Fire sensor A50xxLD
A50 family fire sensor with additional functionality of visual alarm device (Light) and fire siren (sounD) integrated in a single device.
Within the A50 range, multiple combinations of optical, thermal, optical-thermal and UL-certified short-circuit detection are allowed.
To these functionalities can be added the visual alarm device functionality (A50xxL) based on EN 54-23, the fire siren functionality (A50xxD) based on EN 54-3, or both (A50xxLD).
The different models are:
A50SHILD: A50SHI with light and sound
A50SILD: A50SI with light and sound
A50HILD: A50HI with light and sound
A50SHID: A50SHI with sound
A50SID: A50SI with sound
A50HID: A50HI with sound
A50SHIL: A0SHI with light
A50SIL: A50SI with light A50SIL: A50SI with light
A50HIL: A50HI with light
Key features
- Different models with optical, thermal or optical-thermal sensor.
– Built-in short-circuit isolator.
– Low profile socket.
– Possibility of connection to a remote action indicator.
– Easy connection.
– Red and yellow bicolor LED.
– Indication, by means of the red led, of the communication with the control panel (blinking
simple), as well as the alarm status (led on).
– Indication, by means of the yellow LED (single flashing), of the activation of the
short-circuit isolator or the lack of communication with the control panel.
– Signaling of the sensor’s soiling status on the control panel display (the sensor
allows differentiation between rapid signal increases due to alarm and small
slow and sustained increases due to accumulation of dust and dirt).
– Easy-to-install head and socket, interchangeable throughout the A50 range, and
made of white heat-resistant ABS.
– UL certified according to EN 54-5 class A2R, EN 54-7, EN 54-17, EN 54-3 and
EN 54-23 with CE marking according to the European Construction Products Regulation
(EU) No 305/2011.
