3.5.2 Loop Driver Cards
Adding loop driver cards to the base unit expands the system. There are expansion slots for one
loop driver card in the ZX1Se, up to two loop driver cards in ZX2Se (designated Loop 1 and Loop
2) and up to five loop drivers in ZX5Se (designated Loop 1 to Loop 5). The ZX10Se can be fitted
with up to ten loop drivers – up to five per ZX5Se panel.
Note that the first loop, designated ‘loop 1’ is situated at the top right-hand side of the base card.
Each card is secured with the four M3x6 screws supplied.

4-way header
When removing a loop driver, the latch on
the 4-way header must be pushed away
from the connector before attempting to
pull the connector out.
Check that both the 10-way and 4-way
connectors are correctly aligned and
pushed fully home onto the pin headers.
The ZX2Se and ZX5Se Fire Alarm Control
Panels only supports one manufacturer
loop type at a time.
DO NOT install loop drivers of different
types in the panel.

Selection
The installation of each loop driver card requires the setting of a link, or links, to adjust the loop
driver power supply for compliance with the different manufacturers’ protocols.
3.5.2.1.1 ZX1Se / ZX2Se Jumper Settings
The loop voltage for each loop driver type is selected using the jumper link J1. The following
