1Overview
JBF5174-Ex fire sounder beacon is used in JBF-11SF and JBF50XX fire alarm systems. When a fire occurs in a public place, the control panel sends out an alarm command, and the fire sounder beacon gives out a high-decibel alarm, and the LED flashes. The product is intrinsically safe, and with the explosion-proof barrier, it can be installed indoors in non-residential hazardous areas I and II, for example, the petrochemical zone. The safety barrier must have [Exib Gb] IIC or above certificates.

4Installation
4.1 Installation steps
- Fire sounder beacon adopts unfolded installation.
- After cable laying, fix the base of fire sounder beacon onto wall using M4 screws, pitch of holes 45mm~68mm, as shown in Figure 1.
Figure 1 Appearance and Dimensions
- Before installation, write address to the product by the electronic encoder in the safe area. The address written is in accordance with the address in the project software.
- The two-wire fire bus is connected to Terminals 1, 2 after passing through the safety barrier. The wiring is polarity free.
- Install the fire sounder beacon after the wiring check, to prevent possible damage caused by improper installation.
- Up to 2 fire sounder beacons can be connected to 1 safety barrier as shown in Figure 2.
Figure 2 Wiring
Notes: the parameters of the barrier should follow:
Ui≥Uo, Ii≥Io, Pi≥Po, Ci+Cc≤Co, Li+Lc≤Lo;
Cc, Lc: The cable (or wire) connecting the safety gate to the alarm allows the total distribution of capacitance and inductance. See GB 3836.4-2010 standard for the detailed meaning of other symbols.
4.2 Commissioning
- Write address to fire sounder beacon by electronic encoder, address range: 1~200.
- After successfully writing the address, connect the fire sounder beacon through safety barrier to the control panel to register the device.
- In case of fire, the control panel sends out fire alarm command and the fire sounder beacon flashes and sounds alarm.
- Set different fire sounder beacon working modes by writing special addresses to the product.
