Fire and Water Alarm

BASIC FEATURES

You can implement fire and water detection into the Loxone system with little effort using the Fire and Water Alarm function block. In addition, smoke detectors, temperature sensors can also be used for fire detection.

Video

This video explains the features of the Fire Alarm block, and talks you through how to use it within your configuration.

Application

This device is used to alert you if a fire breaks out in your Smart Home or if water leaks.

Loxone’s own products, such as Fire Detectors Air and Water Sensor Air, are automatically detected and used. External products can be connected to the inputs. Temperature sensors can also be used for fire detection.

In addition, music server zones, light control modules and automatic louvre modules can be selected directly in the module for the acoustic alarming.

BASIC SETUP

As with all function blocks, you can find and insert the Fire Alarm block by searching through the “F5” menu. Any Air enabled Smoke Detectors and Temperature Sensors can be integrated with the block by double clicking on the block. After this, simply tick the devices you want to include as sensors for the Fire Alarm. If you have already set up a Loxone Music Server within your configuration, Music Server Zones will also appear in this menu, allowing you to tick the zones you want to play the Fire Alarm siren in.

Loxone Fire Alarm Function Block Inside Linking To Other Blocks

Of course, other temperature sensors or smoke detectors may also be used. Smoke detectors are connected to the input Is and temperature sensors to the input AIt.

Water sensors can be connected to input Iw.

A siren can be connected to output Qh.

In the case of an alarm, the siren sound is played over the Music Server, the lighting flashes and the shading opens fully.

Visualization

The “Last sensors” view shows the last triggered sensors. The number of these can be set in the properties of the block.

The alarm suppression can be activated in the settings via the visualization. With the help of the alarm suppression you can carry out service work with fire detectors / water sensors / etc without the alarm going off.

Programming example

In this example, a warning light and a caller were also linked to Q1. The caller informs you about the alarm by telephone.

As soon as a smoke detector triggers or a temperature sensor exceeds the maximum temperature (parameter Tm), the pre-alarm is started and output Q1 is activated. The pre-alarm is a silent alarm, which means that the siren is not switched on at this time. If the alarm is not acknowledged via the app or a pulse to input C within a certain time (parameter Dm), the main alarm will start. The main alarm also activates the input Q2 as well as the siren.

 

INPUTS, PARAMETERS, OUTPUTS

INPUTS

CAcknowledge AlarmAcknowledge the alarm on the rising edge.
CHSilence sirenTurns off output Qh to silence the siren, alarm outputs Q1 & Q2 stay on.
ISmoke alarm inputDigital Input for wired smoke detectors.
AltTemperature inputDigital Input for wired temperature sensors.

PARAMETERS

DDelay of main alarmDelay before the main alarm (Q2) starts (in seconds).
TmMaximum temperatureThe alarm activates when any temperature sensor used with the block reaches this value.
DmMaximum duration of the alarmMaximum duration of the alarm in seconds. Set to 0 for unlimited.
CaAutomatic acknowledgementWhen Ca = 1, the main alarm will be automatically acknowledged at the end of the timer Dm
MsService modeService mode is activated when this parameter is set to 1. Only Qt will be activated as an alarm test.

OUTPUTS

Q1Digital output – first stage alarmOutput ON as soon input I is triggered, or AIt exceeds maximum set by parameter Tm
Q2Digital output – main alarmOutput ON only after input I is triggered, or AIt exceeds maximum set by parameter Tm, and a delay set by parameter D.
QhDigital output – sirenOutput for connecting a siren.
AQAnalogue output – Number of active detectorsAnalogue output defining how many detectors are currently active
QtDigital output – test alarmOutput for test alarm (service mode) – will be ON only when the parameter Ms is ON
TQText output last active detectorProvides the name of the last active detector.
