INSTALLATION
Operation
The VM-SRLY provides one Normally Open and
one Normally Closed (Form C) relay connection
for use with Valcom SIP Doorphone/Intercom
devices. The relay is activated by pressing a digit
on the calling telephone. The relay is typically
used to activate door entry equipment, gates, etc.
Mounting
The VM-SRLY can be mounted to a solid surface
using the double-sided tape affixed to the back of
the module, or can be attached using the #4 x ¾”
screw included with the module. See Figure 1.
Figure 1. Mounting
Power / Signal Connections
The power and signal connections are provided
to the VM-SRLY by a four wire connector. The
recommended wiring uses two pairs from a
standard Category 3 (or better) twisted-pair
cable. The screw terminal block is removable for
ease of installation. Make the connection from
the Valcom SIP Doorphone/Intercom device to
the VM-SRLY following the diagram shown in
Figure 2.
Relay Connections
Access to the form C relay is provided via a three
pin screw terminal block on the VM-SRLY. The
screw terminal block is removable for making
connections. The Common contact is the middle
terminal. The normally open contact is labeled
“NO” and the normally closed contact is labeled
“NC”. Make connections between NO and
Common, or NC and Common, as necessary.
See Figure 2.
SETUP
No setup is necessary for the VM-SRLY.
Information related to activating the VM-SRLY
from a Valcom SIP Doorphone/Intercom device
will need to be programmed into the SIP
Doorphone using a computer. The PC used for
programming should be connected to the same
subnet as the Doorphone. Setup will be done
using the IP Solution Setup Tool. Download the
