Model selection
Choose Your A119 Detector Tester Model
The A119 family is built on one platform with three testing roles: combined smoke and heat testing, smoke-only testing, and heat-only testing. Select by the detector types on your sites, then confirm the exact suffix and accessories on the quotation.
Decision rules below use only the configurations documented in the supplied manuals.
Side-by-side comparison
Three models, one decision rule.
Pick the row that matches the detectors you maintain. Reach values are those documented in the supplied manuals; other pole options must be confirmed on the current quotation.
| Model | Smoke test | Heat test | Documented reach | Best for |
|---|---|---|---|---|
| A119-YW | Yes | Yes | YWS01: 3 m Standard / Pro, 4 m Max; YW02: up to 3 m | Mixed sites and contractors serving both detector types |
| A119-Y | Yes | No | Per current spec sheet | Smoke detector inspection programmes |
| A119-W | No | Yes | Per current spec sheet | Heat detector inspection programmes |
Smoke detector tester
Smoke-focused configuration for routine functional checks of compatible smoke detectors.
- Smoke simulation only
- Commissioning and periodic checks
- Specs confirmed per current spec sheet
Heat detector tester
Heated-air configuration for functional checks of compatible heat detectors.
- Heated-air test only
- No smoke medium required
- Specs confirmed per current spec sheet
Decision rules
Four rules cover most purchasing decisions.
1
Mixed detector portfolio
If your sites hold both smoke and heat detectors, choose A119-YW and carry one instrument instead of two.
2
Smoke-only portfolio
If you only service smoke detectors, A119-Y covers the functional check without paying for the heat function.
3
Heat-only portfolio
If you only service heat detectors, A119-W applies the heated-air stimulus without a smoke medium.
4
Working height
Match the pole to the ceiling height: documented reach is 3 m (Standard / Pro), 4 m (YWS01 Max) and up to 3 m (YW02). Confirm longer options on the quotation.
Configuration control: the YWS01 and YW02 values are not interchangeable. Confirm the full model suffix, working height, battery, pole and manual revision on the quotation.
Selection questions
Questions buyers ask before choosing.
These answers define the model family and the limits of the available documents.
Which model should I choose if I maintain both smoke and heat detectors?
Choose A119-YW. It is the combined configuration that performs both the smoke simulation test and the heated-air test, so one instrument covers a mixed detector portfolio. Confirm the exact suffix, pole and accessories on the quotation before ordering.
What is the difference between A119-YW, A119-Y and A119-W?
A119-YW tests smoke and heat detectors with one unit. A119-Y is the smoke-only configuration, and A119-W is the heated-air configuration for heat detector testing. Select by the detector types you maintain rather than by price alone.
How high can the A119 testers reach?
The supplied YWS01 manual documents a 3 m pole for the Standard and Pro versions and a 4 m pole for the Max version. The YW02 configuration documents a 58 cm telescopic pole extending to 3 m. Confirm the working height and pole option on the current quotation.
Can a smoke-only tester be converted into a combined tester later?
No. A119-Y, A119-W and A119-YW are separate configurations, and a smoke-only unit cannot be converted into a combined unit in the field. Choose the configuration that matches the detectors on your sites and confirm it on the quotation.
Where do I discuss OEM or distributor terms?
OEM and distributor enquiries are handled on the dedicated OEM page. Send your target market, annual quantity and customisation scope there, and we will confirm the model, documentation and branding options together.
