RTU-292 Operations Manual

2.8.12 PASSWORD PROTECTION

Dipswitch SW1-5 enables or disables the RTU-292's password protection feature. Password protection prevents unauthorized access to the system from the PSTN line when the RTU-292 is in the Automated Operation Mode. (See section 3.7 for a full explanation of Automated Mode Operation and the use of the Password Protection Feature). The factory setting is disabled, SW1-5 Off. To enable the password protection feature, turn SW1-5 On. The factory default password is “1 2 3 4”, but may be changed to any number up to 10 digits long. See Table 3-2.

2.8.13 VOICE PROMPTS

Dipswitch SW1-6 enables or disables the use of Voice Prompts in the RTU-292. This feature should be enabled only if the Voice Prompt Option is installed. See section 3.7 for an explanation of the Voice Prompt feature operation, and section 7.2 for field installation. The factory default setting: disabled if the Voice Prompt Option is not installed and enabled if it is.

2.8.14 LOCAL PHONE / LOCAL PHONE RING-THROUGH

Dipswitch SW1-7 enables or disables the RTU-292 Local Phone Option. This feature should be enabled only if the Local Phone Option is installed. The factory setting is: Disabled (SW1-7 Off) if the Local Phone Option is not installed and enabled (SW1-7 On) if it is. See section 3.7 for an explanation of Local Phone Option operation, and section 7.3 for field installation instructions.

SW1-8 enables the Local Phone Ring-Through feature. This causes the local phone to ring whenever a call is received by the RTU-292 via the PSTN input. When disabled, the local phone may still be used to send and receive calls, but will not ring when a call is received. Set SW1-8 to On to enable Local Phone Ring-Through, and Off to disable this feature. This switch should always be set to Off (disabled) when the Local Phone Option is not installed. The factory setting is On (enabled) when the Local Phone Option is installed and Off (disabled) otherwise.
