RZ037-DRY Ceiling Mount PIR Occupancy Sensor with Dry Contact Relay
RZ037-DRY
RZ037-DRY is a ceiling-mounted PIR occupancy sensor with an isolated dry-contact relay output for EMS, HVAC, and building control inputs.
It accepts 12/24VDC or 12/24VAC power and provides COM, NO, and NC relay contacts so a control system can receive occupancy status without the sensor directly switching line-voltage loads.
- Isolated dry-contact relay output with COM, NO, and NC contacts
- Relay contacts rated for 30VDC max and 1A max
- 360-degree PIR occupancy detection from a ceiling position
- Adjustable time delay, Lux level, and high/low sensitivity
- Designed for low-voltage control-system wiring, not high-voltage load switching

Dry-Contact Occupancy Sensing For Control Systems
The RZ037-DRY adapts the RZ037 ceiling PIR sensor format for low-voltage control systems that need an occupancy signal instead of a directly switched lighting load.
Its isolated relay provides Common, Normally Open, and Normally Closed contacts, making it suitable for EMS, HVAC, and building control inputs where the controller decides what action follows occupancy detection.

Connect Occupancy Sensing To Building Controls
Use the dry-contact output when a control panel, HVAC controller, or energy management input needs to know whether a space is occupied without placing the sensor in the main load circuit.
Installers can choose the NO or NC contact logic according to the receiving system, then tune the time delay, Lux level, and PIR sensitivity from the sensor body after wiring.
Características, ventajas y especificaciones
RZ037-DRY combines ceiling PIR occupancy detection, 12/24V AC/DC power, and isolated COM/NO/NC contacts so installers can verify coverage, relay logic, and setup values before ordering.

Características y ventajas
- Isolated dry-contact relay: COM, NO, and NC outputs support control-system inputs instead of direct line-voltage load switching.
- 12/24V AC/DC supply: The sensor can be powered from 12/24VDC or 12/24VAC low-voltage control power.
- 360-degree PIR detection: Ceiling-mounted passive infrared sensing covers occupancy around the sensor position.
- Adjustable time delay: Select 15 seconds through 30 minutes to match testing, passageway, restroom, or work-area behavior.
- Selectable Lux control: Off, 15 Lux, 25 Lux, and 35 Lux settings let installers decide when ambient light should hold the relay off.
- High/low sensitivity: The sensor can be tuned for the expected movement pattern and room conditions.
- Clear wire identification: Red and black provide input power, while green, orange, and yellow provide NC, COM, and NO relay wiring.

PREGUNTAS FRECUENTES
What makes RZ037-DRY different from the line-voltage RZ037 models?
RZ037-DRY provides an isolated dry-contact relay output for a control system input. It is not specified as a direct line-voltage lighting load switch like the high-voltage RZ037 variants.
What power supply does RZ037-DRY need?
The manual specifies 12/24VDC or 12/24VAC input power. Red is IN+ and black is IN- in the supplied wiring diagram.
Which dry-contact wires are available?
The relay output provides green for Normally Closed, orange for Common, and yellow for Normally Open. Choose NO or NC logic according to the receiving EMS, HVAC, or building control input.
Can this sensor be used with EMS or HVAC systems?
Yes. The product description in the manual identifies EMS and HVAC systems as target integrations, with occupancy communicated through the internal isolated relay dry contact.
What coverage should installers expect?
The manual specifies 360-degree detection with an 8-12m detection diameter when ambient temperature is below 27C, and a recommended installation height of 2.5-3.5m.
Which setup values can be adjusted?
Installers can adjust time delay, light sensor level, and sensitivity. Time delay options range from 15 seconds to 30 minutes, Lux options include Off, 15Lux, 25Lux, and 35Lux, and sensitivity can be set to High or Low.
Why might the sensor not trigger immediately after power is restored?
The manual notes that when power is first turned on or restored, the sensor will not automatically control the load for the first one minute.
