Installing a combination fire alarm siren is chosen by many contractors for their fire alarm system installation needs. It is used as warning device for fire alarm system. Extended use voltage limits the effect of line voltage drop. It is possible to customize the whistle sound and flash intensity to suit the required application. The light horn kit comes with a wall mount and a plastic cover to cover the wiring, making the product more aesthetically pleasing.

Below are instructions for installation of horns and fire alarm lights in accordance with standards from A – Z of Company P69. Please refer!

Wiring diagram

The light horn uses a common source (2 wires) and the light horn uses a separate source (4 wires).

Switch position to adjust the appropriate buzzer mode

The HEC3  provides continuous or synchronous timed tones in 2400Hz and mechanical tones, alarms and hisses. All tones are easy for professionals to change in the field using switches. The HE3 series has a minimum operating current and has a minimum flash rate of 1Hz regardless of input voltage.

– Set  SWITCH POSITIONS 1 and  2 to the  OFF POSITION position to isolate ( ISOLATED) 2 separate input sources for  horn and flash (HORN AND STROBE ).

– If you want to use the same power supply for fire alarm siren and lights (HORN AND STROBE ), turn SWITCH POSITIONS 1 and 2 to the ON position.

– Turn SWITCH POSITION 6 ON = HIGH DBA (Intensify sound level to “dB”).

– Set  SWITCH POSITION 6 OFF = LOW DBA (Decrease the sound intensity to “dB”).

– Use 4 wires in which 2 wires are used to supply power to the buzzer and 2 wires are used to supply power to the flashing lights (turn switch 1 and  2 to the  OFF position on  HEC24, HEC3-24,  HEC3-12, WHEC24).

NOTE: When using common power for both buzzer and flash light, input and output must be connected to S+; S- correct polarity avoids incorrect connection which can lead to equipment damage.
