# RTU will not go into alarm when it should

For the RTU to Transition into an Unacknowledged Alarm and Dial Out:

- A violation condition must be continuously present for the Alarm Trip Delay period.
- At least one destination must be configured and eligible to receive notification calls.
- For a destination to be configured, there must be a place for the RTU to get acknowledgment, a telephone number for example.
- For a destination to be eligible, it must be linked to the alarming channel.
- Destinations are always linked to all channels with the default settings from the factory, until the user establishes other linking.
- The RTU must not be in the DISARMED state.
- Also, the channel that has the violation must not already be in an acknowledged alarm state, since acknowledged alarm status for a given channel (including power failure) precludes further activity on that channel until that status is cleared.

To clear the acknowledged alarm status of all channels including power failure:

- Starting with the NORMAL light lit, press DISARM/REARM to get the flashing DISARMED indication.
- Then press it again to re-arm the RTU with all acknowledged alarm status cleared.
- Now any violations lasting longer than the Alarm Trip Delay will cause unacknowledged alarms and dialing.
- The corresponding channel number flashing indicates unacknowledged alarm status.
- The same light remaining ON continuously without flashing indicates acknowledged alarm status.

If you do not observe this:

- Press PROGRAM.
- Then press 70 1 ENTER to check the phone number of destination 1.
- Press 80 1 to check the Common Trip Delay.
- If there is a specific channel that you are attempting to create an alarm on, also press 56 <Z> to check for any long single-channel Alarm Trip Delay setting.
- Check the Alarm Violation Criteria configuration for this channel by pressing 52 Z. Make sure it is not set to disabled or status-only, since these settings would not allow an alarm.

Example:

- If the channel Alarm Violation Criteria is configured for Alarm on 1 raw value, you will want to temporarily provide a logic 0 (or a closed circuit if using a physical channel) at its input to trip the alarm.
- You can directly read and verify the Open/Closed status you are applying to physical channels by using the Alarmware™' Check Status, or by using keycode 01 Z.
- Note that the physical channels are by factory default, the first four channel numbers. However, you may have changed these assignments in the course of configuring the RTU.
- You may also use a DC voltmeter to trace your physical input circuit connections. With the RTU turned ON, an Open Circuit to a physical input reads 5 volts DC with respect to the C terminals, or electrical ground. A Closed Circuit reads 0 volts.
