JIEXI builds deck alerts, instrumentation and machinery components on one factory floor, and this page is built to help you buy from that range without a costly first mistake. Work through the vetting questions that separate a genuine marine spare parts manufacturer from a trading desk, then apply the same tests to any marine safety equipment manufacturer whose alarm units have to survive salt, spray and constant vibration. From there, scan the range index, match your scenario to a specification, and send the six RFQ inputs that let an engineer price your line item correctly the first time.
Every point below is a request you can send to any candidate supplier, whatever they make. The SHD / SHDP warning horn is used only as a worked example where it makes the question concrete.
A scope that covers marine electrical assembly tells you batch-to-batch variation is controlled — the thing that matters when the same model ships across a whole fleet.
Grade claims are the easiest thing to copy and the hardest thing to verify after delivery.
On open deck, the enclosure rating decides the service life of the entire unit, not just its enclosure.
An alarm ordered against the wrong supply turns into a spare-parts problem before it ever reaches the deck.
Matching the original fit removes adapter work and re-drilling during a short port call.
Variant selection, not factory capacity, is the usual reason a lead time moves.
A lampshade and a rotating mechanism travel badly in loose packing, and nobody sees the damage until the vessel is in service.
Consumable-level spares keep the unit in service without a repeat full-unit purchase and a second freight bill.
Read the mounting location and the noise environment first, then confirm the specification line that follows from it. Every confirmation below is a question for the supplier, not an assumption.
| Operational scenario | Specify this | Confirm before ordering |
|---|---|---|
| Open deck crane, daily salt spray and washdown | IP66 sealing structure, SUS316L stainless steel protection grid, anodized aluminium alloy base | Which guard is required — standard SHD or SHDP with the protective net — and the mounting detail on the mast or bracket. |
| High ambient noise — engine room or steel plant machinery | Rotating bulb reflector warning light and signal tone horn combined in one body | The usable sound figure and the distance at which it was measured, since the product page presents more than one value. |
| Mixed fleet supply voltages | DC12, DC24, AC110 or AC220 variant of the same model | The bulb stated for each voltage row and whether a transformer is needed on AC lines. |
| Multi-station alarm zoning on one deck | Red, yellow, green or blue lampshade colours | Colour assignment per station and whether mixed colours can ship in one consignment. |
| Weight-limited mast or bracket mounting | Lightweight body stated at 3.18–4 kg | The exact weight and mounting interface for the configured model, not the family figure. |
| Outdoor equipment and steel industry sites | High-impact PC lampshade, sealed enclosure, outdoor-suitable construction | The ingress-protection documentation for the site, and impact expectations where the unit is exposed to falling debris. |
Six inputs turn a general enquiry into a priced, dated offer. Send them in one message rather than a series of replies, and the quote comes back usable.
| Input | Why it matters | If missing |
|---|---|---|
| Part number or model SHD or SHDP |
Fixes the base configuration, the guard type and the body construction. | You are quoted a family, and the delivered unit may not carry the protective net you assumed. |
| Nameplate photo | Confirms the existing unit's voltage marking, bulb designation and mounting. | Cross-referencing becomes guesswork and the quote is delayed by a round of questions. |
| Drawing or mounting detail | Confirms bracket interface, cable entry and clearance around the lampshade. | Adapter work and re-drilling risk after delivery, often during a short port call. |
| Supply voltage DC12, DC24, AC110 or AC220 |
Drives the bulb selection, the current draw and any transformer requirement. | The unit arrives unmatched to the vessel supply and cannot be commissioned as planned. |
| Quantity by model, colour and voltage | Sets the MOQ tier, the production run and the packing configuration. | Price and lead time stay provisional and cannot be committed in writing. |
| Vessel IMO and delivery port | Sets the shipping documentation and the freight routing for the delivery window. | Freight cost and delivery timing cannot be confirmed, so the landed cost stays unknown. |
These are the patterns that signal an unverified document. Each one comes with the question that resolves it, so you can keep a supplier on the shortlist or drop them on evidence rather than instinct.
When marketing text and a specification table disagree, the lower, qualified figure is the one to plan with until a measurement report arrives.
Real case: the SHD / SHDP description states up to 118 dB, while the volume column in the same page's table reads 108–113 dB.“IP66” alone is a catalogue entry. Ask for the test standard, the test date and the report reference, or treat the rating as unverified for on-deck service.
Resolution: request the ingress-protection document alongside the quotation, not after the order.If a supplier cannot state the stainless grade in writing, the difference between SUS316L and a generic stainless part stays invisible until corrosion appears in service.
Resolution: ask for grade declaration on the protection grid and any wetted or load-bearing part.A decibel figure without a stated distance and ambient condition is not comparable between suppliers, and cannot be used to size an alarm for a noisy zone.
Resolution: ask “at what distance, in what background noise, and with which voltage applied?”In the SHD / SHDP table the AC110 and AC220 rows list a 12V15W bulb while the DC rows list 12V15W G23 15S and 24V15W. Cross-row entries like this need an explicit answer.
Resolution: ask which bulb ships with each voltage row, and whether a transformer is supplied.Identical layout, identical wording and identical typos across several unrelated “manufacturers” mean the document was never written for the product in front of you.
Resolution: request a model-specific dimensional drawing and a nameplate photo of a unit already produced.One real line item, specified from the product page: a self-supporting sound and light alarm for heavy-load service, with the warning light and signal speaker built into a single body. Suitable for all kinds of cranes, ship machinery, steel industry sites and outdoor equipment sets.
| Model | Volt | Current | Bulb | Volume | Weight | Colour |
|---|---|---|---|---|---|---|
| SHD / SHDP | DC12 | 3A | 12V15W G23 15S | 108–113 dB | 3.18–4 kg | Red, yellow, green, blue |
| SHD / SHDP | DC24 | 2A | 24V15W | |||
| SHD / SHDP | AC110 | 450mA | 12V15W | |||
| SHD / SHDP | AC220 | 230mA | 12V15W |
Choose SHDP where the lampshade needs a protective net — deck cranes, steel plant machinery and exposed outdoor equipment. Choose SHD where the lens is already shielded by position.
Order the colour to match your alarm convention, not the other way around. Red, yellow, green and blue are the listed options.
Match the vessel or site supply from DC12, DC24, AC110 or AC220, and confirm the bulb and current for that row before the order is released.
Send the RFQ inputs from the table above in a single message. Part numbers, nameplate photos and drawings are all welcome, including for items that are not listed in the range index.

View productmoq is set per model, for the warning horn line, per colour and voltage variant, so there is no single number that covers the whole range. ask for the moq table for the exact model you need before finalising order quantities, and agree trial or sample terms in writing.
the main drivers are the model (shd or shdp with the protective net), the voltage variant, the lampshade colour and the order quantity. confirm lead time for the exact configuration rather than for the product family, and treat shipping time as a separate item.
the unit is stated at 3.18–4 kg, so export shipping is normally carton-based with protection around the lampshade and the rotating mechanism. ask for the carton specification, moisture protection, pallet marking and total shipping weight at quotation stage.
ask for a spare-parts list to be issued with the quotation. the lampshade, the bulb and the sus316l protection grid are the parts most exposed in service, and having them on the first order avoids a second shipment later.
incoterms and payment terms are confirmed in the written quotation for your destination and order size. state your preferred term and delivery port with the rfq so freight can be priced inside the same document.
validity depends on material and freight conditions at the time of quoting, so ask the supplier to state a validity period on the quotation itself. if an order is placed after that date, request a re-confirmation of price and lead time.
