Z15 and Z16 Conventional Sounder Circuit(s) Wiring

Four conventional sounder circuits are provided on the Z15 A-Bus Sounder PCB and two conventional sounder
circuits are provided on the Z16 A-Bus Zone Sounder PCB. Each circuit has a maximum rating of 1A.
IF A FULL COMPLEMENT OF SOUNDERS ARE TO BE USED, THEY MUST BE EQUALLY SPLIT ACROSS
ALL CIRCUITS.
Connect each sounder circuit to the terminals labelled Sounder 1 (Z15 & Z16), Sounder 2 (Z15 & Z16),
Sounder 3 (Z15 only) & Sounder 4 (Z15 only), as shown in Fig.15 below, and terminate earth screens at the
back box earth bar.
Note: ALWAYS make sure the 6k8, EOL resistors (supplied) are fitted across the terminals of the last sounder
on each circuit to allow the wiring to be monitored for open and short circuit faults. If a sounder circuit is
unused, you must still connect the resistor at the PCB terminals.

Z16 Conventional Zone Circuit(s) Wiring

Four conventional zone circuits are provided on the Z16 A-Bus Zone Sounder PCB, each circuit may have a
maximum number of 10 devices fitted.
Connect each zone circuit to the terminals marked Zone 1, Zone 2, Zone 3 & Zone 4, as shown in Fig.16 below,
and terminate earth screens at the back box earth bar.
Note: ALWAYS make sure the four, 0.47µF 50V, end-of-line (EOL) capacitors (supplied) are fitted across the
terminals of the last device on each circuit to allow the wiring to be monitored for open and short circuit faults.
If a zone circuit is unused, you must still connect the capacitor at the PCB terminals.
Detector bases with integral continuity diodes must be used to ensure manual call points remain operational
when a detector head is removed from its base. Manual call points with integral resistors must be used to
prevent a short circuit fault occurring instead of a fire condition when activated.
