The System Fault and general fault LEDs will light if the configuration memory has not been set or has become corrupted
2.12 Lamp test
Indicators can be lamp tested by holding down the EXIT button for more than 2 seconds.
2.13 Hold condition
Activation of the Hold input on the ECU or at a remotely mounted status unit will cause the Hold Activated indicator to light on
the ECU and on any status units or ancillary boards connected to it.
If the ECU is in the Activated condition and the pre-release timer is running then the Extinguishant release sequence will be
halted and the pulsing, 2nd stage sounders shall change to 1 second on, 2 seconds off.
Release of the Hold input shall re-start the pre-release timer from maximum.
2.14 Turn on Extract output

Note:theextractoutputdoesnotturnoffwhenthemoduleisreset.
2.15 Released condition
The released pressure switch input will be connected to a pressure switch mounted on the Extinguishant cylinder which operates
when the Extinguishant has been released. This will activate the released indicator on the ECU.
If the Extinguishant has been released by mechanical means i.e. the ECU is not in the activated condition, operation of the
released pressure switch input will establish the Released condition.
2.16 Low pressure switch
The low pressure switch input will be connected to a pressure switch on the Extinguishant cylinder which will operate if the
pressure in the cylinder falls below a set point. This will happen after the Extinguishant has been released but may happen
before release through a leak. The fault LED on the ECU and on the detection part will light and the buzzer will sound when this
input is operated.

2.17 Manual only mode
The mode of the system can be toggled between Manual Only and Automatic & Manual by operating the Mode select key switch.
When the ECU is in Manual Only mode, the Extinguishant cannot be released via a serial connection to a Sigma CP fire control
panel or operation of the monitored activation inputs.
The mode can also be changed to manual by the external mode select input or a keyswitch on a status unit. Any mode select
input that is switched to Manual only mode will override a keyswitch switched to Automatic and Manual mode. All inputs must be
switched to Manual and Automatic mode for the ECU to be in Automatic and Manual mode.
2.18 Manual Release
The ECU may be activated by Manual release inputs via the manual release control on the front panel, a remotely mounted
Manual release control connected to the monitored manual release inputs or by a manual release control mounted on a status
unit.
Operation of any of these Manual release controls will immediately activate the ECU and begin the pre-release timer (if the
module is configured to have a time delay for Manual release inputs).
2.19 Abort input
The ECU has the facility for connection of an Abort control. Operation of the Abort input during the pre-release delay time or
before activation will light the Abort indicator on the ECU and the Extinguishant release timer will be cancelled i.e. the
Extinguishant will not be released. The ECU can be immediately reset from this condition.
