MAF ISOL & TRANSPONDER 0V
A 0V signal is switched back from the transponder test switch and is used for indication purposes at the FIP.
This will indicate as MAF ISOLATED and initiate a common fault. It can also used for external devices to
indicate a fault eg: evac amplifier speaker monitor.
MIMIC DATA & CLOCK
These outputs together with the mimic power terminals are used to serially communicate with the mimic
panels when fitted. EOL resistor is not required on these lines.
AC INPUT
Mains step down transformer output (30VAC) is connected at these terminals. DO NOT connect 240VAC to
these terminals.
BATTERY
The 24V batteries are connected at these terminals. Reverse polarity can cause serious and permanent
damage to the equipment.
DOOR HOLDER AC INPUT
Terminate the door holder AC transformer at these terminals. 24VAC is the only acceptable power source at
this point. DO NOT connect 240VAC at this point.
OUTPUT RELAYS
SBY Normally energised, drops out when power supply (or battery supply) is below specified voltage.
BR1
Brigade 1, defaults as energising on any alarm zone, programmable.
BR2
Brigade 2, defaults as energising on any alarm zone, programmable.
FLT Normally energised, drops out on any fault unless that function is isolated.
NV Normally energised, drops out if the mains is lost.
ISO Energised if any zone is isolated.
GEN1 Energised if any zone goes into alarm
GEN2 Energised if any zone goes into alarm
