# Receiving and Acknowledging Alarm Calls

When the Catalyst makes a Notification call, it begins by dialing the first eligible destination. When the dialing string is completed, the unit will begin to recite the Unit ID message and a prompt to press a 5 to begin session (or a PIN if PINS have been configured). When you answer, you will begin hearing the message at some arbitrary point in the sequence. Simply wait for the product to recite the Unit ID Message and follow on from there.

If PINs (Personal Identification Numbers) have been established for the RTU, there will be a request for entry of your user PIN (Personal Identification Number). Enter your PIN at this time. Regarding entry of PINs, your PIN entry is considered complete upon your issuing either a *, # # #, or by waiting three seconds with no further entries.

Next will follow a preliminary voice report of certain significant global (not pertaining to any one channel) situations. The following is a list of special warning messages that are delivered during an Over the Phone (OTP) session if necessary. They are announced after the Unit ID message, and before the channel status report:

- Unreported Power Failures
- Low Battery detected
- Time of Day (TOD) Clock Reset
- Phone Line Failures
- Unit is Disarmed
- No Destinations are Programmed
- Log File Overflow detected
- PLC Network Scan is Disabled
- Network with All Channels in Communication Alarm

If no such conditions apply, then this preliminary report will be skipped.

Next will follow an Alarm Report, reporting the status of any channel(s) that are linked to this Destination (the phone number where you are receiving this alarm call) and which have an unacknowledged alarm. Certain phrases may also be automatically appended to the recorded message report of a given channel, as listed later in this topic. These phrases, called Tag Words, provide additional information about the specific state of the channel.

If there is a communications failure on the network, this fact will be reported, followed by a report on all channels linked to this destination group. In this case, the phrase "SNA Alarm" will be added to the channel's report. Note that the channel reading will reflect the last value read before failure of communications.

Next you will hear a warble tone and menu options requesting entry of either a touch-tone "9" or "3" to acknowledge, or a 1 to enter programming mode in preparation for changing the RTU configuration during this call.

If PINs have been configured, the prompt also mentions entering a 5 to repeat the menu.

Entering a "9" will cause the acknowledgement of the unacknowledged alarms you have just heard about, followed by a report of any other channels included in your Destination group which had already been in an acknowledged alarm state prior to this alarm call.

Entering a "3" will do the same, except you will then hear reports of all alarms including any that are not in your Destination group.

In the special case where some new unacknowledged alarm had tripped during this call and you had not yet heard its report, it will also be included at this point and you will be given an opportunity to acknowledge such recent alarms.

The call will automatically terminate when:

- All linked alarms are acknowledged.
- There is no user touch tone entry after the menu has been recited the configured amount of times.
- The session inactivity time period elapses with no user touch-tone entry.

There are additional key entry options. Some of these are not mentioned in voice prompts in order to maintain simplicity during the call. Note that any of these entries may be made at any time during the call without waiting for any voice prompts.
