The ESL 500N series two- and four-wire conventional photoelectric smoke detectors bring together trusted technology and a full line of features to meet the demands of every type of application. The 500N offers sounder models in two- and four-wire applications, specifically
to meet residential code requirements. The 521NCSXT has the
additional benefit of low current draw which makes it compatible with a wide variety of control panels. The ESL 500N series also offers choices for optional auxiliary relays and isolated heat sensors, not available before in the ESL 500 series. ESL offers CleanMe®, dust compensation, field replaceable optical chambers, multiple criteria heat algorithms, and self-diagnostics features.
ESL 320A/350 Series alarms are single/multiple station photoelectric AC smoke alarms designed for use in residential occupancies, including hotels, motels, and dormitories. The 320A/350 Series is compatible with existing ESL 320 Series wiring and up to twelve units may be interconnected for tandem operation. When any unit in tandem senses smoke, all the units sound an alarm.
The ESL 320A/350 Series features a test/silence button on the front of the alarm that facilitates testing. The series continuously monitors its own sensitivity; and if the alarm falls out of sensitivity, ESL's proprietary field replaceable optical chamber enables quick and easy cleaning and maintenance. The series meets NFPA 72 field sensitivity requirements without the need for external meters.
The 350 Series provides a battery backup that offers up to 46 hours continuous protection in the event of a power outage. Other models provide auxiliary relay options.
All models are photoelectric alarms, which detect smoldering fire faster than the more common ionization alarms. Since smoldering fire is one of the most preva-lent types of residential fires, photoelectric alarms are essential in these applications.
Photoelectric smoke detector with multi-sensor for battery operation
In-built heat sensor (alarm triggered at approx. 60°C) and muting (for approx. 10 mins.) at the touch of a button
Stand-alone mode
Prevention sets fire to in a flat extra design.
The discrete and elegant bpîtier agrees with a modern architecture and is integrated into all the interiors. Setting in radio operator network intelligent on 868 MHz - without posing cables. For a maximum security since all the smoke detectors put in radio operator network start alarm and thus announce at once a possible appearance of smoke, even in a part located at the variation.
