If the new device type is rejected (or all new device types are rejected), the panel remembers the programming
for the original devices. The panel will report a fault condition until such time as the correct device types are
reconnected.
Press the

buttons to highlight the required menu option and then press the
✔
button to confirm. The pop-up
window will disappear and the panel will continue with the auto learn process.
If a single device is accepted / rejected and another new device type is subsequently registered, the display will
once again show the pop-up window to accept or reject this device.
3.3.3.5 Double Address
The panel will detect if two devices are configured with the same address.
This may be because there are, for example, two detectors at the same address and the return signal currents
are combined. Additionally, this may be because there are two devices (detector and module) configured for the
same address
– as these devices are in individual address banks (high bank and low bank) the return signal
currents are not combined.
3.3.4 Loop
– Calibrate
Calibrates devices
– The time to calibrate depends on the number of analogue devices connected to the loop. It
can take up to 20 seconds for a full loop.
3.3.5 Loop
– Driver
Displays loop output and input voltages and loop loading.
A diagnostic display with automatic scanning of the loop to find devices with minimum and maximum
communication pulse heights is available.
3.3.6 Loop
– SEQ Address
The loop devices can be assigned an address either by using either the hand-held programmer (VPU100) or by
auto-sequence allocation by the panel.
The auto-sequence option provides a simple means of initially allocating the address of each device.
The auto-sequence function works using the in-built isolators of the devices and by interrogating each device
physically located on the loop (from OUT to IN) in sequence. Addresses are allocated in the sequence 1
– 240
from OUT to IN.
Before commencing:
[1] Ensure that the devices are installed in a loop with no T spur sections.
[2] Check that the loop is continuous. Select View
– Driver to verify the return voltage is present.
[3] On completion, perform an AUTO-LEARN so that the panel learns the devices present and their type.
[4] Verify that the panel has found the necessary devices and the allocated addresses match up to the
expected address / type on the design drawings.
NOTE: It can take up to 15 minutes to scan and address a full loop of 240 devices.
If the last sequenced address does not correspond to the total number of the devices
physically installed on the loop
– check:
The panel shows a loop return voltage.
Disconnect the loop for at least 120 seconds, reconnect and try again.
It is highly recommended that this function be only used on new installations. If a device is to
be added to the loop / replaced, use the hand-held programmer to allocate its address.

WILL CHANGE DEVICE ADDRESS
