York 025-35787-008 SPST 20' FIX RESET SENSOR

SPST 20' FIX RESET SENSOR

The SPST 20' FIX RESET SENSOR is a mechanical control device for use in air-side HVAC applications where the energy source is located in one area and the thermal load is located some distance away. The SPST 20' FIX RESET SENSOR provides local on/off functionality while restoring the system to its original state after each operation. It also features an LED indicator that communicates operational conditions, visual alarm capability for added safety, and allows room for custom labeling

The York 025-35787-008 SPST 20' FIX RESET SENSOR is one of our best sellers in ceiling fans.

The York SPST 20' Fixed-Reset Sensor, an easy to install and economical security sensor, fits the standard four inch by four inch junction box standard in most homes and businesses. It is also compatible with many alarm panels.

This general purpose sensor is a compensating snap-action switch. It has a SPST (Single Pole, Single Throw) on-off switch, set point of 20' and a reset function. This sensor is commonly used on misting systems.

The Adams Rite FRN20-I Fixture Sensor activates the opener when the door is moving in the proper direction and deactivates after a specified time limit when door has ceased to move. This door check provides positive assurance that a user or object has cleared the opening when the door closes.

Here is a perfect solution for a security system. The automatic reset feature ensures that even if a burglar triggers a sensor, the signal will automatically reset after 20 seconds to allow an intruder to leave the protected area without setting off other sensors or alarm systems. The compact size can be mounted in tight areas.

Control device - the type of valve controller used with this is known as a 'single pole single throw' or SPST. it is, in effect, a tiny variable resistor that passes more current when it is in the 'on' position than when it is in the 'off' position, when you change this switch from 'on' to 'off' (normally by moving it up and down) air flows freely through the actuator of your valve; if you move it down to 'off', however, there will be no contact between contacts 1 and 3 (fig. A below), allowing air to pass between

The 20-Ft. Mini Sensor provides convenient, programmable control of electric doors and gates. Built-in diagnostics help troubleshoot problems and pinpoint trouble spots, and rugged construction ensures long life and dependability.

Simply plug your unit into an AC outlet and the ultra-sensitive photoeyes will begin searching for daylight. No programming is required, just sit back and enjoy the comfort of knowing your unit is on guard to meet the changing light conditions. The photoeye then resets itself to guard against interference from UV light that can affect performance. For added security, diodes are provided to help protect against lightning strikes.

The OMRON YR535 Series offers the ideal sensor for most HVACR applications, due to its high level of performance and exceptional value. The activation range of the YR534 is up to 150°F (66°C), with a 20 second reset time. Detects burner off, burner on, and base AC voltage input conditions. The digital last setting memory provides ease in installations requiring multiple settings.

In the event of a fire, there is a possibility that the fire sprinkler heads will be damaged. This could lead to water leaking from leaking heads or the ability to pressurize the pipes leading to a fire sprinkler system being unavailable to provide water. In an effort to address this concern, a bypass sensor has been developed. This bypass sensor is a non-mechanical device which will accurately detect if sprinkler heads have been broken and unable to function, and then provide a method for door operators and other appropriate equipment to be reset.

A safety sensor designed to trip a circuit with a solenoid valve in the event it is opened.
