An introduction to the product and its key features
Elmdene ELM-RES-KIT — Fire & Security Resistor Kitis a purpose-built resistor assortment designed to meet the everyday needs of fire and intruder alarm installers, service engineers and maintenance teams. Packaged as a compact, labelled plastic compartment box, the kit contains 270 commonly used resistor values suited to end-of-line (EOL) monitoring, tamper loops and device configuration in both conventional and addressable alarm systems. The kit’s portability, clear labelling and breadth of commonly required resistor values make it a practical on-site resource that reduces trips back to the van and speeds fault finding and commissioning tasks.
Key features at a glance:
- 270-piece assortment covering nine commonly used values (30 pcs of each value).
- Labelled plastic compartment box for rapid part identification and organised storage.
- Tailored for EOL monitoring, zone supervision, tamper circuits and device configuration.
- Compact and lightweight (approx. 320 g) — easy to carry in tool bags or service vehicles.
- Reported RoHS and CE compliance per distributors; buyers should refer to Elmdene datasheet for confirmation.
Detailed description of specifications and benefits
The Elmdene ELM-RES-KIT is intentionally straightforward: it provides a curated selection of resistor values that are repeatedly required in fire and security systems. Below is a breakdown of the documented specifications and what they mean in practice for installers.
- Total quantity: 270 pieces, divided into nine values with 30 pieces each.
- Values included: 470 Ω, 680 Ω, 1 kΩ, 2.2 kΩ, 3.9 kΩ, 4.7 kΩ, 6.8 kΩ, 10 kΩ, 20 kΩ.
- Box dimensions: 275 × 190 × 42 mm — shallow footprint that fits most vehicle trays and workbenches.
- Approximate weight: ~320 g — negligible burden for mobile engineers.
Distributors list the product as RoHS and CE compliant, reflecting expected regulatory conformity for components in the EU/UK marketplace. That said, listings vary and resistor power ratings and tolerances are not consistently stated across reseller pages. Elmdene’s manufacturer datasheet should be consulted to confirm resistor wattage and tolerance before using the parts in applications where those parameters are critical.
- Time savings: having dozens of each commonly used value on hand eliminates repeated trips to suppliers or rummaging through mixed parts bins.
- Organised workflow: labelled compartments reduce errors when selecting resistors for EOLs, jumpers or detector settings.
- Versatility: the chosen values cover the majority of EOL and monitoring requirements across many conventional and addressable systems.
- Cost-effective: competitively priced for a trade kit — attractive for both individual engineers and fleet provisioning.
Use cases and scenarios where the product excels
The ELM-RES-KIT is particularly well-matched to the practical routines of fire and security professionals. Here are common real-world scenarios where this kit proves valuable.
During the initial wiring and configuration of alarm panels and detectors, technicians often need specific resistor values to set device options or complete EOL monitoring circuits. With 30 of each commonly used value, the kit supplies enough parts for multiple installations without restocking between jobs.
When diagnosing faults or replacing components on service calls, having the usual resistor values at hand allows engineers to isolate issues quickly and fit replacements on the spot. The labelled box speeds identification and reduces downtime at the site.
Temporary or diagnostic resistors are frequently needed to simulate loads, check wiring continuity or temporarily configure a panel while evaluating faults. The variety in the kit makes it simple to try different values safely and methodically.
For trainees learning alarm wiring and supervision concepts, the kit is an excellent learning aid: they can practice fitting EOL resistors, configuring tamper circuits and testing different resistor-based settings without consuming bulk stock.
Comparisons with similar products in the market
Resistor assortments are common, but the ELM-RES-KIT targets a specific niche — alarm installation consumables — and that focus differentiates it from generic resistor kits. Here’s how it stacks up in a few key areas:
Generic electronics resistor assortments often contain hundreds of values with small quantities of each, geared to passive electronics prototyping. By contrast, the Elmdene kit concentrates on the handful of resistor values most used in fire and intruder alarm work and supplies large quantities (30 each). For alarm engineers this is a practical advantage: fewer spares of irrelevant values, more of what’s actually needed.
Many competing kits use unlabelled trays or mixed blister packs. Elmdene’s clearly labelled compartment box improves on-the-job speed and reduces selection errors. For teams managing multiple vehicles or communal toolboxes, consistent labelling and separation of values is a small but meaningful productivity gain.
Observed public reseller prices vary (approximately £13.80–£24.60), while the suggested RRP sits at around £25.15 and typical supplier cost is listed as £21.12. Compared to generic resistor assortments of similar piece counts, the Elmdene kit offers greater value for the alarm trade because the mix is tailored to the trade’s needs. For buyers, the deciding factors will be content relevance, build quality and documented compliance rather than simply parts-per-pound.
Elmdene (Potter Electric Signal) is a recognised brand in the fire and security space. That brand association and the kit’s distributor-reported RoHS/CE status are advantages versus unbranded assortments where provenance and conformity are unclear. Buyers who require formal certification should request the Elmdene datasheet to verify ratings.
Customer testimonials and user feedback
Public, detailed customer reviews specific to the ELM-RES-KIT are limited. However, reseller notes and installer feedback commonly highlight a few recurring positive points:
- “Practical selection of values” — installers appreciate the choice of resistors tailored to EOL and tamper configurations.
- “Good labelling saves time” — the compartment box and labels are repeatedly cited as time-savers on-site.
- “Compact and easy to carry” — users report the kit fits well in service bags and vehicle trays.
Constructive comments from the trade typically focus on the lack of standardized published resistor wattage and tolerance data in reseller listings. Where this matters — for example, in circuits with higher power dissipation — engineers are advised to consult the Elmdene datasheet or contact the supplier for clarification.
Conclusion: why the Elmdene ELM-RES-KIT is a great choice
The Elmdene ELM-RES-KIT is a practical, trade-focused resistor assortment that addresses the everyday needs of fire and intruder alarm professionals. Its concentrated selection of nine values in meaningful quantities, combined with a labelled compartment box and compact footprint, delivers clear on-site advantages: faster commissioning, more efficient fault finding and a reduced need for repeat parts runs. While buyers should confirm resistor power and tolerance specifics via the manufacturer datasheet where those parameters are critical, the kit represents a cost-effective and organised solution for engineers, service teams and installers who work regularly with EOL monitoring and device configuration.
For teams looking to kit vehicles or supply technicians with a compact, job-focused resistor set, the Elmdene ELM-RES-KIT is worth considering. It balances the convenience of a ready-made assortment with the credibility of an established brand, making it a solid addition to any fire and security engineer’s toolkit.
