Main functions and technical indicators:
1. Alarm input signal
Alarm input signals: general alarm, foam release alarm, fire alarm, machine fault, telephone call, car clock call, engineer safety alarm
The priority is as follows: 1 general alarm, 2 foam release alarm, 3 fire alarm, 4 others. When a higher-level priority alarm occurs, the low-level alarm should be cut off.
If the phone call signal is not confirmed, it should automatically stop within approximately 2 minutes.
2. Signal display color:
(Milk white): Telephone call, car clock call
(Red): fire alarm, foam release alarm
(Green): General alarm
(Amber): Machine malfunction, engineer safety alarm
3. When there is a phone call alarm, the speaker emits a 500Hz intermittent alarm sound, the amber flashing light works, and the 1 # speaker sounds.
When there is a car clock alarm, the speaker emits a 600Hz intermittent alarm sound, the amber turn signal works, and the 1 # horn sounds.
When there is a machine malfunction, the speaker emits an 800Hz/1000Hz transition alarm sound, the amber transition light works, and the 1 # horn sounds.
When there is a universal alarm, the speaker emits a 1000Hz seven short and one long alarm sound, the green indicator light works, and the 2 # speaker sounds.
When there is foam release and water mist alarm, the loudspeaker will emit a 1000Hz continuous FM alarm sound, the red turn light will work, and the 3 # loudspeaker will sound.
When there is a fire alarm, the speaker emits a continuously changing alarm sound of 500-1200Hz, and the 3 # speaker sounds.
When there is a safety alarm for the engineer, the speaker emits an intermittent frequency modulation sound with an equivalent change between 500-1000Hz, the amber turn signal works, and the 1 # horn sounds.
When broadcasting an emergency call, cut off the alarm sound on the light panel (except for the foam alarm sound), and 4 # loudspeaker will send out a broadcast signal.
Alarm sound pressure level: 120dB
4. Power loss alarm: When any circuit loses power, the alarm relay box outputs a pair of closed contacts to disconnect the alarm output.
5. Power supply voltage: 2-way AC220V ± 15%/3A 50/60Hz automatic conversion.
6. All alarm indicator lights are LED
7. Color: MUNSELL 2.5G 7/2: Nameplate: English stainless steel
The junction box should have an appropriate capacity (at least 20%) to allow for the addition of an appropriate number of light panels in the future.
