How to determine correct wiring with between the DS7420i and different DS7400 panel types.
Is the wiring configuration between the DS7420i and DS7400 panel different than with the DS7400Xi?
Will an Answering Machine cause the D168A not to answer when accessed locally?
Some answering machines load down the phone line and cause it to go below 7 VDC. The D168A needs at least 7 VDC to properly process the DTMF tones.
The Bosch Security Systems D221 Answering Machine Disconnect Module allows you to remotely disconnect an answering machine that shares a phone line with a Bosch Security Systems control panel. When the answering machine disconnects the phone line is available to the control/communicator for remote programming (RPS) functions. A Touch-tone® telephone at the RAM site is required to perform the disconnect procedure. The D221 can be installed with an existing modular telephone jack or be a replacement for an RJ-11 jack.
What activates the module to disconnect the answering machine?
From a touch tone phone call the phone line, let the answering machine answer the line. The # key or the 8 key will activate the module.
1) module white jumper cut = # key
2) module black jumper cut = 8 key
**Note: The RAM session is not affected when the D221 restores the phone line to the answering machine. Some answering machines record tones generated during the RAM session. If the D221 Module is used with an integrated telephone/ answering machine device, pressing the activation key ([#] or ) during normal use may activate the D221 and disconnect the device for 3 to 5 minutes.
