By the 1930s, Gent were manufacturing bells, clocks, power supplies, fire alarm systems, telephones and signalling and recording equipment.

The company also produced sirens as wells as electrical parts for aircraft communications and radar equipment.

Due to the success of the Warblers, other companies started manufacturing similar electronic sounders such as Protec's SR2.

Chloride Gent's other popular products included the Model 1102 Manual Call Point, which could be fitted with an optional hammer attached to a chain.

Gent continued making sirens such as the Model 1500, often used in large open areas or industrial spaces.

The company also introduced the 1195 Manual Call Point, distinguishable by its square design as opposed to the rectangular design of the Model 1102.The current Gent addressable protocol, called the Gent 3217 protocol, started with the launch of the System 3400 fire alarm system in 1985.

It was not until 1987 that loop-powered sounders would be available for system 3400, partly due to the difficulties in reducing their power consumption so as to not to affect loop communication.

The Gent 3217 protocol supports multiple spurs and a mesh-like configuration although this was not utilised in the final product GB expired GB2168517B, David Appleby & Duncan Miles Johnson, "Information transmission system", published 1988-07-20, issued 1988-07-20, assigned to Novar Systems Ltd .

In 2019 Gent announced that they were officially discontinuing the 34000 device range,[5] citing problems with part availability.

The S-Quad adapter base is not compatible with the 19279-01 Semi flush mounting kit or the 19279-10 Sensor Trim Ring.

In 1999 the Vigilon was re-released, due to the release of a new set of sounders, detectors, and manual call points.

[3] In 2005, the Vigilon panel design was updated, and more LEDs to display more faults and issues to the end user.

Some earlier BS Vigilon panels can be upgraded with the V3+ main controller card, allowing them to run S-Quad devices.

In 2007, Gent released the S4-34800 call point range, officially completing the initial S-Quad line.

A minor revision to the panel, it added little functionality, bearing more cosmetic changes than functional changes, however a new SD card reader was added to allow configuration information to be transferred to the Vigilon using the SD card slot.

In 2019, Gent released the SAFE, a device and interface system designed to reduce false alarms in residential buildings.

[10] Gent also revised the S-Quad and S-Cubed, with software V1.20, however there aren't any noticeable difference besides an increased tone hold length and improved quality of voice messages on voice sounders, as the devices are functionally and visually the same as the previous versions released in 2014.

The detector temporarily disables itself to ensure that the testing process does not cause a system activation and/or a fire evacuation.

In addition to this, the app allows for the Fire LED on each sensor to be tested, which is currently a pending requirement of BS5839-1, and for the detector's self-disablement feature to be temporarily disabled so that the self-test feature to activates the sensor, allowing for the cause and effect logic of the Vigilon System to be tested.

This means that these sensors also feature better, more accurate smoke detection and higher quality voice messages, while remaining compatible with the S4-700 and S4BK-700 detector bases.

[11] It appears that the previous Mark 2 and Mark 1 S4 detector range will remain compatible and will be able to be installed on the same loop as the new self-test detectors, meaning that an existing, compatible system can have its sensors upgraded to self-test models gradually, without affecting the functionality of the system.

The Vigilon Compact does not feature a full QWERTY keyboard and requires a different form factor of loop card.

The Nano has a drastically different user interface to both Vigilon panels and requires its own separate commissioning software.

For many years, Gent has released commissioning software for its analogue addressable range of fire alarm control panels.

Signal 3 in the 2019 update was changed slightly from "Attention please, This is an emergency, please leave the building by the nearest available exit!"

EN54 compliant glass with a white background was also made available to replace the non-compliant transparent design on both conventional and addressable systems.

During the early 21st Century and continued development of Vigilon, Gent released a new range of hybrid wireless products – Plexus.

Plexus used mesh networking technology with a loop-powered transceiver allowing addressable loops to be extended with wireless sensors, sounders and manual call points.

The company sold Gent products under the SMS brand name using different marketing strategies.

Its main design and manufacturing centre and headquarters were at the Faraday Works in Temple Road, Leicester; but after World War II, the company expanded into nearby Kibworth.
