Notifier LPX-751L View Laser Smoke Detector

Model LPX-751 is a plug-in smoke sensor that combines a laser photoelectronic sensing chamber with addressable analog communications. The use of a laser diode provides substantial improvements in signal-to-noise ratio compared to a traditional LED light source. The sensor transmits an analog representation of smoke density over a communication line to a control panel. Rotary decade switches are provided for setting the sensor address (see figure 2). The sensor has two multicolored LEDs controlled by the panel to indicate sensor status. Flashing green indicates normal operation and steady red indicates alarm, prealarm, or trouble. An output is provided for connection to an optional remote LED annunciator (Model RA400Z). Features / Specifications Advanced laser light source and patented optical design. Sleek low-profile housing (1.66″/42.164 mm height). Analog addressable communications protocol provides extremely reliable operation. Sensitivity to 0.03%/foot. Rotary decade switches all
