T400 Controller Facilities Manual

667/EB/20200/000 Page 18-2 Issue 9

18.3 PED. AUDIBLE / TACTILE INDICATION (MCE0141 CONTROLLERS ONLY)

Items Required:

K-O-P for Signal Head mounted Audible/Tactile Drive.....667/1/15799/000

K-O-P to add Audio Ind to Push Button Unit ...................667/1/01478/006

Note: If the dimmed supply voltage is 120V, 140V or 160V then the Sonalert Malary

SC628P audible indicator can be used. Only at 160V dimming can the

Bleeptone A.P. Bessom RS/1 18V be used.

It is recommended that all units are the same type on one supply.

The items are connected as shown in the circuit in Figure 18.1 to Figure 18.4. The

connections to the transformer are via single to dual Faston terminals.

Note 1: It is a requirement of Department of Transport that audible signals may only

be used if the pedestrian phase runs with no vehicle phases and it is accompanied by

the Red Lamp Monitoring facility, see sections 19 and 25.

SWITCHED AUDIO/TACTILES

(DRIVE CIRCUIT MUST BE MOUNTED INSIDE THE CONTROLLER)

This facility provides the power unit to supply one group of three Audio/Tactile

Indicators during Pedestrian Green time using a high current output. (This may be

increased to twelve units if additional kits are added). The supply to the

Audible/Tactile can be terminated before the end of the Pedestrian green by utilising a

Controller output.

Note that the ‘Radix System RS250’ Tactile Unit is used if the Tactiles are to be

switched since this provides an input for a steady DC voltage. Unswitched Tactiles can

use the ‘RS251’ Tactile Unit. The ‘RS252’ Tactile Unit can be used in either situations

and is ‘configured’ by the use of a link.

Note that the Pedestrian advice note specifies that irrespective of whether the

pedestrian signal is for sighted or unsighted people, the intergreen given should be the

same. If however the intergreen time for sighted people is reduced below the specified

time and the Tactile HAS to be terminated early to provide safety to the unsighted

people the above method must not be used. A separate phase with its own intergreen

must be used to drive an intersection Tactile.

18.4 SWITCHED MAINS VOLTAGE PEDESTRIAN AUDIBLES (Export Only)

In certain export markets (presently Hong Kong) the Pedestrian audible units are

powered from mains voltage namely the pedestrian phase green man supply and red

man supply. When connected to the green and red man supplies the audio units give

high rate audible clicks as a signal during the green man and lower rate audible clicks

as a signal during the red man. The supplies to these units may be taken via relay

contacts to allow the audio to be switched off at a certain time of day. The required kit

for the switching of these audio units is:
