In accordance with BS5839 part 1; training on the operation of the Sigma ZXT Extinguishant Control Panel should be provided to the end user as part of the commissioning and handover. In addition to training, the following document provides a convenient
reference point for Control Panel status indications, controls and actions.

Section 2 Control Panel Operation

Manual Only Mode
Manual Only mode will prevent the release of extinguishant being activated by automatic detection devices. Panel will indicate as follows:

• Mode key-switch will be in the Manual position
• Manual LED will be illuminated
• LCD will display panel status as Manual mode.

EXTINGUISHANT RELEASE CAN ONLY BE INSTIGATED BY MANUAL INTERVENTION
Auto Mode
In Auto mode extinguishant release can be instigated by either automatic detection devices or manual intervention:

• Mode key-switch will be in the Auto position
• Auto LED will be illuminated
• LCD will display panel status as Auto & Manual mode.

EXTINGUISHANT RELEASE CAN BE INSTIGATED BY AUTOMATIC DETECTION OR MANUAL INTERVENTION
Zone Fire – Automatic Detection
Automatic detection zones which are not configured to activate the extinguishant release will indicate a general fire condition when activated. A zonal fire will show the following indications:

• Mode Key-switch will be in the Auto position and the accompanying LED will be illuminated
• Fire LED and relevant Zone Fire LED’s will be illuminated
• Panel buzzer will sound urgently
• LCD will display detailed fire information

FOLLOW SITE FIRE PROCEDURE

Zone Fire — Manual mode
In manual mode the ZXT panel will only activate the extinguishant release sequence by manual activation. Zonal fires trig-greed by automatic detection devices will activate a general alarm condition but will not activate the automatic extinguishant release sequence, regardless of panel configuration. Zonal fires in Manual Mode will indicate as follows:

• Mode Key-switch will be in the Manual position and Manual LED will be illuminated
• Fire LED and relevant Zone Fire LED’s will be illuminated
• Panel buzzer will sound urgently
• LCD will display detailed fire information

FOLLOW SITE FIRE PROCEDURE
1st Stage Extinguishant Release — Automatic Activation
Zonal fires can be configured to activate the 1st Stage of an automatic gas release, this is indicated differently to a general fire condition. 1st stage extinguishing release triggered by automatic detection devices will display the fol-lowing indications:

• Mode key-switch will be in Auto position with Auto LED illuminated
• Fire LED and relevant Zone Fire LED’s will flash
• Pre-activated/Activated LED will flash
• Panel buzzer will sound urgently
• LCD will display detailed fire information

1st STAGE OF AUTOMATIC EXTINGUISHANT RELEASE ACTIVATED
Note: Extinguishant
gas will not be released until the 2nd stage extinguishant release activations are met or manual release is operated.
2nd Stage Extinguishant release — Automatic Activation
In automatic mode a combination of zonal fires can be configured to provide co-incidence alarms and activation of the 2nd stage of the extinguishing release sequence — Automatic extinguishant release imminent. A 2nd stage ex- tinguishing release triggered by automatic detection devices will display the following indications:

• Mode key-switch will be in Auto position with Auto LED illuminated
• Fire LED and relevant Zone Fire LED’s will be illuminated
• Pre-activated/Activated LED will be illuminated
• Panel buzzer will sound urgently
• LCD will display extinguishant release countdown timer

2nd STAGE OF AUTOMATIC EXTINGUISHANT RELEASE HAS BEEN ACTIVATED EXTINGUISHANT RELEASE IS IMMINENT EVACUATE AREA IMMEDIATELY AND FOLLOW SITE PROCEDURE

• Fire LED and relevant zone LEDs will be illuminated
• Pre-activated/Activated LED will be illuminated
• Released LED will be illuminated
• Panel buzzer will sound urgently
• LCD will display extinguishant released message after countdown

EXTINGUISHANT HAS BEEN RELEASED DO NOT ENTER RISK AREA FOLLOW SITE PROCEDURES
2nd Stage Extinguishing Release — Manual Activation
2nd stage extinguishing release sequence can be activated at any time through Manual intervention i.e. operation of an Extinguishant Release push-button or Manual Release call point. Manual activation will bypass the 1st Stage Extinguishing Release and activate the 2nd Stage of Extinguishant Release. The panel will indicate as follows:

• Pre-activated/Activated LED will be illuminated
• Manual release LED will be illuminated
•  Panel buzzer will sound urgently
• LCD will display extinguishant release countdown timer

2nd STAGE OF AUTOMATIC EXTINGUISHANT RELEASE HAS BEEN ACTIVATED — EXTINGUISHANT RE-LEASE IS IMMINENT. EVACUATE AREA IMMEDIATELY AND FOLLOW SITE PROCEDURE
Extinguishant Gas Released – Manual
The control panel will indicate confirmation following a successful extinguishant release. If extinguishant release has been activated by automatic detection the panel will indicate as follows:

• Pre-activated/Activated LED will be illuminated
• Manual Release LED will be illuminated
• Released LED will be illuminated
• Panel buzzer will sound urgently
• LCD will display extinguishant released message

EXTINGUISHANT HAS BEEN RELEASED DO NOT ENTER RISK AREA FOLLOW SITE PROCEDURES
Fault Condition
The control panel will indicate active fault conditions as:

• General Fault LED will be illuminated
• Specific fault LED will illuminate i.e. Sounder fault, Power fault etc.
• Buzzer will sound continuously
• LCD screen will display detailed fault information

CALL MAINTENANCE ENGINEER URGENTLY
Note: Active fault conditions can prevent successful operation of the system and must be dealt with quickly
Disablements
During maintenance and testing users can disable functions on the panel to prevent false activations, evacuations etc. Disablements will be indicated as follows:

• General Disablement LED will be illuminated
• Specific Disablement LED will illuminate indicating the function/circuit that is disabled i.e. Zone 1 disabled, Sounder disabled etc.
• Buzzer will sound continuously
• LCD will display the current active state of the zone. Inside the brackets this will be:
  (NORMAL) – No active faults or fires on zone
  (FAULT) – An Active fault exists on the detection zone. Enabling a zone with an active fault will activate the fault condition for that zone.
  (IN FIRE) – An active fire exists on the on the detection zone. Enabling a zone with an active fire condition will activate a fire event for that zone triggering all associated fire cause and effects.

Important safety information!!
The status of detection zones must be checked before enabling any detection zones, it must be ensured the zone status in the brackets shows (NORMAL) before enabling. A panel reset should be completed prior to enabling to clear any active latched alarm or fault conditions. If the zone status remains in fire or fault state after a reset the condition will need to be addressed on the zone itself i.e. clear smoke from detector, repair fault.
VIGILANCE MUST BE MAINTAINED DURING DISABLEMENT PERIODS
Note: Disablements should be cleared as soon as the reason for disablement has completed.
Test Mode
Test mode allows automatic detection devices connected to the zones to be tested without activating the system.
Test mode will be indicated as follows:

• Test LED will be illuminated
•  Zone Test LED for the relevant zone will be illuminated
• Buzzer will sound continuously
• LCD screen will display detailed test information

ENSURE TEST MODE IS CLEARED ONCE TESTING IS COMPLETE
