Kentec Launches New 4-Way Relay Unit To Ease Maintenance Without Comprising Safety 18 Sep 2018
Kentec, a leading life safety control systems manufacturer, has launched a 4-Way Relay Unit aimed at both conventional and addressable fire alarm/extinguishing systems enabling key maintenance to be undertaken without compromising safety.
The 4-Way Relay Unit enables simple isolation of third party systems (e.g HVAC, security, access control etc) connected to the fire alarm system, this allows repairs and maintenance to be carried on the fire alarm system without compromising the functionality of the third-party equipment. Volt-free contacts provide safe switching of high and low voltage lines.
Four double pole relays are provided, three relays rated 240VAC 7A, 110VAC 10A, 24VDC 10A for high current switching and one relay rated 125VAC 0.5A, 30VDC 2A for low current switching all housed in a robust sheet steel enclosure. Relays can be activated by using switch negative signals from up to four control panels. Isolation of the relays is enabled through simple slide switches, one per relay, with simple LED’s displaying the isolation status of each relay.
Kevin Swann, Managing Director at Kentec, says the 4-Way Relay Unit is an important addition to Kentec’s portfolio of high-quality and reliable safety control systems:
“The 4-Way Relay Unit enables easy isolation for installers and engineers, and with relays each up to 10Amps it has the capacity to isolate high power equipment. It is the ideal demarcation point for third party equipment.”
