Valcom, Inc VM-SRLY Smart Relay for VIP-176

Smart Relay for VIP-176

The Valcom VM-SRLY is a dedicated smart relay designed for use with Valcom SIP Intercoms. It provides a single Form C relay output with both Normally Open and Normally Closed contacts to control auxiliary equipment such as electric door strikes or gate openers. Smart signalling reduces the possibility of tampering for secure access control. Installers integrating SIP intercom systems will find this unit essential for triggering external hardware.

Compatibility Check

Verify that your existing installation uses Valcom SIP Intercoms, specifically the VIP-176 model, as this relay is designed for that platform. Confirm that the auxiliary equipment you intend to control operates within the electrical ratings of a single Form C contact. Ensure your wiring plan accommodates both Normally Open and Normally Closed connection options for the desired fail-safe or fail-secure behaviour. Buyers using non-Valcom intercoms or requiring multiple independent relay outputs should look elsewhere.

Build and Connections

The unit provides a single Form C relay output, offering both Normally Open and Normally Closed terminals for flexible wiring with auxiliary devices. This contact arrangement allows daily operation of door strikes or gate openers in either fail-safe or fail-secure configurations. Smart signalling built into the relay helps resist tampering attempts on the control line. The compact form factor suits installation inside standard electrical enclosures or intercom housings.
