Micro processed and addressable digital sounder (with short-circuit isolator) which is installed as one more element of the  loop

Is a module with a single programming function in terms of the timing and combination of sensors that trigger it. This sounder is configured as a relay acting as sounder

The variant SIRAYL and SIRAY+BSLC additionally emit light signals, where in addition, the SIRAY+BSLC makes it according to EN 54-23 (visual alarm device). The fact that specifically these sounders emitting light does not affect the programming of the control panel. For this reason, these devices are programmed in the control panel as if they were the reference SIRAY

The standard configuration of the sound of the sounder is shown in the bottom figure according to EN 54-3 (acoustic device). The same figure shows the standard configuration of the light signal at the base of the sounder SIRAY+BSLC according to EN 54-23 (visual alarm device)

It is possible to change the tone and light signal selection, but this operation affects the power consumption of the sounder, and therefore, the consumption of the device points. The bottom figure shows a table of equivalence for tone selections (standard 95 dB – 1m and maximum sound intensity 105 dB – 1m) and visual signal (W-2, 4-2, 37, 5). It is possible to calculate the precise calculation with the software of loop elements capacity

Algorithmic addressable heat sensor for fire detection

The A30XTA sensor is based on the physical properties of a NTC.  The variation of the electrical features of the NTC thermistor due to variation of room temperature makes it suitable for a heat sensor

.The A30XTA is capable of registering absolute temperatures (heat sensor) but also temperature rises (rise of heat rate sensor)

The heat rate function allows detect a fire in the first phases of its growth. If it is very slow, the sensor is activated when temperature reaches 55ºC

.Analogue addressable multisensor for fire detection

The A30XHTCO has three different types of sensors: one optical smoke sensor, one heat sensor and one carbon monoxide sensor (CO)

The use of the CO sensor is very valuable for the early detection for some types of fire

As well, the integration with the optical smoke detector inside its algorithm of dynamic processing, give us, as main results, a compact detector very robust facing the false alarms

For complete its benefits, the sensor also has a heat element sets it alarm status when temperature reaches 55ºC
