Mircom Photoelectric Smoke Sensor For Use With Control Panels

Mircom Photoelectric Smoke Sensor.

The MIX-2251APA require compatible addressable communications to function properly. Connect these sensors to listed-compatible control panels only.

General Description
Models MIX-2251APA, MIX-2251TAPA and MIX-2251TMAPA are plug-in type smoke sensors that combine a photoelectronic sensing chamber with addressable-analog communications. The sensors transmit an analog representation of smoke density over a communication line to a control panel. Rotary-decade switches are provided for setting the sensor’s address.
Two LEDs on the sensor are controlled by the panel to indicate sensor status. An output is provided for connection to an optional remote LED annunciator (P/N RA400ZA/RA100ZA). Models MIX-2251TAPA and MIX-2251TMAPA combine a photoelectronic sensing chamber and 135°F (57.2°C) fixed temperature heat detector.
