Introduction
1.1
General Information
The FP-08850 Discharge Delay Module provides the FP-08450 or FP-08451 Fire Control Panel
to activate additional FirePro generators, or delay the activation sequence of the fire system
via programmable delay. The Discharge circuits are monitored.
1.2
Discharging Additional FirePro Generators
The number of FirePro generators a FP-08450 or FP-0451 Fire Control Panel can discharge
depends on the voltage from the available power supply.
12vDC
Max 2 x FirePro Generators
24vDC
Max 4 x Firepro Generators
Where risk requires a more FirePro Units to be used, or a delay in the activation. The Discharge
Delay module must be used. The module will activate FirePro generators sequentially in
multiples of the quantities as per the available power supply.
1.3
Delaying Discharge
The discharge delay function includes a programmable timer that can be used to delay the
activation of the FirePro generators until suitable. This can be set to account for vehicle or
site specific conditions, for example; large areas of leakage, time allowance for evacuation, or
increased hold time in the risk area.

Design Considerations
3.1
Normal Output
The
“Normal” output
(marked yellow 1) activates any connected FirePro generators
immediately when the activation sequence begins - it is NOT affected by the delay timer.
Where a system requires the use of only the delayed discharge circuit, the supplied
3k3Ω End
-
of-line resistor
must
be installed on the
“Normal” output
, or a fault will be displayed.
3.2
Discharge Delayed Output
The “Discharge Delay” output (marked yellow 2) ac
tivates any connected FirePro generators
as per the programming to the delay timer. The delay timer initiates when the control panel
begins the activation sequence. When the programmed time is reached, the connected FirePro
generators will discharge.
