3.10 Relay Contacts
Other than the Auxiliary Reset Relay, all Relay
outputs can be configured as either powered and
monitored outputs or Volt-free relay contacts. The
factory default is powered and monitored outputs as
required by EN54-2:1997 & EN12094-1:2003.
3.10.1. First Stage Shutdown (1ST STAGE)
The First Stage Shutdown Relay is energised
when the panel enters the pre-activated condition.
This occurs when the panel is in the AUTOMATIC
& MANUAL mode and a fire occurs on zone 1 or
zone 2. The relay is also energised if the panel
enters the 2
nd
Stage or 3
rd
Stage condition (see
3.10.2 and 3.10.3).
A triple jumper link allows the output to be
powered and monitored (Link ON) or Volt-Free
(Link OFF).
In the Monitored mode, an open or short circuit
fault on the field wiring illuminates the Circuit Fault
LED on the display and the 1
st
Stage Shutdown
Fault LED on the motherboard.
In the Volt-free mode, clean contacts for Pole,
Normally Open & Normally Closed are available,
rated at 1A, 30VDC.
3.10.2. Second Stage Shutdown (2ND
STAGE)
The Second Stage Shutdown Relay is energised
when the panel enters the activated condition.
This occurs when the panel is in the AUTOMATIC
& MANUAL mode and a fire occurs on zone 1 and
zone 2, or the Manual Release is operated (in
Auto or Manual mode). The relay is also energised
if the panel enters the 3
rd
Stage condition (see
3.10.3).
A triple jumper link allows the output to be
powered and monitored (Link ON) or Volt-Free
(Link OFF).
In the Monitored mode, an open or short circuit
fault on the field wiring illuminates the Circuit Fault
LED on the display and the 2
nd
Stage Shutdown
Fault LED on the motherboard.
In the Volt-free mode, clean contacts for Pole,
Normally Open & Normally Closed are available,
rated at 1A, 30VDC.
3.10.3. Third Stage Shutdown (3RD STAGE)
The Third Stage Shutdown Relay is energised
when the pre-discharge delay timer ends & the
actuator circuits are operated. The relay is also
energised if the panel enters the discharged
condition due to operation of the Gas Released
Pressure Switch input (see 3.10.4).
A triple jumper link allows the output to be
powered and monitored (Link ON) or Volt-Free
(Link OFF).
In the Monitored mode, an open or short circuit
fault on the field wiring illuminates the Circuit Fault
LED on the display and the 3
rd
Stage Shutdown
Fault LED on the motherboard.
In the Volt-free mode, clean contacts for Pole,
Normally Open & Normally Closed are available,
rated at 1A, 30VDC.
3.10.4. Gas Discharged (GAS REL SIG)
The Gas Discharged Relay is energised when the
Gas Released Pressure Switch input is activated,
or when the actuator circuits are operated if the
panel is configured for NO PRESSURE SWITCH.
A triple jumper link allows the output to be
powered and monitored (Link ON) or Volt-Free
(Link OFF).
In the Monitored mode, an open or short circuit
fault on the field wiring illuminates the Circuit Fault
LED on the display and the Gas Released signal
Fault LED on the motherboard.
In the Volt-free mode, clean contacts for Pole,
Normally Open & Normally Closed are available,
rated at 1A, 30VDC.
3.10.5. Fire Signal (FIRE SIG)
The Fire Signal Relay is energised when zones 1,
2 or Aux zone detect a fire condition.
A triple jumper link allows the output to be
powered and monitored (Link ON) or Volt-Free
(Link OFF).
In the Monitored mode, an open or short circuit
fault on the field wiring illuminates the Fire Signal
Fault LED on the display.
In the Volt-free mode, clean contacts for Pole,
Normally Open & Normally Closed are available,
rated at 1A, 30VDC.
3.10.6. Fault Signal (FAULT SIG)
The Fault Signal Relay is a fail-safe relay and is
normally energised. It is de-energised for any fault
condition on the panel.
A triple jumper link allows the output to be
powered and monitored (Link ON) or Volt-Free
(Link OFF).
In the Monitored mode, an open or short circuit
fault on the field wiring illuminates the Fault Signal
Fault LED on the display.
In the Volt-free mode, clean contacts for Pole,
Normally Open & Normally Closed are available,
rated at 1A, 30VDC.
3.10.7. Auxiliary Reset (RESET)
The Auxiliary Reset Relay is a single pole change-
over relay and is energised briefly when the panel
is in Fire Reset mode. The relay is energised for
10 seconds. This is to allow ancillary equipment
such as Beam Detectors to be reset. The relay
has no powered and monitored mode and only
volt-free contacts for Pole, Normally Open &
Normally Closed are available, rated at 1A,
30VDC.
