Notifier LPX-751L View Laser Smoke Detector TC830E1004 Model 5251RB is a rate-of-riseModel 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).
