ページを印刷する4 External Signalling OPTIONAL relay not fitted as standard
The A103 provides a galvanically isolated, normally open volt-free contact for an external signalling
device, which closes when a ring signal is received by the A103 telephone.
Connection to this contact is made via the terminal block located inside the termination chamber
labelled as B1 and B2.
The contacts are rated as follows:
5 Internal BP004 battery connection.
This battery will be disconnected upon despatch from the factory to prevent full discharge. It will
therefore need to be reconnected during the installation process before securing the termination
chamber cover.
To reconnect the battery, simply connect the 4 pin socket and plug inside the termination chamber together.
Note: The battery should be fully charged before use. If the battery needs to be recharged, see section
"Battery SAFE AREA tests" within this guide.
6 Programming and configuration changes
The telephone polyester enclosure must NOT be opened in the hazardous area!
Note: The polyester phone case must be opened to access the store button used during programming and
the jumper links for configuration changes.
To maintain the Ingress Protection level of IP 55, all attempts should be made to maintain cleanliness during
this process. Also ensure seals are located correct and free from damage.
