Edwards is a multinational corporation owned by United Technologies Corporation that specializes in fire protection, signaling, and communication systems. Edwards was founded in by Robert S. Edwards and David Rousseau. The two designed and manufactured an electric igniter for gas-powered light fixtures.
After Rousseau departed the company, Edwards began making doorbells and simple burglar alarms, obtaining a patent for the first electric bell in Throughout the rest of the decade, the company's product line expanded to include electric annunciators, door openers, clocks, and switches.
In , Edwards provided the first electric closing bell for the New York Stock Exchange, a well-known sound which continues to be made by an Edwards signal to this day.
The company continued to perfect its electric signals throughout the early 20th century, introducing a series of heavy-duty watertight bells and buzzers in the s for use in maritime, military, and mining applications.
In the s and s, Edwards further expanded its product line with fire alarm systems, sprinklers, and watchman's tour systems. By the midth century, fire protection would come to be the company's most notable and profitable industry, establishing itself as one of the major brands in the fire protection field.
In , a new plant was opened in Owen Sound, Ontario to accommodate increasing demand for fire alarm and electric clock systems. In , the company introduced its recognizable series of "teardrop" coded and non-coded fire alarm pull stations, acclaimed by the Associated Press for their simple foolproof design. The non-coded series pull stations are still manufactured today with little difference from the original design.
In , the company was purchased by General Signal Corporation and adopted the brand name "Edwards GS" for certain products. Throughout the s and s, the company modernized its line of fire alarm products with modular control panels, ionization and photoelectric smoke detectors, and compact audible and visible signaling appliances. Among Edwards's notable fire alarm panels were the , a custom modular conventional panel introduced in the s and known for its enduring reliability, and the , a microprocessor-based multiplex panel with voice evacuation and video terminal capability introduced in the s.
Meanwhile, the "Edwards" name was used for general signaling and accessory products. In , EST introduced the Signature series of intelligent pull stations, multisensor detectors, addressable modules, and loop controllers, along with the Integrity series of notification appliances.
Signature series smoke detectors were among the first multi-element devices, comprising photoelectric, ionization, and heat sensor elements in one housing for more accurate detection. Taking full advantage of Signature series intelligent devices, the EST2 featured device mapping, integrated audio, and networking for up to 5 nodes. The aging IRC-3 was replaced with the EST3 in , bringing the new features of the EST2 to a large panel capable of multiplexed audio and campus-size token ring networking up to 60 miles.
In , EST introduced the Genesis series of low profile notification appliances, featuring the smallest device footprint of any notification appliances at the time. Genesis series devices also incorporate strobes without reflectors and field-selectable candela and wattage settings. The transaction was a product of SPX's "fix, grow, sell" strategy in which they would acquire a company, grow it to substantial profitability, and sell it to a larger conglomerate to redeem the company's value for SPX's shareholders.
In addition to marketing EST's product line, GE used EST technology to create two new brands: Vigilant, a series of non-proprietary high-end addressable panels compatible with Signature series devices and introduced in , and FireworX, a non-proprietary series of small FireShield-style conventional and addressable systems compatible with ESL devices and introduced in Despite their similarities to EST products, these products were distributed through separate channels and did not require dealers to be EST strategic partners.
The recession, loss of longtime leaders within acquired companies, and general lack of experience in the industry have been cited as reasons for the transaction. The company also updated the Signature series of smoke detectors with a new design and modular carbon monoxide detection capability. Today, EST markets a full product line of conventional and addressable fire alarm and emergency notification systems, including: EST3: A large addressable, modular, and network-capable control panel intended for large to campus-size applications.
EST3X: A 1, point addressable, modular, and network-capable control panel intended for medium to large-size applications. QuickStart QS1: A point modular single-loop control panel intended for small to medium-size applications.
