The Simplicity Micro Fire alarm System has been designed to meet the full requirements of BSEN 5839 part 1 and BSEN 5839 part 6. The fire panel itself complies with EN54 part 2 and EN54 part 4.

The system is an addressable fire alarm fire detection system that is wired as a single loop of up to 2000 metres in length. The system is divided into 4 zones, with each zone capable of containing 8 addressable devices.

Being an addressable system, the Simplicity Micro provides a far greater functionality than a conventional or 2 wire system. In the event of an alarm or a fault, the panel will report the exact address of the device that caused the problem. In addition to this, because the panel has a real time clock, it will record the event with time and date in it`s 2048 entry event log. The panel will also record the user response to the alarm (eg keyswitch on, sounders silenced, panel reset etc), all of which will help the responsible engineer work out the sequence of events before and after the alarm.

In order to minimise system cost, the Simplicity Micro has been designed to use a combination of an addressable sounder (or sounder-flasher) base and a conventional detector. This is the most cost effective way to have a detector & sounder at the same point.

Setting up devices

The address is set on the sounder base, and the sounder base then monitors to see if a detector is fitted. The detector type (optical smoke, or heat) is selected on the sounder base. If the detector is removed, the sounder base reports a fault to the control panel.

If there are several places in the system that need a detector, but do not need a sounder, an Addressable Detector and a common base can be used. These detectors have the address switch on the detector itself. These Detectors will give a pre-alarm alert warning, but are more expensive than the conventional detectors usually used.

The Simplicity Micro uses Addressable call points. These are addressed using a DIP switch beneath the call point`s operating element. The call points are designed to EN54 part 11, and have a Perspex cover to prevent accidental operation. The call point comes with a “snaplatch” anti-tamper clip which can be fitted to help prevent malicious activations.

If there are locations where a sounder is needed WITHOUT a detector, there are a range of stand alone sounders or sounder flashers available for the Simplicity Micro System.

Connecting to external equipment

The panel has built in volt free relays to signal fault & fire. These are rated at 30V, 1A. If additional alarm relays are required, then additional loop I/O interfaces can be added.

These outputs can be used to drive anciliary equipment (eg door magnets, autodiallers or GSM communicators etc), or to signal an alarm condition to another fire alarm panel.

On the Simplicity Micro System, all alarm signals are common. That is an alarm from any detector or call point will operate all sounders & interfaces.

Installing the panel is straightforward. There is just one loop of fireproof cable which links to all the devices. Each device is given a unique address, and the cable returned to the panel & terminated at the connector block.

The panel is configured by simply entering the menu and selecting configure from menu 2. If all devices have been addressed correctly, the panel will now show system normal. If some detectors have been given the same address, the panel will show double address fault. This will need to be rectified before proceeding.

Each device can have a 20 character label to improve the user-friendliness of the system. If an alarm comes, the panel will display the device address (eg 27) and the device label (eg First Floor Room 8).

When all device labels have been entered, the system can be tested. Work through the system testing each call point, and each detector (with smoke test spray, or hot air gun). Also remove each detector 1 at a time, and check that the Simplicity Micro panel reports this as a fault. As a final check create a cable break and check that the panel reports a fault (it may take up to a minute).
