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.

Music Server zones can be selected directly in the block for acoustical alarm music server.

Loxone Fire Alarm Function Block

TUTORIAL

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

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

You can also make use of any wired smoke detectors or smoke detectors through the block inputs.
Smoke detectors are connected to the input I and temperature sensors to the input AIt.
If you do not have a Loxone Music Server, and want to use another siren, you can use the Qh output to trigger this.

In the below example, you can see a warning light and a caller service have been connected to the Q1 output. This output is used as a first stage output, before the main siren is triggered.

The first stage alarm (output – Q1) will be switched on after a rising edge on input I, or when the maximum temperature (parameter Tm) has been reached on input AIt. This is normally used as a silent alarm, so the siren will not yet be sounding.

Should the Fire Alarm not me acknowledged before the end of the time specified by Dm then the main alarm (output Q2) and the siren (output Qh) will be switched on.
The alarm can be acknowledged through the app or by a pulse on input C.

Loxone Fire Alarm Function Block With Inputs and Outputs

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.
