SigCom MNS-3-REL 3 Relay Expansion Kit, 3 Relay

Add reliable, professional-grade signaling to your security or monitoring installation with the Signal Communication MNS-3-REL 3 Relay Expansion Kit. This relay expansion card provides three Form-C relay contact outputs so you can drive external notification devices, trigger auxiliary systems or create dedicated Active and Trouble indicators without replacing your primary controller. Two relays are commonly assigned to Active and Trouble status while the third serves flexible uses such as tamper alerts, door control or third-party integrations.

Built for security, surveillance and alarm monitoring environments, the MNS-3-REL is easy to wire into existing panels and access control systems and delivers isolated, fail-safe switching for low-voltage control circuits. The compact form factor reduces installation footprint and speeds deployment during system upgrades. Whether you need additional outputs for remote annunciation, logging or automation, this Signal Communication relay kit streamlines integration and enhances situational awareness across your security infrastructure.

Upgrade your system today—add the MNS-3-REL to extend monitoring and control capabilities in alarm, surveillance and access control applications.
