For additional help, contact Quest's Technical Support and Service Center.

13.1 Power Up

PROBLEM
▪
Green Power Light is not blinking every second.
SOLUTION
1) Use a voltmeter and verify that the incoming power to the MP1 is between 18 and 65 VDC.
2) Verify input power polarity. If using an A&B feed, make sure both feeds have correct polarity.
3) Replace the MP1

13.2 Communication

PROBLEM
▪
I experienced a communication failure with the TELSEC
SOLUTION
1) Verify you have a physical link by looking at the Green LED on the Ethernet jack. Reconnect or
replace any defective IP/Ethernet cables.
2) Verify the router the TELSEC
3) Verify the IP address has not been changed. Connect to the TELSEC
using the programmed address or try the default address of 192.168.1.31
4) Replace the Ethernet cable.
5) Power cycle the MP1

13.3 Sensor Reading

PROBLEM
▪
I am not receiving data from one of my sensors.
SOLUTION
1) Verify wiring is correct from the sensor to the TELSEC
2) Use a known good sensor and replace the suspected bad sensor.
3) If the known good sensor doesn't work, then disconnect the field wiring from the TELSEC
and connect it directly. If it works now, then correct or replace field wiring.
4) If the known good sensor doesn't read when connected directly to the TELSEC
sensor on another input. Be sure to define the input accordingly.
5) If the input is bad, then either move the sensor to a spare input or replace the unit.

13.4 Control Point Failure

PROBLEM
▪
One of my control points is not turning off.
SOLUTION
1) Verify that the program is correct and has the proper program assigned to the output.
2) Verify the relay on the TELSEC
web server or via SNMP set to the output.
3) Verify the wiring to the control point is correct.
4) Verify the control source voltage (typically an external 24 VAC transformer) is operable and
supplying proper voltage.
