If manual call points are wired on the same circuit as detectors, then in order to comply with some local
requirements regarding device disconnection monitoring, detector bases should have a Schottky diode fitted
which permits manual call points to continue to operate normally after a detector is removed (see diagram).
Manual call points should have a maximum internal resistance of (470 ~ 680) Ω when activated.
Terminate the wiring for each detector zone in the terminals marked at the control and indicating equipment
and connect the cable screens to earth.
6.8.
Alarm Zones
An alarm output circuit (S1) is provided for non-addressable audio/visual alarm devices. The maximum output
current is 700 mA. All audio/visual alarm devices must be voltage polarity sensitive. Non-polarized alarm
devices will indicate a Fault Condition. The alarm zone circuit is protected against short-circuit. An electronic
fuse will reset when the short circuit is removed and the control and indicating equipment is reset.
Terminate the wiring for each audio/visual alarm device circuit in their respective terminals and the cable
screens connected to earth.
Fit a 100 kΩ resistor (supplied with the control and indicating equipment) to the last audio/visual alarm device
on the alarm zone circuit. If an alarm zone circuit is not used, fit the end-of-line resistor in the control and
indicating equipment alarm output terminals.
An alarm zone circuit wiring layout is shown below. Consult the device installation instructions for device
termination requirements.
6.9.
Ancillary Outputs
Three ancillary outputs are available. Terminate the wiring for each auxiliary output in their respective terminals
and the cable screens connected to earth.
6.9.1. Auxiliary Power
DC 28 V @ 200 mA is available. The output is supervised and short-circuit protected by an electronic fuse,
which resets when the short-circuit is cleared and the panel is reset.
6.9.2. Fire Alarm
The Fire Alarm output provides a voltage-free change-over relay contact output that activates in the Fire Alarm
Condition. The output remains active until the Fire Alarm Condition is reset.
6.9.3. Fault
The Fault output provides a voltage-free normally-closed relay contact output that opens when a Fault
Condition is present.
