INSTALLATION AND MAINTENANCE INTRODUCTIONS

Model AHG2025

Standard detector base

(Ver.2.00)

XIAN FIREALARM ELECTRONICS CO.,LTD

Please read these introductions carefully before the installation so as to use the standard detector base properly.

All installations and connections of the AHG series detector are finished on the AHG base.

First. Features

There are four types of base according to the function realized. Except for the standard base, the rest are preset different kinds of circuit board on the standard base. The base can be fixed inside the embedding box or on the plane directly. Make sure that all the unused terminal screws tightened after the base installation. Make sure the connection between the down-lead and the terminal compact and reliable before installing the detector into the base.

Second. Technical characteristics

1. Operating Voltage

Signal bus voltage: bus 19VDC   Allowable range: 16VDC ~ 22VDC

2. Wire: Signal 2 bus

3. Ambient:

Temperature: -10≧ ~ +50≧

Relative humidity + 95%, no condensation

4. Dimensions: Diameter: 17mm, High: 101mm

5. IP grade: IP32

6. Crust material and color: ABS, Matt White

7. Weight: About 65g

8. Mounting holes: 2 〜 φ5

9. Installation pitch: 50mm ~ 60mm

10. Standard: GB 4716-2005

Third. Appearance and dimensions

Table 1 shows the base terminal

Forth. Installation

This detector base is used together with the detectors produced by our company. The base can be fixed inside the embedding box or on the plane directly. Detector installation diagram is shown in Figure 2. Detector base is wiring as shown in Table 1.








Figure 2 Schematic diagram of detector base installation

1. Wire: Detector 2 bus should use RVS twisted pair whose cross-sectional area is greater than or equals to 1.0mm2, laying through mental pipe or fire-retardant pipe. The total resistance of the bus loop wire should be less than 50Ω, and the total capacitance should be smaller than 0.3μF. The total length of the bus loop wire cannot be longer than 2000m.

2. Figure 3 indicate the wiring method of the AHG2000 series detector when connecting to form a loop














Figure 3 Circle connection method (992 025 as the standard base, 992 026 for the base with isolator)

Notes:

1. Prohibiting the branch access to the root of the Circle

2. Make sure that all the unused terminal screws tightened after the base installation
