of wiring meaning faster installation • Contains controllable isolator * • Address range 1 - 254 * • Five pre-configured modes, including compatibility mode from XP95/Discovery to CoreProtocol systems * • Priority mode for fast response * • Configurable input styles *
