Installation Specification
It is the responsibility of the installer to follow Entrotec’s installation and cable specification as well
as ALL relevant wiring regulations. Failure to comply with Entrotec’s installation and cable
specification may result in erratic operation of equipment and could invalidate any warranty.
Installations must comply with the following applicable standards:
•BS 7671: Requirements for electrical installations. IET Wiring Regulations 18th Edition.
•The Electricity at Work Regulations 1989
•ANSI/TIA-568.0-D: Generic Telecommunications Cabling for Customer Premises.
•ANSI/TIA-568.1-D: Commercial Building Telecommunications Cabling Standard.
IET Wiring Regulations 18th Edition: Regulation 444 (MEASURES AGAINST ELECTROMAGNETIC
DISTURBANCES) imposes requirements for segregation of circuits.
IET Wiring Regulations 18th Edition: Regulation 528 (PROXIMITY TO WIRING SYSTEMS TO OTHER
SERVICES) imposes requirements for segregation of door entry / access control circuits (Band I),
230VAC mains circuits (Band II) and other higher voltage circuits.
IET Wiring Regulations 18th Edition: Regulations 541 and 542 impose requirements for earthing
and bonding conductors. Ensure ALL metalwork is bonded to the buildings earth, this includes call
panels, exit switches, cabinets and metal conduit. Ring terminals and earth points are provided on
call panels and cabinets to terminate earth cables, ensure these connections are made.
WARNING - ISOLATION OF ELECTRICAL EQUIPMENT
In compliance with The Electricity at Work Regulations 1989, electrical equipment should be
made dead to prevent danger while work is carried out on or near that equipment. No person

1Cable Specification
The cabling system is based on Unshielded Twisted Pair Category 5e (Cat5e) or Category 6 (Cat6).
The cable must be annealed pure copper, meeting or exceeding the requirements defined in the
standard ANSI/TIA 568 C.2.
Failure to comply with this cable specification may result in erratic operation of equipment.
The specification below shows the minimum cable requirements, allow for extra cabling if
redundancy is required.

FIGURE 5-5 - 1N4007 DIODE FITTED AT LOCK
Entrotec recommend locks with built in suppression. If such a lock is not being used it is ESSENTIAL
to fit suitable suppression, as close to the lock as possible. This prevents back EMF and spikes from
damaging equipment and causing erratic operation.
WARNING
Failure to fit adequate suppression may invalidate any warranty.
NOTE
Entrotec supply 1N4007 diodes.
5.6 Relay Interconnections
The 4 lock connections, by default, are configured for fail open locks (power to hold) e.g., magnetic
locks. This is set with the pre-wired interconnections between the Access Controller and the Lock
Distribution board. To adjust the operation of a lock output for fail closed locks, see section 5.6.1.
