POWERING UP THE PANEL cont.
Loop states are categorized as:
DISCON - Loop open circuited. Loop resistance = infinity
OPEN - Alarm contact open. Loop resistance = 4K4 ohms
CLOSED - Alarm contact closed. Loop resistance = 2K2 ohms
SHORT - Loop short circuited. Loop resistance = 0 ohms
The initialization routine checks the resistance of the loops. If the values returned are outside the
allowed ranges, the zone number of the offending input will be displayed. For example: AREA-
1 3 = 22 indicates the analogue value of 22 from zone 3 is out of range. This is a problem that
must be corrected. Usually a wiring fault or the wrong value of end-of-line resistor is
responsible. If the panel sees a response from zone numbers 101 to 108, ILLEGAL LEM
NUMBER is displayed as these zone addresses are used by Model 3210, 3220, 3230, and 3240
remote keypads. All zones that have allowable values at or near the threshold of acceptability
will be counted and the total will be displayed at the end of this routine. Excessive capacitance
and/or resistance of the cable can also be a problem if more than 2 km of cable are connected or
cable with high capacitance (i.e., shielded cable) is used. Individual responses from the LEM
inputs can be checked in the SINGLE-ZONE MONITOR option of the SERVICE MODE mode
(see page 44). When the correct number of zones is displayed, press the YES key to proceed to
the main program..
L At this time, the display will show 5 DIGIT CODES ?. Press the YES key to accept the
five-digit code option or press the NO key to choose the four-digit code option. See the SET
IDS/OPTIONS function on page 46 for further information. If neither key is pressed within three
seconds, the panel will default to the four-digit code option.
The panel will now show BUSY...RE-SCHEDULING for a few seconds. Next, DATE and
TIME will appear, alternating with some flashing alert messages. If any of the zones are open
(in alarm), then ZONE TYPE ZONE NUMBER OPEN will also be displayed. For infor-
mation on how to acknowledge the alert messages, refer to page 66. This confirms the operation
of the hardware and you may now proceed with programming the control (see page 39).
SOFT START - LEM-LINE RE-INITIALIZATION
If a re-initialization of the LEM line is required, select the RESTART SYSTEM function (see
page 53). To select this function, enter the Service user code and then press the R key (shift 7). A
reboot, or SOFT START, of the panel will be effected. The display will show the usual start-up
messages for a few seconds. From this moment on, the procedure is the same as for a WARM
START (see page 36 above).
