Relays are essential components in access control and video surveillance systems. They are used to switch circuits on and off, control alarms, or reverse polarity in security setups. Common types include SPDT relays, which allow switching between two circuits, and multi-pole relays for more complex control tasks. Some relays are enclosed for durability, while others are designed for quick installation in control panels.
Products like the Linear 2500-250 relay and the Interlogix 405-03 polarity reversal relay are typical examples. Reversing relay modules from Bosch and relay outputs from United Security Products help automate security functions. These relays are suitable for various security and automation applications, providing reliable switching and control options for system integrators and installers.
