The TX-6310-01-1 wireless carbon monoxide (CO) alarm monitors the levels of CO gas and gives early warning when potentially dangerous levels exist. It does not detect fire, smoke, or any other gas. If a dangerous concentration of CO is detected by patented and field-proven electrochemical sensor, an LED indicator illuminates and an internal siren is activated in temporal 4 pattern. The CO alarm also transmits an alarm signal to the control panel within 15 seconds of detecting dangerous concentration of CO gas. The control panel activates its internal siren and reports the alarm condition to the central monitoring station (if the system is monitored). The CO alarm also detects low battery, wall tamper, and sensor end-of-life. These trouble codes are transmitted to the control panel. The alarm automatically resets when CO is no longer detected.

The ESL 500 Series including the 521B and 521BXT self-diagnostic, two- wire photoelectric smoke detectors are the industry's first conventional direct-wire smoke detectors with analog features such as drift compensation, multi-criteria detection and remote maintenance/trouble reporting (CleanMe). The 500 Series continually monitor their own sensitivity and operational status, and provide a visual indication if they drift out of the sensitivity range or fail internal diagnostics. The 521 Series also can send a signal (CleanMe) to any compatible control panel, allowing the dealer/installer to schedule a service call and avoid a false alarm. UL, ULC CSFM Features: · CleanMe - remote maintenance reporting reduces false alarms (2-wire detectors only) · Smart dual fixed/rate of rise heats work with photo chamber to catch fires faster (521BXT) · Built-in drift compensation reduces false alarms · Field replaceable optical chamber makes servicing a snap · Small, low profile design blends in with any env
