Operational Safety Notices
1.1
Installer
Installers must be suitably trained and qualified for electrical work, according to the laws
and local codes for the locality and country where the unit will be installed.
This unit must only be installed by personnel that have been trained by Telensa or their
representatives to carry out this work.
1.2
Power Supply
In the case of field installation, the supply voltage present on the luminaire NEMA socket is
hazardous and all necessary precautions must be taken to ensure the safety of the
installer. Isolate the supply to the NEMA socket before removing an old photocontrol, and
installing the Telecell.

Product function
The Telecell is a radio controlled device and will only function as part of a Telensa Central
Management System (CMS). Telecells are assigned to a specific CMS and cannot be
transferred to another CMS without being re-assigned by Telensa.
The Telecell operating program is set by the CMS and dusk/dawn lamp switching is
remote controlled over the radio link by the associated CMS base stations. Typical
maximum radio link distances are 2-3km in a urban areas and 3-10km in rural areas,
depending on the terrain.

Telecell Variants
There are two key variants of the Telecell 2 model; dimming control and standard / nondimming control. Dimming control products are identified by the text “0-10V & DALI” on the
product label.
Telecell products are built and supplied to either the EU or US standards:
US product part numbers start with T2A…
The products are supplied with NEMA pin connections for insertion into the photocell
socket on top of a luminaire.

Notes on Dimming Control Outputs
These notes apply to products with the integrated dimming control function:

Suitable for use with dimmable ballasts with an isolated or non-isolated control
input

DALI or 0-10V control mode is auto-selected by the Telecell by communicating with
the connected ballast.

0-10V control requires the normally fitted internal pull-up resistor in the ballast

DALI control includes the DALI supply function within the Telecell and is suitable for
controlling from one to three dimmable ballasts.

Installation Instructions
Instructions for the installation of each of the different variants of Telecell are given below.
Figure 2 shows a wiring diagram for a standard lamp with a non-dimmable ballast. Figure 3
shows dimming control using a dimmable ballast.
Once installed and power is applied then the Telecell will automatically switch on to apply
power to the lamp as an installation test. After one minute the lamp will be switched off and
the Telecell will search and lock to the radio control signals from the system base stations.
5.1
Dimming Control NEMA Telecell T2A1N
A dimming control Telecell will ONLY control a lamp that incorporates a 5 or 7 pin
NEMA socket compliant with ANSI C136.41 2013.
Insert unit into NEMA socket on street light ensuring the largest tab on the unit places into
the largest tab recess on the NEMA socket on the street light. Turn by hand clockwise
typically 30 degrees to lock in place.
5.2
Standard (Non-dimming) NEMA Telecell T2A1N
Insert unit into NEMA socket on street light ensuring the largest tab on the unit places into
the largest tab recess on the NEMA socket on the street light. Turn by hand clockwise
typically 30 degrees to lock in place.
5.3
Post Top Telecell Type T2A1P
This product is for installation within the photocontrol cavity of post top mounted heritage
style lanterns. A separate “twig” style antenna must be installed with this Telecell, which
has no internal antenna.
First, do a trial installation of the Telecell in the lantern socket to check the location of the
Telecell antenna socket. The antenna cable will have to reach to this socket. Mark a
suitable location for the antenna on the outside of the luminaire and unplug and remove
the Telecell.
Drill a half inch (12.5mm) hole in the luminaire case to mount the antenna and fit it in
place. When fitting the antenna use all the waterproofing gaskets as provided and ensure
that the metal grounding teeth on the antenna base make contact inside the luminaire
case.
Fit the Telecell to its socket then attach the antenna lead connector to the Telecell antenna
connector. Tighten by hand gently, there is no need for a high torque. If necessary, use a
5/16in wrench. The maximum torque is 3in-lbf.
Use only antennas supplied by Telensa for this application, see Table 1.
5.4
Two-part Telecell Type T2A1U
This product is intended for installation within a luminaire that has no NEMA socket, or
insufficient space for fitting a NEMA socket. An external antenna must be fitted for the
Telecell to function.

Installation Instructions

When safe, open the luminaire and install the two-part Telecell as follows:
First drill a half-inch (12.5mm) hole in a suitable flat area of the luminaire wall to fit the
external antenna, making sure there is clearance inside the luminaire for the antenna
cabling. When fitting the antenna use all the waterproofing gaskets as provided and ensure
that the metal grounding teeth on the antenna base make contact inside the luminaire
case.
Find a suitable location for the T2A1U Telecell inside the luminaire and fix it in place. Wire
the Telecell following the wiring diagram in Figure 2 or Figure 3 of this document. Next
attach the Telecell antenna lead to the antenna connector. Tighten by hand gently, there is
no need for a high torque. If necessary, use a 5/16in wrench. The maximum connector
torque is 3in-lbf.
Use only antennas supplied by Telensa for this application, see Table 1.
5.5
External Antennas
Use only those antennas supplied by Telensa for use with the T2A1P or T2A1U, see Table
1 for Telensa antenna part numbers.

Installation Logging
The telecell ID number, the OSID, is bar coded and located underside the unit. This OSID
must be recorded with the ID or geographic co-ordinates of the lamp under control and
recorded in the CMS database. There are a number of different methods to achieve this
and installers will be trained with the appropriate method for their system.
