Gain an even higher level of protection for facility-wide fire and life safety systems with System Sensor multi-voltage conventional relays. These relays control high-current switching applications in an overall fire protection system, such as fan and damper assemblies, doors, elevators, air handling systems and other types of system interfacing.
These relays also act as accessories that interface with other System Sensor protection systems, such as duct and conventional smoke detectors, and bring an additional level of security and safety to these systems. Relays can be configured on either a fixed basis or can be programmed to activate under specific input conditions.
Examples of relay functions include:
• Relays can hook to HVAC system detection to prevent dissemination of smoke through fans, dampers and air-handling systems.
• For doors, the relays can be programmed to close doors to certain building zones to keep smoke from spreading or to unlock doors to improve egress.
• Elevators can be controlled by relays to ensure appropriate elevator recall operation.
Relays can also interface with voice evacuation, security and mass notification systems to ensure, for instance, that building management and occupants have accurate, up-to-the-minute information regarding emergency situations that impact other components connected to the fire system. Monitoring of kitchen systems and suppression systems may also be enhanced with relays.
System Sensor offers three types of relays, each of which feature activation LEDs and is available in multiple voltages to accommodate different applications. The three available series of relays are: the epoxy-encapsulated potted with pigtail series relays; steel enclosure series relays, which are mounted into a steel enclosure with a removable front cover for easy access; and track-mount series relays, which have terminal strip field wiring connections.
System Sensor technical support can advise which relay series is best suited for any particular facility or application.
