Please note that these specifications apply to the stand-alone juno Net Analogue Addressable panel, 1 or 3 loops
models, equipped with a 2.4 Amp power supply.
Weight: Empty: 5.1 Kg
Including sealed lead acid batteries:2 x 12 V 7 AH I - 10.5 Kg
2 x 12 V 12 AH - 13.5 Kg
Operating temperature: 0ºC to + 40ºC
Relative Humidity: 85% (non-condensing)
Conventional Sounder Circuits: 2 individually programmed. Both circuits current limited and monitored for both open
and short circuit fault conditions. 10k Ohm E.O.L. resistors are used. Maximum current
rating/sounder circuit 400mA @ 28V DC.
Auxiliary Relay Outputs: 2 voltage free changeover relay outputs used for fire indication.
1 voltage free relay output for fault indication. Remains energised (normally closed)
under normal condition and de-energises when any fault condition appears on the
system.
Maximum current rating for each relay contact 1A @ 50 V AC/DC resistive.
Sensor / Loop Circuits: 1, 2 or 3 loop models.
Supports analogue addressable devices over a 2 wire combined power and digital data
transmission loop using the Meter Bus Protocol. Panel to devices communication
achieved using voltage pulses superimposed on DC loop supply. Response from devices
is in the form of 20 mA pulses.
Maximum single loop current loading is 275 mA @ 28V DC. Maximum total current load
for 3 loops is 825mA @ 28V DC.
Maximum recommended loop length is 1 Km with 1.5 mm2 wire cross-section.
Maximum cable capacitance 120 pF/m.
Minimum cable cross-section: 0.5 mm2
Maximum cable cross-section: 2.5 mm2
Primary Supply: 230 V AC +10%/ -15%.

4 Amp - Fast Action 20 mm HRC
Fuse located on electrical mains connector TB, placed on top of the aluminum PSU cover.
Maximum Continuous Primary
Power Supply Rating: 2.4 Amps @ 28 V DC nominal, comprising:
1 Amp max. temperature compensated, short circuit protected, battery charger.
1.4 Amp used for internal electronic circuits and external ancillary circuits: A maximum of
825 mA @ 28V DC is available for loop power (275 mA/loop). Maximum of 100 mA for
internal electronic circuits.
460 mA @ 28V DC for auxiliary power supply output.
Under alarm conditions a maximum of 1 Amp @ 28V DC current available for
conventional sounder circuits.
