Top Tips for Emergency Telephone Installations
Posted on 11 Oct 2019
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
