System Sensor RTS151KEY Remote Test Switch Overview
The System Sensor RTS151KEY Remote Test Switch allows building personnel to conveniently test compatible duct smoke detectors from a remote location. Designed for safety and efficiency, it eliminates the need to access difficult or hazardous areas where detectors are mounted. This feature ensures compliance with routine fire safety testing requirements while saving time and reducing operational risks.
The System Sensor RTS151KEY Remote Test and Reset Station provides convenient remote testing and resetting for compatible duct smoke detectors. It features a key-operated control switch and a visual LED indicator. In addition, its compact wall-mounted design allows technicians to access important detector functions without reaching the duct detector housing.
Key-Operated Remote Test and Reset
The System Sensor RTS151KEY allows authorized personnel to initiate supported test and reset functions from a remote location.
The station uses a key-operated switch rather than a standard push button. Therefore, it helps restrict access to personnel who have the appropriate key.
This design makes the device useful for commercial and institutional fire alarm installations that require controlled testing access.
Convenient Duct Detector Testing
Duct smoke detectors often sit above suspended ceilings or inside mechanical areas. Consequently, direct access can require additional time and equipment.
A remote test station provides a more accessible control point. Technicians can initiate the supported test function without opening the duct detector housing.
As a result, the station can simplify routine maintenance and inspection procedures.
LED Status Indication
The remote station includes an LED indicator that provides visual information from the connected detector.
During supported alarm or test conditions, the indicator helps technicians identify the detector’s status.
In addition, the LED provides a convenient visual reference when performing inspection and maintenance.
The exact indicator behavior depends on the connected duct detector and wiring configuration.

Compatible Duct Smoke Detectors
The System Sensor RTS151KEY supports selected System Sensor duct smoke detector models and compatible OEM versions.
Common applications include compatible DNR and DNRW duct detector housings. However, technicians must confirm the exact detector model and remote test wiring requirements.
Not every duct detector supports the same remote accessories. Therefore, installers should review the manufacturer’s compatibility documentation before installation.
Compact Wall-Mount Design
The station uses a compact wall plate that mounts to a standard single-gang electrical box.
Its accessible location allows maintenance personnel to perform remote testing without reaching the detector itself.
Furthermore, the wall-mounted design helps provide a neat installation in mechanical rooms, corridors, and other approved service locations.
Typical Fire Alarm Applications
This remote test and reset station supports many commercial and institutional HVAC fire alarm applications.
For example, technicians may use it in office buildings, schools, hospitals, hotels, warehouses, shopping centers, and industrial facilities.
It is particularly useful when duct smoke detectors sit in difficult-to-access locations.
Maintenance and Inspection
Remote testing can simplify maintenance procedures. However, the station does not replace every inspection or functional test required for a duct smoke detector.
Technicians should still inspect the detector housing, sampling tube, airflow conditions, and sensing chamber according to the manufacturer’s instructions.
In addition, they should verify proper alarm and reset operation during system testing.
Installation and Compatibility
Before installation, confirm the connected duct detector model, wiring requirements, and electrical compatibility.
Also, verify the remote station mounting location and required access for authorized personnel.
Qualified fire alarm professionals should install and test the station. Furthermore, technicians should follow System Sensor instructions and applicable fire alarm codes.
Overall, this System Sensor remote test station provides convenient and controlled access to duct smoke detector testing functions. Its keyed switch, LED indication, compact design, and remote reset capability make it a practical accessory for compatible HVAC fire alarm systems.
