wall type co sensor dry contact output

The Smoke Detector with builtin relay utilizes a photoelectric sensing method and is designed for use in commercial and residential applications. The device requires hardwired 120VAC 60Hz power. The detector features two sets of dry alarm contacts: one formA SPST and one formC SPDT. The detector has tandem interconnect capability allowing up to 6 devices to be connected together.

20140807· A dry contact output can also be referred to as a voltfree contact, relay, or contact output. It is nothing more that a standalone set of two contacts with no voltage, current, or anything else impressed across the contact set. A dry contact essentially looks like an electrical switch. There are two states for a dry contact: open and closed. On a normally open dry contact output, when the ...

Our wireless dry contact sensors monitor the status of any equipment that has a voltfree, dry contact output, such as UPS status, security systems, fire alarms or air conditioning units. The small, energy harvesting devices use ultralow power wireless and batteryless technology, making them easy to install and very low maintenance. As a trusted partner to some of the world’s leading ...

APPLICATION. DESIGN AND COMPATABILITY. The sensor is designed for indoor carbon dioxide concentration measurement and respective air capacity regulation through the control output signal to the fan. Air capacity control based on CO 2 concentration is an efficient energy saving solution. The sensor has two separate outputs: a normally opened dry ...

The BPD type of the TRANSLUX sensor family are low voltage daylight sensors designed to provide isolated dry contact with 010 V output for on/off switching or continuous dimming control. The BPD5xx series comes with typical on/off control or SmartDIM continuous dimming control. Line Voltage SmartDIM Occupancy Sensor. The LRD609SA series of the TRANSPIR sensor family are twoway IR remote ...

offers 2,392 dry contact sensors products. A wide variety of dry contact sensors options are available to you, such as theory, usage, and special features.

Models 500R, 1000R, and 2000R for wiring the dry contact output from LOS sensors to the QSEIO ( 7 wire Occ Sensor with photocell) Note: When used with a GRAFIK EyeR QS standalone system in partitioned areas, each occupancy sensor input will only control the individual area. Changes in occupancy sensor state will not control adjacent ...

Breathing Detecting ceiling mounted occupancy sensor Dry Contact Output MSA021D RC ...Occupancy / Vacancy Sensor of Breathing Detecting, Flush Mounted, 1224Vdc, Dry Contact Output MSA021D RC 1. Innovative patent energysaving switch, control lights ONOFF automatically.

7 – open/close alert (door sensor); 8 – CO alarm; 9 – CO2 alarm; 10 – on/off report (dry contact switch/sensor); 11 – garage door mode for the relay (momentary contact) and door sensor type for the input (use with wired analog door/window sensors and garage gate openers). Default: 2. NOTE: Press and hold the ZWave button for 5 seconds to change to garage mode manually. IMPORTANT: If ...

sensor will begin reading the CO2 level, output the correct analog signal and display the value on the LCD. Output Signal The CO2 output is scaled such that 420 mA (or 05/010 Vdc) equals 0 to Out_High. Depending on the model, the factory default is either 02000 ppm (CDD4A) or 020,000 ppm (CDD4B). Out_High can be changed in the Setup Menu and the output is scaled accordingly. If using ...

20150128· Dry contact sensors are userdefinable and can be used to detect many different inputs such as UPS status, security systems, air conditioning status. These generalpurpose switches can be either input or output. When used as an output it can source up to 20 amps. You can select the output voltage by setting the Output Level to a Low or a High.
