What this product is

Sitio KSR5424 is a 4.5W 110V LED emergency bulkhead designed for site lighting applications. The KSR installation sheet identifies it as a Sitio 110V IP65 Emergency Bulkhead in yellow, intended for connection to a 110V~50Hz supply. It sits in the Site Light Series and is positioned as a specialised site-lighting emergency fitting rather than a standard indoor-only emergency luminaire.

That distinction matters because temporary works and site environments often need fittings that are easier to identify, more suitable for harsher conditions and designed around 110V site power arrangements. KSR5424 addresses that brief by combining a site-friendly 110V format with emergency bulkhead functionality.

Verified technical details

• 4.5W LED
• 6500K light colour
• 110V~50Hz supply
• IP65 protection
• IK08 impact rating
• Class II construction
• 230 lumens on mains
• 267 lumens on battery
• Suitable for maintained or non-maintained emergency use
• Suitable for indoor or exterior use

The installation sheet also states a minimum 24-hour initial charge period before manual emergency testing and a 3-hour emergency duration expectation, with battery replacement advised if the fitting does not remain lit for the required period after charging. That gives useful context for commissioning and ongoing site use.

Where it fits best

KSR specifically references exit doors, fire escapes and corridors as suitable applications for this bulkhead. Those are exactly the kinds of positions where a compact emergency luminaire is often required on temporary sites and project setups. The bulkhead format makes sense where the priority is clear functional emergency lighting rather than decorative appearance or wide-area general illumination.

The fitting is also described as multi-functional because it can be wired as maintained or non-maintained. That helps specifiers keep the same core product across different emergency positions while selecting the correct operating mode during installation.

Protection and construction benefits

IP65 protection and IK08 impact resistance are useful features in this category because site lighting can face dirt, moisture and general knocks more often than permanent indoor fittings. KSR also confirms that the luminaire is Class II and does not require an earth, which keeps the electrical identity straightforward.

The supplied full legend set adds practical value as well. That means the product arrives with the signage element expected of an emergency bulkhead, making it easier to deploy correctly for exit-related applications without treating it as just a plain bulkhead body.

Dimensions and installation notes

KSR5424 is published at 360 x 110 x 70mm, giving it a compact elongated bulkhead profile that suits doorways, corridors and other linear mounting positions. The installation sheet shows a simple front-screw access arrangement and reminds installers to use suitable fixings and rubber washers to maintain IP integrity.

KSR also notes that, after temporary site installation, the battery should be unplugged before decommissioning the site, and that on re-commissioning the fitting will require a minimum 24-hour charge. That is especially relevant for projects where emergency fittings are moved between jobs.

Why choose this exact SKU

KSR5424 is the right choice when the requirement is a 110V site emergency bulkhead with verified IP65 and IK08 performance, 6500K output, maintained or non-maintained operation and a supplied legend set. It is a focused, purpose-built fitting for temporary site emergency lighting rather than a vague general-purpose bulkhead.
