detection allows the panel operator to know when the audio on a
particular channel has exceeded a threshold. This is particularly useful
for channels that are inactive periodically, so that the panel operator is
visually cued in the software when audio appears on the line.
Note: Ports 17 through 32 can both send and receive DTMF tones.
When using a TEL-14 interface with the PiCo matrix, it is
recommended that the TEL-14 is connected to one of these
matrix ports for full functionality.
Note: Although ports 1 through 16 are not DTMF-enabled, a
TEL-14 interface connected to one of these ports can
receive incoming calls. However it is not possible to then
use inward DTMF on ports 1 though 16. It is also not
possible to dial out from the matrix on these ports.
Note: A shielded cable should be used.
CONNECTING TO GENERAL-PURPOSE OUT-
PUTS
The male 25-pin D-type socket labeled “GP OUT” allows the Eclipse
PiCo matrix to be connected to eight general purpose outputs (GPOs).
General-purpose outputs are single-pole double-throw relays with
contact ratings of 30 VDC (volts direct current) at 1 ampere.
A general purpose output or “relay” is a switch that is controlled
remotely. The relay is programmed in the Eclipse Configuration
System software to close a contact whenever an intercom panel’s key
is pressed. When the contact is closed, it completes an electronic
circuit’s signal path so that a remote device, such as a light, is
powered.
A GPO can be programmed to mute a speaker, to turn on an applause
light, to turn on a door lock, or to perform a variety of other functions.
For example, to get the attention of a panel operator working in a
high-noise environment such as a control booth a relay can be
programmed to switch on a light at the panel each time the panel
receives an incoming call to ensure that the call will not be missed.
Note: If the GP-OUT port is used the following filter must be fitted
between the PROC-RCC socket and the cable:
CINCH FA-25PS/1-LF 25W D-type in-line 1000pF filter

Note: A shielded cable should be used.
