Combined smoke and heat testing
Portable combined testers for functional response checks of compatible smoke and heat detectors during commissioning, scheduled inspection and maintenance.
The blue product shown is the metal A119-YWS01 configuration supplied in the current product image.
Verified product configurations
A119-YW is the combined smoke-and-heat family. The supplied manuals identify two materially different configurations; their electrical and mechanical data must not be mixed.
The configuration represented by the current blue product image.
A separate black configuration documented in the newer YW02 manual.
Configuration control: confirm the full model suffix, working height, battery, pole, accessories and manual revision on the quotation. The YWS01 and YW02 values are not interchangeable.

Operating sequence
Use only after reading the exact supplied manual and the detector manufacturer's test instructions.
Confirm battery charge, approved smoke fluid, detector compatibility, pole connection and a secure work area.
Choose smoke, heated-air or air-blow mode. Indicator colors identify the selected and active state.
Bring the infrared sensor into the trigger area, apply the stimulus, verify detector response and record the result.
Safety information
During smoke operation, keep the head upward and do not block the air inlet. Incorrect orientation can dry-burn and damage the heating components.
Maintain sufficient fluid and use the manufacturer-matched product. Do not operate near flammable gas or in strong direct sunlight.
Do not touch the high-temperature area during heat testing. Allow the unit to cool and keep it dry after use.
Check the tester head, extension-pole joints and battery state before raising the tool to ceiling level.
A functional response test does not replace detector calibration, laboratory conformity testing, system commissioning or the complete inspection procedure required by the site or authority.
Standard / Pro / Max
| YWS01 version | Battery | Smoke tests | Approx. heating rate | Pole | Color |
|---|---|---|---|---|---|
| Standard | 7.4 V / 3000 mAh | >300 | 1°C/s | 3 m | Red |
| Pro | 7.4 V / 3200 mAh | >350 | 1.5°C/s | 3 m | Blue |
| Max | 7.4 V / 3500 mAh | >400 | 2°C/s | 4 m | Gold |

A119-YW questions
These answers define the product family and the limits of the available documents.
The A119-YW is a Wanlin product family combining smoke simulation and heated-air functions for functional response checks of compatible smoke and heat detectors.
A119-YWS01 is the aviation-aluminum configuration with a 7.4 V battery platform. A119-YW02 is a separate flame-retardant ABS configuration using a 3.7 V battery platform. Their specifications must not be mixed.
The supplied YWS01 manual documents 3 m Standard and Pro poles and a 4 m Max pole. The YW02 manual documents a 58 cm telescopic pole extending to 3 m.
No. It provides a functional response check and does not replace calibration, laboratory conformity testing, system commissioning or the complete inspection procedure required for the site.
Use the manual matching the full supplied suffix, housing, battery and pole configuration. Confirm the exact model and current document revision on the quotation.
