What is a bump test?

A bump test or gas test is the process of testing the sensor and device by applying a known concentration of gas. For a unit to pass a bump test it should respond to the gas applied and read the concentration accurately. The device should then clear to zero when the gas is removed. If the device fails to respond to gas, see the operation manual/ user manual or contact support for troubleshooting. If the device fails to read accurately or does not clear to zero, a calibration may be needed to correct the sensor reading.

Fixed Detectors

Why does the new CM-E1 have a different wire harness than the old one?

The CM-E1 now has an 8-pin wiring harness vs the 6-pin. Please reference the wiring diagram above or in the user manual for the correct alarm and trouble relay configuration back to the alarm control panel.

How often should I test my device?

It is recommended the detectors be bump tested on a regular schedule to ensure the sensor is functional, calibrations may be needed to maintain the sensors accuracy.

What type/size of wire do I use when installing?

Standalone/Analog Applications: 18/4 stranded (preferably shielded)

Modbus Applications: Power: 18/2, Signal: Use at least 3-conductor wire with one twisted pair providing a pair for signal (A & B) and common (COM) connections. For best performance use shielded3-conductor wire with one twisted pair providing a pair for signal (A & B), common (COM) and shield ground (SHD) connections 22 or 24 Guage.

How do I obtain the date of mfg. on my device?

Locate the white sticker on the unit that has 2 sets of numbers. One set of numbers is the part number and the other is the 8 digit date code. Refer to the following image to obtain the date of manufacture.

How do I perform a Calibration on my fixed commercial series detector?

Calibration instructions for all detectors are listed in the products operation manual/ user manual. The user manual can be obtained from the product page on our website.

My detector is showing an error code. What does it mean?

CM-E1 – Flashing amber / end of life – The CM-E1 will flash an Amber LED once the unit has reached its end of life. This indicator can be reset for 24 hours for 30 days. After 30 days the unit will no longer allow the reset and will need to be replaced.

t200 – This error code will display on the Macurco 6 & 12 series devices indicating the sensor has reached its end of life. Depending on the model the sensor can be replaced (TX & OX models) or the device will need to be replaced.

t100 – This error code will display on the Macurco 6 & 12 series devices indicating the sensor is under range or detecting levels less than zero. To clear this code a field calibration will need to be successfully completed on the device.

CCC – This error code will display on the Macurco 6 & 12 series devices when the sensor is over range. Typically, this error will clear once the gas level has returned to levels within range of the sensor.

How do I check the firmware version on my fixed gas detector?

6&12 series – To find the firmware version loaded on your commercial device, disconnect the power either by removing the power terminal from the back of the device or at the power source. When power is reapplied to the unit the display will show the current firmware version prior to starting the warm-up count down.

Control Panels

What do I need to do to complete my DVP Control Panel setup?

Once the DVP control panel is wired and powered on complete these steps to configure your panel:

1) Press the menu button and verify the number of sensors matches the number connected. Troubleshoot any missing sensors.
2) Follow steps outlined in the DVP Quick Start Guide to add the sensors and relays to zones.
3) Test the configuration by either bump testing sensors or performing a 4-20mA test from the sensor.

For further assistance please contact technical support at 844-325-3050 or [email protected]

Which DVP Control Panel should I use for my system?

DVP-120 – The DVP-120 Control Panel is used for smaller (12 sensor or less) systems. This setup utilizes a 4-conductor home run of wire and an analog 4-20mA communication loop.

DVP-120M – The DVP-120M Control Panel is used for larger (13 – 87 sensors) systems. This setup utilizes a Modbus communication loop over a twisted & shielded cable. The panel supports up to 3 communication loops that can be daisy chained from sensor to sensor.

DVP-120B – The DVP-120B Control Panel takes the Modbus communication another step with the addition of BACnet output for logging of the system data. This panel will support up to 99 sensors on two Modbus communication loops both terminating on the TB1 terminal.

DVP-120C – The DVP-120C Control Panel is Approved for Title 24 use in California. This panel utilizes the same hardware as the DVP-120B supporting up to 99 sensors on 2 Modbus communication loops.

How can I test the relays on my DVP Control Panel?

There are a few different ways to test the programming and functionality of the relays on the DVP control panels. Running the 4-20mA test from a connected sensor is one of the simplest and best ways. This test simulates gas being applied to the sensor and changes the output from that sensor, testing the connection to the panel as well as the programming that would control the relay on the panel.

To perform the 4-20mA test follow these steps:
1) Remove the cover from the sensor.
2) Press the Menu button so the display reads “tst”
3) Press the Next/Enter button
4) Press the Menu/Next button so the display reads “42t”
5) Press the Next/Enter button to run the test.

How do I check the firmware version on my DVP Control Panel?

DVP Control Panel – The firmware version of the DVP control panel can be found by cycling power to the panel. When power is applied the display will read the firmware version prior to starting the warmup count down.

Will my DVP Control Panel provide power for the addressable gas detectors?

An external power supply is needed for daisy-chain (Modbus) applications.

Portable Detectors

How do I check the firmware version on my portable gas detector?

PM100 – Pressing the button on the unit seven (7) times will display the firmware version.

PM400 – During power up the display will show the firmware version

Using the PM Link and software suite, the firmware can be viewed and updated on the PM100, PM400 as well as the bump test and calibration stations.

How often should I test my device?

It is recommended to bump test all portable devices prior to each use. If the unit fails a bump test it should not be used until the unit has passed a calibration.
