Most emergency telephones will be installed without issue but if you do run into trouble here are some helpful tips that our technical team have compiled to assist you in resolving any problems.
Wiring:
- Check the wiring connections. It is possible for a wire to become detached during installation
- Check the alarm button configuration/wiring, as there are two connection types (Normally Open or Normally Closed) – some also have a voltage across them due to the siren being connected
- Check if the Pictograms switch on a Positive or Negative voltage. (Some systems will use or switch the pictograms on a Positive or Negative Common)
Programming:
- Keep programming simple
- Confirm telephone numbers are programmed correctly, as each manufacturer has their own protocols
- Only change settings if required; unnecessary changes can affect how the equipment operates
- Consider using the Janus programming service
Telephone line:
- Check your telephone line is active before you make an alarm call
- The best way to check if a telephone line is active is to check by calling a handset
- Plug a telephone handset into the available telephone socket and call your mobile; this checks the telephone line from the main socket is working and shows you the line number on your mobile
- For a digital line you need an Analogue Telephone Adapter (ATA), as telephones require an analogue telephone line.
Interference:
- Always consider your wiring routing and any consequences it may cause
- Poor telephone line routing can cause electrical interference issues such as poor two-way voice communication
- Depending on the types of devices being used, try to keep different pieces of equipment as far away from each other as possible to minimize risk of interference
