Figure 4 - Measuring Insulation Resistance
The insulation resistance is measured for each conductor, including the shield, against the building earth. The
insulation resistance must be >1 M
Ω.
After this, the cable shield can be connected to the shield connection, see Figure 4 on page 9.
5 EL-KP Keypad
5.1 Overview
EL-KP keypad(s) are used to control and interact with the emergency lighting system. A maximum of 8 keypads
can be connected to the system. The keypads are rear entry only by connection and connect directly to the
CPN serial communication port of the motherboard.
A 4 core cable plus SHEILD is required for the connection of a keypad to the control panel. The keypad can be
powered directly from a local power supply or the control panel’s auxiliary supply. The local power supply must
be double-insulated without need for grounding and must have battery backup. When using any other type of
power supply, the RS485 traffic between the control panel and the keypad must be isolated with the EL-ISOL.
NOTE: When using separate power supplies without the EL-ISOL card, the negative leads of the power
supplies must be connected with the negative leads of the control panel.
