Detector Tester Selector
Answer a few questions about the detectors you maintain and we will build a recommended bill of materials: test heads, access poles and consumables.
Product selection guide
Built around detector type, test method, access height, site constraints and common Solo/Testifire kit combinations.

Step 1
Select every type on the systems you maintain. This decides which test stimulus (smoke, heat or CO) your kit must produce.
Step 2
Each sensor in a multi-sensor detector needs its own test stimulus, so this determines whether your kit must also produce CO.
Step 3
Ajax EN54 smoke and heat detectors can only be functionally tested with the Testifire XTR2 fitted with the Ajax-approved AJAX-ADAP adaptor. No other tester is approved by Ajax.
Step 4
Standard point smoke testing is always included when smoke is selected. ASD systems using air-sampling pipework need a dedicated adaptor.
Step 5
Digital, per-detector test records are available through DT Connect, which requires the Testifire XTR2 connected tester.
Step 6
Clearing purges residual stimulus from the detector after a test, helping it reset quickly and avoiding nuisance re-alarms.
Step 7
The mains-powered heat tester needs safe power access and cable management on site. If that is not practical, choose a cordless route.
Step 8
If you already have them, you only need the cordless heat tester head. Otherwise the complete kit includes everything.
Step 9
Larger detectors, or detectors fitted with protective cages, may need the larger-cup dispenser. Compatibility should still be checked against your exact detector models.
Step 10
Some sites and HSE policies require non-flammable test aerosols. Capsule-based testers do not need this question because their capsules are non-flammable.
Step 11
Measured from the floor to the detector, in metres. We allow an assumed operator reach of 1.5 m when working out which access pole you need. Heights above 9 m are referred to our technical team for review.
Step 12
Our urban pole range packs down short for engineers travelling between city sites, including by public transport.
Step 13
A removal tool lets you take detectors down from height for replacement or maintenance. It is not a test head.
Step 14
Ajax detector heads require the Solo 230. The Solo 200 suits most standard, non-Ajax detector heads.

Recommended system
System layout
Please note that in this hardwired Grade D1 system, the smoke and heat alarms interlink through the wired connection, but the CO alarm operates as a standalone unit. This is fully compliant in all parts of the UK, as there is no requirement for CO alarms to be interlinked with the fire detection devices.

Before you continue
Adjust your system
Your recommended system already covers the essential areas of your property and meets UK domestic fire protection requirements. You can extend coverage or add additional features if needed.
Professional assessment
If you would prefer professional confirmation, arrange a fire risk assessment with a competent fire safety professional.
