WALK TEST.
See Test Mode on page 9. With the LGMRU4x4v2 in test mode, when an
alarm event is received it will be re
-
transmitted back out so that it can be received on a
WALK TEST Instrument.
This is useful for testing the wireless range from the PIR detector.
Do not leave the LGMRU4x4v2 in walk test mode as this uses a lot more air time and
could cause Missing Call error messages on systems with large numbers of detectors.
Sub Net use.
Page 15 shows PIR detectors communicating directly with an LGMRU4x4v2 and also via
repeaters (LGMT4x4)
Where repeaters are used it is necessary to use more sub nets as shown.
