4.0Panel Check

Ensure that the mains supply has been inspected and tested in accordance with BS5839 Part 1 and the current IEE regulations and that the system is correctly earthed.

4.1Leave all test resistors in place and connect the 230V mains supply.

4.2Switch on. The control panel should react as follows:

(i)The internal buzzer will sound

(ii)The “System on” LED will illuminate

(iii)The LCD will display a time [which needs to be checked)

5.0Panel Configuration – Engineer’s Operating Instructions

NOTE: Please read the panel configuration options before proceeding to commissioning.

5.1Introduction

The functions are intended to allow a complete system to be set up at site level. Three levels of engineer functions are provided. The access system is arranged such that level 1 access only is possible with code 1, levels 1 & 2 with code 2 and all levels with code 3. Level 1 functions are intended for the end user. When the engineer functions are selected, the control panel in most cases still fully operational i.e. an alarm condition will fully activate the panel. The only options which cause the panel not to be fully operational are described later under “Status - disabled” and “Sensor test”.

All engineering menu functions are available after operating the ACCESS CONTROLS key switch and then pressing ENGINEER on the display, followed by input of the appropriate four- digit access code.

If system is left in the engineers mode without controls being pressed, the panel will “time out” to normal operation. Time-out periods vary, depending upon option selected, from 1 to 15 minutes.
