449CSTE - Smoke Detector W/Heat Sensor, Sounder & Status Relay Overview

The ESL 449/448 Series self-diagnostic, four-wire smoke detectorscontinually monitor their own sensitivity and operational status, andprovide a visual trouble indication if they drift out of sensitivity rangeor fail internal diagnostics. This unique, patented technology meetsNFPA 72 field sensitivity testing requirements without the need forexternal meters.Additional diagnostic information is activated by applying a magnetnear the detector's integral reed switch. This initiates aself-diagnostic routine and provides visual indication of sensitivitylevel, or if service is required.This series is easily cleaned by simply replacing ESL's proprietaryfield-replaceable optical chamber. All models are designed to reducefalse alarms from dust, insects, RFI, and external light.An integral combination rate-of-rise and fixed 135°F (57°C), 50-footrated, heat sensor is available with all ''T'' model detectors (seeselection guide), allowing latching of the alarm for either smoke orheat. The 449CSRH includes an isolated alarm

Product Features

• Connects to a hardwired security system for an incredible degree of fire protection
• Self-diagnosing feature alerts you if any maintenance is required
• Triggers a loud 85dB siren AND sends an alarm signal to your security system
• Activated by smoke or fast-rising temperatures

Buy GE Security 405-05 Polarity Reversal Module, 12/24VDC, 4-Wire Smoke Detectors Only. Enables Any Control Panel to Trip All ESL Sounder Smoke Detectors For Sale

GE Security 405-05 Polarity Reversal Module, 12/24VDC, 4-Wire Smoke Detectors Only. Enables Any Control Panel to Trip All ESL Sounder Smoke Detectors Overview

Polarity reversal modules are designed for use with smoke detectors that have built-in sounders. On alarm, the module disconnects the detector from its normal power supply and applies reverse polarity from the notification appliance circuit. Applying reverse polarity causes the sounders on detectors not in alarm to activate. The 405-05 module ship with double-sided adhesive.

Product Features

• Allows smoke detectors with sounders to activate simultaneously; for use with 4-wire smoke detectors only
• Mounts easily into control panel
• Operating Humidity: Minimum 0.0 % RH; Maximum 85.0 % RH
• Operating Temperature: Minimum 32.0 degree F; Maximum 120.0 degree F
• Operating Voltage: Minimum 12.0 V; Maximum 24.0 V

GE Security 521NCSXT Photoelectric 2-Wire Smoke Detector w/CleanMe, Heat Sensor and Sounder, 8.5 - 33 VDC. Smart Dual Fixed/Rate of Rise Heat Sensors. Overview

The 521 Series self-diagnostic, two-wire smoke detectors are the industry's first conventional direct-wire smoke detectors with analog features such as remote maintenance/trouble reporting (CleanMe), drift compensation, and multi-criteria detection. The 521 Series continually monitor their own sensitivity and operational status, and provide a visual and remote trouble condition if they drift out of the sensitivity range or fail internal diagnostics. This meets NFPA 72 field sensitivity testing requirements without the need for external meters. The 521 has a unique feature enabling it to send a signal (CleanMe) to the 505 module (sold separately) when it has drifted outside of its UL Listed sensitivity range or has failed its internal diagnostics test. The 505 is an interface module that will signal a 24V panel via relays when the 521 is dirty. Several 12V and 24V control panels have the CleanMe software built in, eliminating the need for the 505 module. When CleanMe is not desired, simply leave the switch on the 521 off and it will work as a normal two wire detector. CleanMe allows the installer time to schedule a service call and avoid a false alarm. Time between cleaning detectors is dramatically increased because of the 521's built-in drift compensation. This feature, usually only available in analog systems, allows the detector to automatically adjust its sensitivity over time as it becomes dirty, increasing the life of the detector. And when the 521 has told you that cleaning is necessary, it's literally a snap with ESL's patented field replaceable optical chamber.

Product Features

• Intelligent self-diagnostics
• Heat sensor is available with all T model detectors
• 85dB built-in sounder alarms when smoke is detected or when power wiring polarity is reversed.
• CleanMe remote maintenance reporting reduces false alarms
• Smart dual fixed/rate of rise heat works with photo chamber to catch fires faster
