Engineers manuals are not available from this Texecom Website except to bone fide trade engineers.
You will only need an engineer reset if the panel was originally programmed for "engineer reset on tamper" which is sometimes done to protect the installers maintenance liability from interference by the householder.
Simply open the PIR - enter your customer code to silence the tamper alarm- move the PIR - press RESET to clear the tamper (24hr) light.
You may test using walk test Option 06 which is also available in the User Menu. User Manuals are available from www.texe.com
