● LD-8313-bus isolator
When the bus fails, the failure of bus parts and isolate an entire system to ensure that the system of the normal work of the other part, to determine the failure of bus parts. When the failed part of the bus after repair, bus isolators can resume work, will be separated out part into the system, maintenance is simple. LD-8313-bus isolator based on actual number set by the next detector with load capacity of their own, bus isolator with 170mA and 270mA two current, direct-line on the bus, using flexible.

● LD-8319 coding repeaters
LD-8319 coding Repeater is a code module that is used to connect non-encoding detector, occupies only one code point, when the access code relays output circuit of any field device alarm, the alarm relays information to the alarm controller, controller generate alarm signals and display the address of a Repeater. Repeaters can be with the company's production of JTFB-GOF-GST601 noncoding flue gas temperature composite detector, JTY-GF-GST104 noncoding photoelectric smoke detector and JTWB-ZCD-G1 (A) non-encoded electronic differential fixed temperature heat detector, etc. Repeater with output circuit breaker test function, output circuit terminal connection active Terminal LD-8320, when output circuit breaker, coding repeaters will fault information to alert the controller, the controller displays the encoding of the repeaters; when the output circuit with on-site equipment is removed, the encoding will report a failure but a Repeater does not affect the other field devices work correctly. A Repeater can bring many non-encoding detector, you can also mix multiple detectors, but mix the quantity not exceeding 15 only.
Repeaters using four-wire system, the controller needs two alarm signal bus (polarity) and two dc24v (polarity), encoding the relays output polarity with probes used a two-wire connection.
Repeater address coding using electronic encoding encoding range 1 ~ 240 set between, the Hudson Bay Company production of BMQ-1 type electronic encoder for scene changes.
LD-8319 coding repeaters and non-encoding detector series connection, the detector base should add diode 1N5819, and output circuit terminal must add LD-8320 active Terminal. A source terminal can be used when the detector base, that is, the source terminal can be installed non-encoding detector. When a source Terminal is not used as a detector base, should be loaded on the cover. The engineering equipment configuration in order to reduce costs, using Active terminal when the detector base used in active Terminal directly installed non-encoding detector installation mode that reduces the number of the detector base.
The main technical indicators are as follows:
◎ Operating voltage: 24V voltage bus: bus, power supply voltage: DC24V
◎ Monitor current ≤ 0.5mA
◎ Alarm current: 5mA
◎ Wire: and controller uses the promise of signal b bus connection and power supply cord with promise of two-wire connection, and non-encoding detector using polarized two-wire connection
◎ Using environment: temperature:-10 ℃ ~ + 50¡æ £ ¬2 relative humidity: 95%, no condensation
◎ Dimensions: 120mm×80mm×40mm
● LD-8320 active Terminal
In non-coding automatic fire alarm system, the traditional way is through the circuit terminal connection a resistance to maintain the system's normal work, once the entire matching undue alarm system is not functioning, or even produce a false alarm. LD-8320 active Terminal and supporting the use of LD-8319 coding repeaters to replace terminal resistor, when the alarm system output circuit with on-site equipment is removed, the Repeater to LD-8319 coding controllers report fails, but does not affect the other field devices work correctly. Effectively solved the above problem, greatly improving non-coded alarm system reliability.
The main technical indicators are as follows:
◎ Working voltage: DC15V ~ DC28V
◎ Nominal voltage: DC24V
◎ Equivalent resistance: 4.7 k Ω
◎ Using environment: temperature:-10 ℃ ~ + 50¡æ £ ¬2 relative humidity: 95%, no condensation
◎ Dimensions: diameter: 103mm, high: 38mm
