Cancel System Test Relay
On systems supplied after February 1st 2010 using configuration software version 2.0.5 or
higher the user is able to prevent the individual channel repeat relays operating when the
system test pushbutton is pressed.
This feature was previously only available in “View in Advance” mode
This feature is selectable under the sequence tab as shown below and is selectable on a
global basis i.e. individual channel repeat relays can be set to operate on system test or can be
prevented from operating when system test is pressed.
In the example below the repeat relays will not operate during system test.
Dual Repeat Relays
If Dual Repeat Relay outputs are required two channel alarm cards are used with the optional
four channel relay card and the card defaults to:-
• Channel 1 providing outputs on relay R1 and relay R2
• Channel 2 providing outputs on relay R3 and relay R4
Last Card in the System
If the number of alarms in the annunciator means the last alarm card is not fully utilised the
spare relays are automatically assigned as follows
On systems which use two channels, the card defaults to:-
• Channel 1 providing outputs on relay R1 and relay R2
• Channel 2 providing outputs on relay R3 and relay R4
On systems which use 1 channel, the card defaults to:
• Channel providing outputs on relay, R1, R2, R3 and R4
Each relay is equipped with a C/O contact and the user can select the contact state to N/C or
N/O using a 3 way header and 2 way shorting bar located on the relay card.
