Battery and brightness

• At least 2 hours of battery operation
• 90% of required illumination within 5 seconds of power failure
• HXS is rated 3 hours and runs up to 5 hrs

Testing

• Monthly functional test
• Annual full-duration test
• Results recorded in a register
• Automatic testing devices permitted — HXS runs them to IEC 62034

Sign design

• Internally illuminated signs — the approved type
• One uniform design per building
• Letters at least 125 mm, or a 125 × 125 mm graphical symbol
• Green and white, high contrast
• Running-man pictogram, minimum 125 × 125 mm, green on white; directional versions add escape-route arrows

Mounting

• 2 m to 2.5 m above floor level, at the base of the sign
• Directly above the exit doorway

Where this applies

• Licensed and registered premises — restaurants, cinemas, entertainment venues, karaoke, child care centres, converted schools

For contractors

• Registered Class 2 fire service installation contractor
• Completion certified on Form FS 251

Choosing a size

• 180 mm — standard doorways and corridors
• 270 mm — longer escape routes, directional
• 400 mm — maximum visibility, letter legends
• All sizes share the same IEC 62034 automatic testing

Common questions

• Exit sign height — 2 m to 2.5 m above floor level
• Exit sign size — 125 mm letters or a 125 × 125 mm pictogram minimum
• Exit sign colour — green and white, high contrast
• Bilingual lettering — English and Chinese, or an approved graphical symbol instead
• What is IEC 62034 — the international standard for automatic test systems for battery-powered emergency escape lighting; HXS tests itself to this standard
• Battery duration — at least 2 hours by law; HXS is rated 3 hours and runs up to 5
• Testing frequency — monthly functional test and annual duration test, results kept in a register
• Who can install — a registered Class 2 fire service installation contractor, completion certified on Form FS 251
• Existing buildings — mixed exit sign designs are acceptable, but one uniform type is recommended as signs are replaced
• LED lifespan — LED exit signs run for years with no lamp replacement; the battery is the only service item
• Route coverage — signs must mark every exit and every change of direction along the escape route
• Records — keep the test register ready for licensing inspections

After testing an emergency lighting unit, FSD requires the result to be logged. PPA/104(A) C.14(b): the annual full-duration test result must be entered in a register; monthly test results are recorded in the same log book.

The register follows BS 5266-1 (the standard referenced by FSD Circular 5/2021): Annex J defines the log book contents — installation details, equipment register, monthly and annual test results, faults and repairs; Annex M provides the model forms — inspection and test certificate, test record, fault action record.
