Configuring the Loop Module - Loop M X

3.11.14.1 About Loop M X

The Loop M X is the connection module for an analogue addressable detector loop, as shown in the figure below.

As an option, it is possible to let the customer enter the Loop information in an Excel template and import this information into the configuration program. The loop tab is then completed. For more information, seeIntroduction, page 61.

Figure 63. Loop M X editor box

Description of the fields in the Loop M X editor box:

Address: Enter an address for the Loop M X. Each module in a fire alarm central should have a unique address between 1-125. Default address depends on module type. Please refer to list of modules in sectionAdding Modules, page 24.

Text: A free text field (max 37 characters) describing the Loop M X. This text will be shown in the fault list if a fault is reported from the Loop M X.

3.11.14.2 Loop Tab

The loop tab, as shown in the figure below, shows an overview of the loop connected to this Loop M X.

Figure 64. The Loop tab in the Loop M X editor box

Description of the columns in the loop tab:

No.: A fixed number for the loop on this Loop M X.

Logical: Give the loop a unique number between 1-65534.

Connection: Choose one of the two alternatives by clicking in the Connection column.

Connection alternatives:

• Loop: Select this alternative if the detector loop is double fed, i.e. connected in both ends to the Loop M X.

• Spur: Select this alternative if the detector loop is single fed, i.e. connected in one end only.

Text 1: A free text field (max 37 characters) describing the loop. This text will be shown in the fault list if a fault is reported from the Loop.

Text 2: An additional free text field (max 37 characters) describing the loop.

Shown in the same way as Text 1.

3.11.14.3 Configuring the loop units

Click to display the loop unit as shown in the figure below.

Figure 65. Loop unit list

Description of the columns in the loop unit list:

No.: Address set on each loop unit.

Used: Select if the address is used or not.

Zone: Select which zone the loop unit shall belong to. The zone numbers should be in the interval of 1-65534. The zone number will be displayed at the control panel

if a fire or fault is reported from the loop unit. The zone numbers are freely programmable and may contain loop units from one or several loops.

Logical: Possibility to give the loop unit a unique number between 1-65534. The loop unit will be presented with that number at the control panels. By default, the number is set to the same as the physical address number.

Type: Select type of loop unit by clicking in the Type column.

Table 2. Type alternatives in alphabetical order. (For units marked with '*', see SCI below.)

SCI: Click the check-box in column ‘SCI’ to enable the SCI functions for units with built-in SCI’s (Short Circuit Isolators). See valid SCI-units marked with ‘*’ in the above list under Type.

NOTE!

The check-box can only be used for valid SCI-units. In this case the field surrounding the check-box turns white.

** An exception is “Short circuit isolator” whose check-box always is checked and greyed out. It can not be changed because it is by definition a short circuit

protection.

Text 1: A free text field (max 37 characters) describing the location of the loop unit. This text will be shown in the fault list if a fault is reported from the loop unit.

Text 2: An additional free text field (max 37 characters) describing the location of the loop unit. Shown in the same way as Text 1.

Setup: Select detector sensitivity against fire conditions by clicking in the Setup column.

Setup alternatives:

• High Sense: The detector will have extra high sensitivity.

• Low Sense: The detector will have extra low sensitivity.

• Dual Heat 80C: Alarm temperature will be 80°C.

• Auto Reset: Automatic removal of reported fires.

• Aspiration Box: For detectors with an aspiration box. Reports a fault if the fan stops working.

3.11.14.4 Supervision Tab

Figure 66. The Supervision tab in the editor box

Description of the fields in the Supervision tab:

Secondary backbone channel (B): Disable or enable fault generation from the secondary backbone channel (B). Disable the fault generation if only the primary backbone channel (A) is connected to this module.

3.11.14.5 Advanced Tab

Figure 67. The Advanced tab in the Loop M X editor box

Description of the fields in the Advanced tab:

NS-AOHS: Choose Enable Alarm Blink to make the fire indication LED on all NS-AOHS (including IS versions) on the loop blink – instead of being steady lit when the detectors are activated. This function should be enabled for example when there are many IS detectors and Isolator-A on the loop.

XFire: Click the check-box Disable standby voltage supervision to disable supervision of XFire for the Loop M X.

Supervision of standby voltage on the Basic Backup Signal (XFire) are used in order to verify redundant reporting of the fire condition. This may cause problems when upgrading already installed systems that do not have the XFire signal connected to all modules. The XFire signal is supervised by modules with

XFire-related functionality, i.e. outputs configured for XFIRE activation or inputs configured as conventional zones. The backbone master is responsible for

delivering the standby voltage and must therefore also be connected.
