An individual on a witness protection scheme might be given several radio triggers with which to
raise an alarm. We would not want any prealarm delay, and so the first two figures are both zero.
We want all progress information turned off so that any criminal who may have visited in order to
intimidate the witness is unaware of the call being made. Normally, personal triggers are configured
to answer an incoming call, but because we do not want a personal radio trigger to answer a call,
reset the inactivity timer or raise an intruder alarm call the next digit is set to 0. We want this
trigger type to use call sequence 3, and we have set the external output to three zeros—to have
no effect.
External output
A trigger type can have three possible effects on the external
output. It can switch the output on (and will have no effect
if the output is already on), it can switch it off (and again will
have no effect if the output is already off) or it can toggle
the output. This means that if the output is on it will be
turned off, whereas if the output is off it will be switched
on. In the example below the number entered for external output
is 2. This means that pressing the key will turn the output on.
Information on making hardwired connections to either the input or output for Lifeline 4000 can
be found in chapter 4 of this guide.
Time on and off.
If the output is turned on then it can also be made to flash (to switch on and
off). The
External Output Time On
figure can be anything from 0 to 9. Entering the digit 9 means
that the output would be on for 1.8 seconds. Entering the digit 3 means that the output would be
on for 0.6 seconds. Even increment of 1 adds 0.2 seconds to the time. The
External Output Time
Off
determines how long the output is off for, before switching back on again. If either of these
figures is set to zero there will be no flashing. In addition, these entries will have no effect if the
key switches the output off (either because it is configured to switch it off or because it is configured
to toggle and the output was previously on).
