Cause

a) The telephone number may be incorrectly programmed.

b) Tone or pulse (the current dialing method) is not compatible with the telephone line on which the Model 400 is installed.

c) Recognition Timeis too long. An alert condition does not remain in effect long enough to become a valid alarm.

d) The FGD 400 is connected to an incompatible telephone line.

Solution

Recheck programming steps.

Switch from the current setting: from tone to pulse, or from pulse to tone.

Reprogram Recognition Time. Set the Recognition Time to the minimum duration required to create a valid alarm. If possible, test the new setting by deliberately creating an alert condition.

The FGD 400 must be connected to a standard (2-wire analog) telephone line, not a digital extension to a phone system. If the unit will not dial out and the factors previously listed have been ruled out, try connecting the unit to a standard residential telephone line.
