Mounting
For correct installation, the Discharge Delay Module must be mounted by bolts or screws
through the mounting holes in the flange on both sides of the Module.
No penetrations are
to be made through the casing of the panel.
The enclosure is rated IP65, so should be
installed in a convenient location, away from where it may be affected by large amounts of
water. The module does not need to be installed adjacent to the fire control panel.

Cabling Requirements
When constructing extension leads the supplied Deutsch Plugs must be used to ensure water-
proof connections are made throughout the installation.
1.
Cut cable to required length and strip outer insulation to approximately 25-30mm.
2.
Strip inner insulation to approximately 6mm and using a Deutsch Crimping tool, fix pins to
the exposed ends of the cable, including the earth where applicable.
3.
Place heat shrink over the end of the cable.
Identify correct socket on plug by the
numbers/letter on the side of the plug and
push through the gasket at the bottom of the
plug until a click is heard and the pin is locked
in place.
4.
Place the locking mechanism inside the plug to ensure pins remain secure. (Male plugs;
locking mechanism is orange. Female plugs; locking mechanism is green).
5.
Using the heat shrink, seal the back of the
plug.
Cables are colour coded for easy identification.
When installing system, cables should be only
connected to the correctly coded cable. Colour
Coding for cables is as follows:

Multiple Discharges & Voltage Limitations
Like the FP-08450/8451 Fire Control Panel, the maximum number of FirePro generators able
to be discharged by a Discharge Delay Module at each output is limited by the voltage of the
main power supply. That is:
Voltage 12vDC
Max = 2 Units
Voltage 24vDC
Max = 4 Units
If a risk area requires a greater number of FirePro generators to be discharged than the
standard panel can provide, Discharge Delay modules can be used. The module will discharge
generators in multiples up to the maximum as above.
If the number of FirePro generators connected to each output is greater than the
maximum, the fire system will not operate.
When multiple FirePro generators are connected to a single output, they
must
be connected
using the FP-08919 Splitter Lead (see 3.7 Connecting Multiple FirePro Generators).
