3.3.4 OPCODE 5
(OPCODE 5 P) FAST MOVE LEVEL SETTING
With opcode digit 5 P the sensitivity of the fast move detector
can be adjusted.
(OPCODE 5 Q AND R)
TURN ON TIME NO-MOVE / NOT-VERTICAL ALARM
AND FAST-MOVE ALARM
Opcode 5 Q and R sets the times (in steps of 5 and 1 seconds
respectively).The transceiver should detect the no-move / not-
vertical alarm or the fast/move alarm status before it goes in to
the pre-alarm status.
(OPCODE DIGITS 5 S, T AND U)
PREALARM TIMERS
Opcode digits 5 S, T and U sets the time a prealarm status
should last before a real alarm is transmitted to the central
control unit as follows :
Opcode 5 S :
prealarm time nomove/not-vertical alarm
(range 0 - 75 secs in steps of 5 seconds)
Opcode 5 T :
prealarm time fastmove alarm
(range 0 - 15 secs in steps of 1 second)
Opcode 5 U :
prealarm time tear-off alarm
(range 0 - 75 secs in steps of 5 seconds)
3.3.5 OPCODE 6
OPCODE 6 P (FAST CHARGE TIME)
The value of this digit (P x 15 mins) determines the time the
transceiver will be charged with a higher current when the
transceiver is placed in a storage rack. After this time the
charging current will revert to a lower charging current (trickle
mode). This function enables the transceiver batteries to be
fully charged in a shorter time (i.e
≤
5hours from empty cells
to fully charged cells).
If a transceiver in the ‘off’ status is placed in the storage rack, it
will always be charged with the higher current for at least 15
minutes.
CAUTION: Never place transceivers with non-recharge-
able batteries in a storage rack with its switch (located in
the battery compartment) placed in the position for
rechargeable batteries.
OPCODE 6 Q (POWER OFF ‘ENABLE/DISABLE’)
The value of this digit determines whether the transceiver car-
rier can switch off the transceiver.
3.4 TABLE OF PILOT TONE FREQUENCIES
With operation codes 2 and 3 the following pilot tones can be
programmed:

* These pilot-tone frequencies do not require hardware
changes.
NOTES:
1. A higher pilot tone frequency will be heard louder in the audio sig-
nal.
2. Modifications to the transceiver’s pilot-tone filters are required
when pilot-tone frequencies other than the default values are
used. Adjustments and/or modifications to the pilot-tone filters of
the system equipment may also be necessary.
The following table shows how the pilot-tone in the trans-
ceiver should be modified if non-standard pilot-tone frequen-
cies are used.
