Fike Develops Supervisory Switches

11 February 2016

SUPERVISORY TECHNOLOGY COMPLIES WITH AUSTRALIAN STANDARDS    For the first time a Fire Suppression System complies completely with the Australian Standard AS ISO 14520 with the release of the new supervisory switches which monitor the position on the actuator on the agent storage container. 

Clause of As ISO 14520 states “Any condition that inhibits the discharge of the extinguishing agent shall cause the ‘EXTINGUISHING SYSTEM INOPERATIVE’ visual warning device to illuminate”. Up until now, no extinguishing system is able to confirm that that the system actuator is actually installed on the agent storage container. Obviously if the actuator is not installed on the cylinder, (perhaps removed for maintenance) the system is inoperable.
 To meet this requirement Fike has designed two devices, one that will supervise the connection of the Impulse Valve Operator (IVO) on FM-200 systems and the other will supervise the connection of the Universal Valve Operator (UVO) on ProInert systems. When connected to fire alarm panel, and installed in place of the standard U-clip, the supervisor comes in contact with an installed Valve Operator. If the supervisor is removed or the Valve Operator is not in place, the panel will provide an audible and visual notification.
This supervisor replaces the simple U-clip by creating an assembly that molds the supervisor and U-clip into one sealed unit. The rest of the assembly consists of six wires housed in stainless steel flex conduit, and an electrical connector for a 15mm knockout.
When these supervisory switches are coupled with the IVO or UVO or which are UL Listed, FM Approved and ULC Listed, the system can be configured and a fault can be detected on the Control and Indicating Equipment (CIE) when the IVO is removed, fully complying with the Australian Standard AS ISO 14520 for Gaseous Fire Suppression Systems.
