Technical specification
Inputs
•
Input 1: Reset
This input is used to reset the control and indicating equipment.
•
Input 2: Testing of Fire Routing Equipment
This input is used to test the output to the fire routing equipment.
•
Input 3: Disablement of the Fire Routing Equipment
This input is used to disable the fire routing equipment output of the panel. Whilst the FRE is disabled
by this input, it can not be re-enabled by the control panel.
•
Input 4: Disablement of the Fire Protecting Equipment
This input is used to disable the fire protecting equipment output of the panel. Whilst the FRE is
disabled by this input, it can not be re-enabled by the control panel.
•
Input 5: Disablement of Sounders
This input is used to disable the sounders of the control panel. The disablement of sounders from the
Fire Brigade Panel can be re-enabled from the control panel only when the system is not
in Alarm State.

Inputs
The inputs are designed to be actioned in one of two ways, see list below:
First - a change in logic state ie . Switch toggled on / off .
Second - logic pulse ie . nominal state logic high, then logic low > 200mS then return
to logic high .
All inputs are held high via a weak pull up (logic high), the action of short circuiting
any of the five inputs to there respective 0v will result in a logic low .
1. Reset -> Logic pulse
2. FRE relay test -> Logic pulse
3. FPE disable -> Logic state change
4. FRE disable -> Logic state change
5. Acoustic disable -> Pulse logic
