If you wish to connect more than one detector per zone then use the latch
facility so that the user can identify which unit has triggered. The panel uses
OP1 programmed as ‘set latch’ to keep the activity LED on the active PIR
glowing. You will need 8 core cable for this facility (see Figure 10).

Wiring Door Contacts
A door contact has two parts: a reed switch housed in a plastic casing, and a
magnet. There are two types of door contact suitable for domestic installation:
Surface and Flush. The Surface contact is fitted on the facing of the door
frame with the magnet fitted in-line on the door. The Flush contact is fitted
into the frame by inserting it into a pre-drilled hole. The magnet is flush and
aligned with the reed switch.
Figure 11 shows shows example connections for typical Surface contacts,
using 4 core cable to wire contacts in series.
