Gent replacement parts: what to send with an enquiry

The part number, panel details and photographs that help us check a replacement enquiry.

Midland Fire Direct

Start with the complete part number, a photograph of the panel and a short note explaining what needs replacing. If you have the service record, include the main controller and loop-card versions.

That gives us something useful to work from even if the label is worn or you are unsure which part to request.

The details that help

The full part number, including every letter after the numbers
Which variant is fitted. Sounder, speech and visual-alarm functions matter when choosing its replacement.
A clear photograph of the panel front and its model label
Whether the system is Vigilon, Compact, Nano or an SMS SenTRI model. A photograph also helps distinguish panel generations.
The main controller and relevant loop-card versions, if recorded
Whether the proposed device meets the system's firmware requirements. The two versions need checking together.
What the existing part does
Detection only, audible warning, speech, visual warning, or an interface operating other equipment. For an interface, include what it controls and any existing specification.
What prompted the enquiry
A failed part, an addition, a fault message, or a planned panel change. Copy any displayed message exactly and include the device address if known.

Use existing service records or ask the maintaining engineer for anything that needs the panel opened or a device removed. If a detail is missing, send what you have and say which information is unavailable.

Why the panel matters as much as the part

Gent's device requirements vary by main-controller and loop-card version. A newer part number does not establish compatibility on its own.

For example, high-power visual alarm devices can behave differently on older loop cards. A replacement enquiry needs to account for the visual warning the device must provide, as well as whether it is recognised by the panel.

A Vigilon control-card enquiry needs the panel generation too: the manufacturer's upgrade chart pairs firmware chips with particular displays and doors. An engineer's existing photographs of the inner door and board labels are useful here.

Two different parts that can both be described as a “control board”. Include the full code and panel details in your enquiry; appearance alone does not establish compatibility.

Include connected equipment in a panel-change enquiry

Mention any repeat panels, mimics, networked panels and interfaces. Their compatibility needs its own check; a replacement at the main panel can affect equipment elsewhere on the system.

For an SMS SenTRI system, give the model exactly as it appears on the panel. SenTRI 1, 2 and 4 should not be treated as one replacement case.

Send your enquiry

Use Request a quote to send the part number and available system details. Include the quantity required and say whether you need a device replacement, a control-card replacement or help identifying the equipment.
