Interface Units
&
1. In some instances it may not be possible to functionally test input / output
circuits off an interface unit, such as when it is connected to plant equipment.
2. Ensure the contact rating of interface output circuits are adequate for the
external equipment load requirement.
3. Fit a mains voltage warning label where mains supply is being switched.
Plant equipment
¨
Tests should be carried out following customer consent. It may also be necessary to
obtain third party consent.
¨
All tests on Plant equipment should have been agreed during the project design stage.
Tests
¨
Each interface should be tested for the following:
•
Battery disconnection*
•
Mains supply disconnection*
•
Input line open circuit
•
Input line short circuit
•
Input line detector fire*
•
Input line MCP fire*#
•
Output line open circuit ~
•
Output line short circuit ~
•
Output line operation ~
* - not applicable for the loop powered interface unit, but input tests are applicable for loop
powered interface used as a zone input.
# - a fire from a manual call point or detector connected to a loop powered interface used as a
zone input cannot be differentiated.
~ - the output of the MV interface operates with assigned sector. The output is a set of voltage
free contacts which are not fault monitored.
Interfaced equipment test
¨
The external equipment connected to the system via an interface unit should be tested
as per project specification.
4188-949 issue 3_05/10_Nano Comms inst.
Keyswitches Interface
¨
The keyswitch interface should be configured for correct operation and tested as per
project specification.
¨
Check on operating the keyswitch the adjacent LED is lit.
S-Cube
¨
Depending on the type of S cubed device being tested check to ensure correct output
sound tone, speech message and strobe rate are given.
¨
Each S-Cubed should be tested for correct operation in the event of fire.
¨
The sound levels in the areas should be tested in accordance with the British Standard
requirements and to meet the site specific needs as agreed with the customer.
Repeat indicator panel
Each repeat panel should be tested for the following:
¨
Cancel Buzzer
¨
System event messages and indications
¨
Display of active event log
