Strip each wire back 1/4 in. (6.5 mm). 2. Press down the white button of the connector. 3. Fully insert the bare wire into the wire cavity of the connector. Note: When inserting the wire, make sure that the wire insulation is not inhibiting the wire from contacting the wire contact points inside the terminal connector. Note: When the wire is properly stripped and inserted in the terminal connector, there should not be any bare wire exposed. 4. Release the white button. 5. Ensure that the wire cannot be easily pulled out of the connector. REV 1.2 [34-2900-0690-7] 8|Page Macurco GBC Manual 3.2.2 Terminal Connection Refer to Figure 3-4 - below for location of different connectors in GBC. REV 1.2 Figure 3-4 GBC Board Diagram [34-2900-0690-7] 9|Page Macurco GBC Manual 3.2.2.1 Main Power Connection Warning: When making connections, make sure the power is off. The GBC offers two power input versions. GBC-X-24: 24 VAC or VDC and GBC-X-120: 120 VAC. Always check the input power type marked on the top of the GBC Main PCBA prior to connecting power. See Figure 3-5 as an example. X Figure 3-5 GBC Board Diagram There are three terminals for Power: Power, Return, Ground. See Figure 3-5. The power connections to the GBC should be size AWG 18 (minimum) for short runs. For longer runs follow recommended power wire gauge guidelines. Match the polarity for power connection, for the low voltage models there is a bridge rectifier, so it is not polarity sensitive. Wire Gauge 18 16 14 Maximum Run Length (feet) (meters) 500 152 800 244 1250 381 Table 3-1 Recommended Wire Gauge Note: Only connect the GBC to Class 2 power supply. Note: It is recommended to use an independent transformer for powering the unit(s) due to possible interferences from other devices on the same power supply. 3.2.2.2 Sensor Connections There are two sensor connections on the GBC. These connections provide power to the respective units and monitor the normally close circuit that controls the GBC. The GBC can support up to four Macurco 6-Series gas detectors (350 mA max) in any combination. The sensors must be wired in series for the normally closed circuit to operate correctly. See Figure 3-6 and Figure 3-7. Note: If not using Sensor Connection 2 with a gas detector a jumper wire or zero-ohm resistor is needed between alarm and 24 V. A zero-ohm resistor is factory populated in the Sensor Connection 2; a jumper wire can be used as in place of the zero-ohm resistor. See Figure 3-6.

The horn/strobe will engage during the same time the onboard relays are set to engage based on the detector set point. See Figure 3-6 and Figure 3-7 3.2.2.4 Relay Connections There are four expansion slots that accept the Macurco Expansion Relay boards. Each Expansion Relay board contains two SPDT, 120/240 VAC, 10 A Max (resistive) relays. Each relay can be wired to be either normally open (NO) or normally closed (NC) depending on the application. There is no polarity for these connections. Each terminal can accommodate a wire size from 12 to 24 AWG. Each relay PCBS are labels NO1, COM1, and NC1 for Relay 1 and NO2, COM2, and NC2 for relay 2. See Figure 3-8. To use relay 1: connect one control wire to the COM1 terminal. For normally open (NO) configuration, connect the other control wire to NO1 terminal. For normally closed (NC) configuration, connect the other control wire to the NC1 terminal. To use relay 2: connect one control wire to the COM2 terminal. For normally open (NO) configuration, connect the other control wire to NO2 terminal. For normally closed (NC) configuration, connect the other control wire to the NC2 terminal. Note: All relays in normal mode are energized and illuminated LEDs on the boards indicate the relays are energized Figure 3-8 Relay PCBA To connect wires to the relay terminals (See section 3.2.1) REV 1.2 [34-2900-0690-7] 13 | P a g e Macurco GBC Manual 4 Operations 4.1 Power up Apply power to the GBC. The Power LED will light up green to indicate the unit is operational. If the unit is powering the detectors, each detector will cycle through its respected power up cycle. The Macurco Gas Detector (EX. CM-XX) cycles through an internal self-test cycle for the first minute that it is powered. The detector will execute the test cycle any time power is dropped and reapplied (i.e., power failure). During the self-test cycle, the detector will display the firmware version number, then count down from 60 to 0 (if the display setting is "On") and finally go into normal operation. The alarm relay will be activated for 10 seconds and the fan relay for 60 seconds during the power-up cycle. The indicator light (LED) will flash green during the self-test cycle. If 4-20 mA setting is set to "EnH", CM-xx will transmit information related to calibration period status via 4-20 mA output during power-up cycle. At the end of the 1-minute cycle, the unit will take its first sample of the air and the indicator light will turn solid green (refer to the specific detector manual for additional information). 4.2 GBC Configuration 4.2.1 GBC Buzzer and Relay Settings There are two jumpers located on the circuit board to control the onboard buzzer and separating the relays via the sensor connections. · Buzzer Jumper (J7): o Jumper position 1 & 2 "Enable". (Default) o Jumper position 2 & 3 "Disable". The Buzzer Jumper controls the buzzer located locally on the front of the enclosure. See Figure 4-1. Figure 4-1 Buzzer Jumper (J7) REV 1.2 [34-2900-0690-7] 14 | P a g e Macurco GBC Manual · Relay Split (J6) o Jumper position 1 & 2 "All". (Default) PCBA Rev 0.1: the "All" setting activates all populated relays 1-8 simultaneously based on activation from sensors connected to Sensor 1 terminal. Note: When the jumper is set to "All" Sensor 2 terminal will NOT engage any of the relays. Only the local buzzer (if jumper is enabled) and external horn/strobe will be engaged during activation from the connected sensors. o Jumper position 2 & 3 "Split". All populated relays 1 through 4 will activate simultaneously based on activation from sensors connected to Sensor 1 terminal. The local buzzer (if jumper is enabled) and external horn/strobe engages. All populated relays 5 through 8 will activate simultaneously based on activation from sensors connected to Sensor 2 terminal. The local buzzer (if jumper is enabled) and external horn/strobe engages.
