Fire Denyer Installation Guide
The Fire Denyer must be installed by a registered electrician
This is the main Fire Denyer Installation Guide. See also the “User Manual” page of this website.
General Installation Notes
- Use the correct tools – especially screwdrivers. Damage can result from using screwdrivers that are too big when terminals are over tightened.
- Use the correct stranded cable for low voltage wiring. Typically 0.4-0.5 square-mm security cable.
- Strip the correct length and twist the strands before inserting wires into terminals.
- The Fire Denyer Controller is usually best installed near the kitchen light switch or somewhere handy for convenient operation.
- A standard single gang flush box will house The Fire Denyer Controller. The backup battery sits on a dwang near the flush box.
- Power supply to The Fire Denyer can be fed from a light switch, but it is best connected to its own supply on the switchboard before RCD supply, maximum 16 amps.
- A smoke detector is usually installed just outside the kitchen area. Additional smoke detectors are installed in all other areas considered at risk, for example bedrooms, lounge and laundry.
- Heat detectors may also be connected if required and would normally be placed closer to the cooking appliance.
- The contactor requires two spaces on the switchboard. If there is no space available it may be housed adjacent to the switchboard in a suitable enclosure.
- Follow the wiring diagram for correct installation. Incorrect wiring may cause damage to the equipment.
The Fire Denyer Controller
Connections are shown in the wiring diagram.
Low voltage wiring connects to the smoke detectors and Flashing Alerters (if installed).
The red loop connection is not required with this model.
After all terminations for the full system are complete, connect the backup battery to The Fire Denyer Controller. The green light. Mains power can be turned on.
Flashing Alerter 4-core wiring is the same as shown below on the earlier model.
Earlier Model – before mid-2024 – for reference only
This model required a wire link between the two end terminals of the 8-way connector.
NOTE: the newer model does not use this wire link.
The earlier model does not have the 2-Amp load fuse.
The white 4-core wire to the right connects to the smoke detectors, the other wire to the flashing alerters.
