External fire siren with pressure chamber, red colour ABS housing. In case of fire alarm the siren will be flashing and beeping simultaneously.The double cover is very showy, additionally very durable. The house interior is made of flexible steel. One of the biggest advantages of the siren is the high quality pressure chamber loudspeker. The pressure chamber size is big and the sound pressure level (118 dB).

As needed the tamper switch can be connected on „Tamper” jumper, which might be useful in case of sabotage.

The siren is designed for special and different applications. Can be connected such as fire loop. (Three and four wire connecting or power loss start up.)

1. mode

Operating mode is one of the opportunities requiring only single conductor-pair wireing, but providing, as a result, a lower security.
In such case, connect 24 V power supply to battery charger only, with an adherence to proper polarity. This voltage of 24 V has to be broken by means of a relay in case of fire alarm, and it the siren will set off, powered by rechargeable battery installed therein.

2. mode

In such case, connect 24 V power supply to battery charger only, with an adherence to proper polarity. This voltage of 24 V has to be broken by means of a relay in case of fire alarm, and it the siren will set off, powered by rechargeable battery installed therein.

3. mode

This operating mode makes use of the supervised audible alarm output options offered by more intelligent fire alarm control panels. With the mandatory 24 V power supply to battery charger, the Loop+/- inputs shall be used. Connect the supervised audible alarm output of the control panel here, whereas connect the end-of-line resistor offered for or supplied with the control panel to mark R. Should a battery, loudspeaker or lamp failure occurs, the device will bypass the end-of-line resistor from the loop several times for a period of a couple of secs each time, thereby causing a "Supervised audible alarm output trouble" indication to appear in the control panel. In such case, it is recommended for the installer coming to the site to check first the loop status, because - if it is okay - it is clear that the source of malfunction must be in a siren part.
Relay: It allows for disabling the relay used to break the EOL resistor.

Trouble alarms during operation:

• 4 continuously deepening tone + 4 flashes = faulty battery -
• 4 continuously deepening tone + no flash = faulty bulb - No tone + 4 flashes = faulty loudspeaker
• No tone + 4 flashes = faulty loudspeaker

(The system performs an automatic self-test every 24 hours, and the trouble indications will be issued as a result of such test).

Microprocessor controlled electronic system tests the loudspeaker, bulb, battery in every time.

The siren operates 12 V DC required 4 Ah or 7Ah battery.
