Overview
The FLv9 Slim keeps the premium Denler unlock stack — 3D face recognition, fingerprint/palm, camera, WiFi, Alexa, waterproofing and RF remote — in a slimmer chassis. That matters on doors with limited reveal or where a bulky lock body would look out of place. Perth apartments and modern timber doors with narrow stiles are common use cases. Enquire so we can verify thickness and strike clearance before install.
A closer look at the Denler FLv9 Slim — unlock methods, app control, security behaviour and what we check before a Perth install.

- Optional auto-lock with a door-left-open alert
- Anti-peep PIN — type extra digits before and after your real code to shield it from onlookers
- Emergency power — if the battery runs low while you are away, top up with a power bank or use the mechanical key. Note: emergency charging only works with the battery fitted; if the pack is removed, use the mechanical key.
- Low-battery alerts on the lock and app
- Lost-card cancel — remove users from the lock easily
Compatibility & install notes
- Door thickness — typically 35 mm minimum (confirm on quote for your Perth door)
- Single doors: compatible. Double doors: compatible with a tower bolt or secondary latch on the inactive leaf
- Wi-Fi models need 2.4 GHz Wi-Fi on your router
- Mount height matters: the camera should sit around chest height so face recognition works reliably.
- The door must be hung and aligned before fitting — we cannot set the lock true to the frame without the door in place.
Warranty
- Up to 5-year warranty on electrical and mortise parts against manufacturing defects (battery cover is shorter — typically 1 year). Confirmed on your Perth quote.
- If something goes wrong, contact us with a short video and we will arrange parts support through Denler.
Security design
It features an IP65 waterproof rating so exposed outdoor entries cope better with rain and coastal air. Live video intercom lets you see who is at the door and speak with visitors before unlocking.
App control
Denler FLv9 Slim connects over Wi-Fi so you can monitor the door remotely, receive notifications, and manage access for family, guests or trades. Useful when you are at work, travelling, or letting trades in — check the door and manage access from your phone.
Door & warranty notes for Perth installs
Slim body helps on tighter reveals; still confirm 35–100 mm thickness range.
Up to 5 years on the lock (excluding physical damage); battery cover confirmed on quote.
