INSTALLATION
The MUTING RELAY MODULE may be installed adjacent to the speaker(s) it is intended to control or adjacent to a ConTel Station. Cables must be as specified below. Cable entry is application dependant.
IP54 enclosures are available with appropriate glands if required under P/No CC2001/MR/IP54
Module Switching Control Connections

Figures 1 & 2 show the interconnections required when the MUTING RELAY MODULE is connected to a ConTel System. Power is supplied from the ConTel Station. Switching cables will be CW1308 (or similar).

Fig. 1 shows how to connect the MUTING RELAY MODULE when local speakers require switching,

e.g. muting local speakers (to prevent feedback) or activating remote speakers (for paging).

If required two additional ConTel stations may be connected. Connection is made from T5 on each ConTel to T10 and T11 on the MUTING RELAY MODULE.

It is only necessary to connect the closest ConTel stationís T6 to the MUTING RELAY MODULE's T12.

Fig. 2 shows how to connect the MUTING RELAY MODULE to operate when the ConTel station is active,

e.g. to mute local speakers when the ConTel station is switched on for paging or intercom use.

Fig. 3 shows how to operate the MUTING RELAY MODULE in other applications.

To operate the relay all that is necessary is to connect a control switch or similar sink across points A and B.

Two additional control switches may be connected. One to T10 and the other to T11 on the MUTING RELAY MODULE.

Many other applications are possible including speaker selection or dual circuit switching with multi-source systems. Please refer to additional information available from CONNECT COMMUNICATIONS.

Module Loudspeaker Connections

Figure 4 shows the interconnections required when the MUTING RELAY MODULE is connected to a ConTel SYSTEM specifically to mute local speakers to prevent feedback (see Fig 1 for switching control connections) Necessary power is supplied from the ConTel station. Loudspeaker cables will be .5mm 2192Y (or similar).
