P/N 55370172 • REV 05 • ISS 30OCT13 3 / 20
Conventional zone output wiring for standard application is
shown in Figure 3:
1. Conventional zone output
2. Conventional detector
3. 3.9 kΩ, end-of-line resistor
The conventional zone output requires an end-of-line resistor.
Conventional loop impedance/loads for standard installation
are shown in the table below.
Short circuit Zone voltage < 12.5 VDC < 100 Ω
Fire
Zone current > 19.5 mA
Zone voltage > 4 VDC
240 Ω to 620 Ω
Fault 9 mA to 15 mA 1.2 kΩ to 1.4 kΩ
Normal* 3.36 mA to 7 mA 2.7 kΩ to 4.3 kΩ
Open circuit < 2.6 mA > 15 kΩ
* Including all devices and the 3.9 kΩ EOL resistor.
Intrinsically safe installation wiring
Connect the module to the fire panel using the COM2 (positive)
and COM1 (negative) inputs as shown in Figure 2.
Conventional zone output wiring for intrinsically safe
application is shown in Figure 4:
1. Conventional zone output
2. GBX2000 barrier
3. Conventional detector (IS)
4. 5.6 kΩ end-of-line resistor
The total detector current load on the conventional zone after
the GBX2000 barrier must not exceed 1 mA (typically 20 × 670
series IS detectors).
Conventional loop impedance/loads for intrinsically safe
installation are shown in the table below.
Short circuit Zone voltage < 11 VDC < 50 Ω
Fire
Zone current > 19.5 mA
Zone voltage > 12 VDC
240 Ω to 360 Ω
Normal* 3.36 mA to 5.7 mA 3.86 kΩ to 6.2 kΩ
Open circuit < 2.6 mA > 20 kΩ
* Including all devices and the 5.6 kΩ EOL resistor.
Addressing
Each module must be assigned an address from 1 to 128. Use
the rotary dial marked 0 to 12 to set the tens and hundreds part
of the address, and the rotary dial marked 0 to 9 for the
remaining digits. See Figure 5 for sample address settings.
Note: To overcome the mechanical effects of shipping and
storage we recommend that you first rotate each dial counter-
clockwise (to the 0 position) and then clockwise (to the dial’s
maximum position) before setting the required address.
Maintenance
Basic maintenance consists of a yearly inspection. Do not
modify internal wiring or circuitry.
