Option Adapters and Ports

optiPoint 500 acoustic adapter

5.2.2Floating Contacts

In addition, the acoustic adapter also provides two floating contacts. This allows the control of a busy lamp and a secondary bell.

1.First contact (PIN 2 and 3)

This signals the active telephone states:

Handset offhook/trunk key activated

Speaker on/headset active

An external lamp can be used to indicate these states. When the lamp lights up, one of the above-mentioned states is active. However you cannot provide a separate lamp for each of this states.

The lamp receives power from an external source rather than from the telephone itself. However, to prevent this lamp from causing irreversible damage to the optiset telephone or optiset contact adapter, the power supply must range from 24 volts to a maximum of 60 volts, and the lamp itself should not exceed 5 watts. (You can, of course, connect a relay instead of the lamp, taking care not to exceed the connection values mentioned above).

2.Second contact (PIN 4 and 5) This provides the ring input status.

This contact can provide an external signaling mechanism when the telephone rings. This is important when connecting a secondary bell or similar device. Once again, observe the electrical connection values for this connector as well (24 V - 60 V, 5 W; do not connect an inductive load without surge protection). However, you can also connect a relay instead of the lamp, with this relay then controlling the 220 V secondary bell.

>The “door opener“ function is currently only applicable for HiPath 4000 (later also for HiPath 3000 V4.0).The “busy display“ and “door opener“ functions cannot take place simultaneously.

Contact Load

Both contacts can carry the following load:

5 W with 24 V a.c. or 60 V d.c.
