TSM

OVERVIEW

TOXALERT’S Model TSM Stand-Alone Monitors are compact, eletro-chemical, cost effective gas monitors designed for fixed installation, continuous monitoring of commercial & industrial facilities. The TSM Series is a carbon monoxide (CO) sensor, nitrogen dioxide (NO2) sensor or a combination of both CO and NO2 sensors in one monitor. For design flexibility, there is an option to locate one of the sensors remote from the monitor. Each Stand-Alone Monitor is microprocessor based to ensure trouble free, long-term stability and has three (3) field adjustable stages of operation. Relay outputs for each stage are designed for fail-safe operation and fail to energize remote equipment such as ventilation fans and visual alarms.

The Model TSM is a self-contained monitor in an architecturally appealing ABS housing with indicators for power on, microprocessor running (malfunction), warning or fan stage energized, alarm stage and high alarm stage. Options available are an LCD display of gas concentration and audible alarm with silence. The audible alarm silence push-button temporarily silences the audible horn until the next alarm.
