Wiring Details
To maintain the integrity of the ‘type A’ product it is essential that suitable cable glands be
used.
Maximum Loop Current Consumption at 24V
Operating
temperature
–20ºC to +60ºC (T4)
–20°C to +40°C (T5)
The test set can also perform data integrity tests of an entire system.
Note: the test key must remain inserted for at least 2 seconds to ensure the correct CIE
response.
Address Setting
The address of the Manual Call Point is set using the DIL switch. All segments of the switch
are set to 0 or 1, using a small screwdriver or similar tool.
A complete list of address settings is shown in the following table.

Troubleshooting
Before investigating individual units for faults, it is important to check that the system wiring
is fault free. Earth faults on data loops or interface zone wiring may cause communication
errors.
Many fault conditions are the result of simple wiring errors. Check all connections to the
unit. Do not overtighten screws when mounting the backbox.

Commissioning
Manual call points must be installed to comply with the requirements of the ATEX directive
or another applicable codes of regulations. All unused cable entry ports must be sealed
using suitable stopping plugs to give the required level of ingress protection.
Ensure that a glass or deformable element is
fi
tted to each call point before testing. Use the
test key provided to check the operation of each device. An XP95 Test Set, part no. 55000-
870, may be used to carry out functional testing of individual units (from the safe area only).
