Multi line fire alarm control system: Different from bus fire alarm control system. Multi line fire alarm is a system that lags behind bus alarm. In China, bus systems must be used in situations where fire alarm systems are required by fire safety regulations. If it is not a public place, such as a private villa; Or other non mandatory installation of fire systems, such as transformer stations, communication base stations, etc., can be selected. In addition, according to engineering needs, the supporting functions of multi line systems can also be utilized, such as the need for multi line controllers to link switch type equipment. Below, the manufacturer of the fire alarm system will specifically tell you about it

In foreign countries, it is commonly used in villas, small occasion hotels, hotels, and residential buildings. Therefore, there is relatively high demand in regions such as Southeast Asia and Africa.

1、 Multi line alarm controller - abbreviated as multi line host or multi line controller; Multi line control panel, etc.

A multi line host is considered a hero based on the number of circuits. The market focuses on circuits 4, 8, and 16 (Zone/Zone), as well as circuits 2, 12, and 24. Taking CK1004 (Zone 4), CK1008 (Zone 8), and CK1016 (Zone 16) as examples.

Main features: Power supply voltage AC90-270V, output voltage DC24V, smoke detectors per circuit: 25;

Smoke sensing type: multi line smoke sensing/temperature sensing/smoke temperature composite, or normally open output switch signal smoke sensing

Alarm feedback output: shared every 4 zones.

Backup power: Two 12V/7A lead-acid batteries are required - otherwise, a backup power failure will be reported

Interface display: Each smoke detection circuit has corresponding fault and fire alarm display lights, as well as display lights for main power, backup power, mute (sound and light), mute (main unit), total fault, fire alarm, and alarm output circuits.

Operation buttons: 5 operation buttons: Silence (fire alarm output - sound and light mute), Mute (mute button), Test (self check button), Reset (reset button), Mode (system setting button).

2、 Multi line smoke/temperature/smoke temperature composite: The multi line probe is universal and can be connected to any multi line host. It can also be used in conjunction with a roller shutter door control box. After the probe alarms, the signal will be fed back to the controller by pulling down the voltage. The door lamp is directly connected to the smoke detector base. After the smoke detector alarm, the corresponding door lights will be activated.

Taking smoke sensor YT102 as an example. Power supply: DC9V~DC28V, static current ≤ 60uA, alarm current ≤ 30mA, working temperature: -10 ℃~+50 ℃.

3、 The manual alarm button has a working voltage of DC24V and can be connected in two ways: normally open and normally closed (starting the alarm by inserting or removing the key), as well as in series (all manual alarms participating in series can only start the alarm when they are activated simultaneously) and in parallel. The manual alarm and smoke detector are connected to the same circuit.

4、 Sound and light alarm, working voltage: DC24V, on-site sound and light alarm, connected to the alarm output circuit, playing a role in fire warning and evacuation. Strobe, alarm bell, similar to sound and light.
