Instruction Manual

2.0QUICK START

2.1Overview

The Gas Sensor Module has been supplied factory calibrated and ready for immediate installation and operation. An installer familiar with installation and operation of gas detection products can use this section to begin immediate use of the monitor.

2.2 Wiring

Each module requires four-conductor wiring (two wires for power and two wires for the signal).

2.2.1. Model 2050-2060 Series

The Model 2050-2060 series are designed to mount on any indoor vertical surface. Mount the monitor in the desired location.

- The installation must meet any hazard- ous environmental codes for AC/DC elec- trical instrumentation.

2.2.2 Wiring Connection

During warm-up the monitor will, first, cycle through safe/alarm/safe condition at one hertz. This will be followed by a short period of continu- ous alarm before warm-up is completed.

2.2.4 Configuration

The default configuration for each module is to operate with a buzzer and a normally operating open (NOO) relay. The user can change this con- figuration using the jumpers provided. Refer to table 6.2.

Terminal positions on the electronics board are as follows:

Terminal	Function
TB1-1	+ VDC (9 – 24)
TB1-2	GND (0VDC)
TB2-1	Relay NC (Normally Closed) or
	Output to Model 2102 Safe
TB2-2	Relay Common
TB2-3	Relay NO (Normally Open) or
	Output to Model 2102 Alarm
	Table 2.1

2.2.3 Start-up & Operation

To begin operation of the Gas Sensor Module provide 9 - 24 VDC from a regulated power supply such as one of the Sierra Monitor Alarm Panels, 2102-XX. Each time the sensor mod- ule is powered up it will perform a warm-up for 2 - 60 minutes.
