Maintain the performance of electronic security systems
Overview
This NOS sets out the skills, knowledge and understanding for you to maintain the operational performance of electronic security systems, through preventative maintenance, component replacement or adjustment.
This NOS covers the following activities:
1. Carry out preventative maintenance on systems
2. Undertake component replacement or adjustment and subsequent restoration
- Liaise with customers during service visits
Performance criteria

P3 make sure you have full details of the maintenance that you are to carry out on systems
P4 make sure that test equipment is working properly and calibrated where necessary before starting tests
P5 confirm maintenance arrangements with customers (including any reduction of system performance during maintenance) and third parties where necessary, that are mutually acceptable
P6 carry out preventative maintenance at times that are convenient to your customers
P7 carry out required maintenance in line with agreed schedules, approved procedures and codes of practice
P8 confirm that the system meets the specification after maintenance work is completed
P9 record results of tests and inspections accurately using the approved recording methods and formats
P10 comply with relevant health and safety requirements whilst carrying out system maintenance
P11 recognise any changes which may be detrimental to the performance of the transmission, system components and specification
Undertake component replacement or adjustment and subsequent restoration
P12 inform the customer effectively throughout the maintenance process
P13 carry out adjustments and replacements in line with approved procedures and codes of practice
P14 make sure that equipment replacements and adjustments enable systems to meet the specification
P15 calculate the adequacy of installed battery capacity with regards to potential alarm current duration
P16 label replaced components and remove from customers' premises, in line with approved procedures
P17 record details of component replacements and adjustments accurately and fully, using the records format
Liaise with customers during service visits
P18 give customers sufficient warning of any action you are about to take so that potential disruption to their normal activities is minimised*
*
P19 provide customers with details of maintenance carried out
P20 advise customers of any deterioration in system performance
P21 maintain a positive and professional manner with customers at all times
Knowledge and Understanding
You need to know and understand:
Legal and Organisational requirements
K1 current relevant legislation, regulation, standards, codes of practice and guidelines relating to the operation, testing and maintenance of systems
K2 why it is important to dispose of waste debris and surplus material safely and in line with the relevant regulations and codes of practice
K3 your organisation's policy and procedures relevant to working at customer's premises

Carry out preventative maintenance on systems
K5 the tests and maintenance procedures relevant to the specification, transmission and system components
K6 the equipment being tested, including the expected results of the tests you carry out
K7 why it is important to make sure test equipment is working properly, and calibrated where necessary
K8 the purpose of relevant test equipment how to use it and interpret the results
K9 why it is important to record accurate details of test results and maintenance visits, and make them available to the relevant person/s
K10 how to discuss and agree work activities that are mutually acceptable between the customer and you
K11 why you need to identify the presence of electrical supply and how it can be isolated safely
Undertake component replacement or adjustment and subsequent restoration
K12 why, when carrying out adjustments and replacements to systems it is done with the minimum inconvenience to customers
K13 calculate the adequacy of installed battery capacity with regards to potential alarm current duration
K14 what adjustments and replacements you are authorised to make, and how to carry them out
K15 how systems and equipment operate on which adjustments and replacements are carried out
K16 why it is important to record accurate details of adjustments, replacements and maintenance carried out and make them available to the relevant person
K17 how to discuss and negotiate work activities that are mutually acceptable to the customer and yourself
Liaise with customers during service visits
K18 why and how you must carry out maintenance with minimum inconvenience to customers, as well as maintain the safety and security of premises

Glossary
In these National Occupational Standards;
Electronic security systems: a generic term that includes: intruder, fire, cctv, access, remote monitoring systems and other types of protective installations. It also encompasses the integration of existing and new systems.
electrical supply systems: supply to the system components, such as primary and secondary supplies
maintenance: the process of maintaining a system for example (but not exhaustive) measurements, adjustments, calibrations, physical inspections, replacements, tests
specification: the specific detail containing design, installation, commissioning or maintenance requirements
systems: a set of components working together as an interconnecting network. For example (but not exhaustive) new installations; extensions; modifications
tests: For example (but not exhaustive) visual; electrical, operational, induced faults
