Loop Explorer V4.5 Panel Configuration Utility

There is a new version of Loop Explorer, which has been issued to all registered users.

This version of Loop Explorer allows the Syncro and Syncro Lite control panels to be configured to communicate with the Syncro View repeater.

In addition, it allows for the Hochiki Addressable Remote Indicator (CHQ-ARI) and Multi-Heat Detector (ACB-E) to be configured on Syncro panels.

There are also a number of enhancements to make the process of configuring the Syncro and Solo control panels faster and easier.

For details of Loop Explorer Version 4.5 changes:

This version of Loop Explorer supersedes all previous versions and you should ensure that your computer is updated to this version.

Syncro Panel Upgrade

To allow the Syncro panel to support the Syncro View Repeater and Hochiki CHQ-ARI Addressable Remote Indicator, the Syncro panel firmware will need upgraded to the following versions -

Non-EN version panels currently with firmware versions up to V4.3 -> upgrade to V4.40

BSI Kitemarked panels currently with firmware version V5.2 -> upgrade to V5.30
Download SV530UK:

Non-EN version panels currently networked with BSI Kitemarked panels -> upgrade to EN compatible firmware V5.30

Syncro Lite version panels currently with firmware versions up to V4.3 -> upgrade to V4.40

In addition to the support for the Syncro View, these versions also have an amendment for the Syncro printer operation. This printer amendment means power to the printer is permanently connected and that the Syncro panel does not report a "Printer Fault" when there is no paper in the printer. If the Syncro detects a mains fault or charger fault then the printer power is removed during periods of inactivity, as performed on previous firmware versions.
The purpose of this amendment is to resolve issues whereby some characters as not printed following a period of printer inactivity.
If the Syncro panel is configured with "Graphics Fitted" in Loop Explorer, then the printer operation and fault reporting will revert to the mode of operation used in earlier firmware versions.

 

Suppression of Inductive Loads

When using the fire alarm control panel to supply and switch power to inductive loads, such as magnetic door holders or relays, it is important that these are correctly suppressed.
When inductive loads are de-energised (for example - removing power to the door holders in a fire condition) the action of the electromagnetic field collapsing will induce a reverse voltage in inductive loads. If this is not suppressed, then this reverse voltage will travel into the fire alarm control panel and may cause permanent damage to the electronic circuitry.

Visible symptoms of incorrectly suppressed circuits include:-

Permanent damage to Fuse monitoring circuits (FS Fault) on conventional panels.
Panel occasionally re-initialises following fire activation on microprocessor based panels.
Panel occasionally re-initialises following reset from fire condition on microprocessor based panels.

The most common and effective method used to suppress these loads is by means of a diode connected in parallel with the load. This diode should be connected as close as possible to the load itself and connected with the Cathode (marked with a band) to the load positive connection. A typical diode that would be used is a 1N4004 or similar.

Many relays have these diodes fitted as standard.

Details of correct load connection and suppression is shown in each product manual.
