Electrical Features - Honeywell NOTIFIER UDS-3 User Manual, Installing And Operating Manual

Environmental conditions
 Operating temperature: - 5° C / + 40° C.
 Relative humidity: 10% - 93% (without condensate).
 Storing temperature: -10°C / +50°C
UDS-3 Power
The control panel is powered by mains and, when missing, it can still work thanks to inside fitted batteries.
Mains characteristics are:
 Voltage: single phase 230Vac +10% / -15%
 Frequency: 50 / 60 Hz
 Current: 0.7 Aac
 Protection fuse 2A – FAST (F1 fuse)
N.B.: special care must be taken when installing near electromagnetic powerful sources (ex.
repeaters, radio links, engines etc.)
Power supply unit
Power supply unit has the following outputs:
 27.6 Vdc + 2 % - 10 % 1.25 A ripple max. 300 mV (controlled power for user output, external loads) with
1,35A protection fuse self-restorable (F11 fuse)
 27.6 Vdc / 0,45 A: Battery charges for backup batteries with 2,5A protection fuse self-restorable (F3 fuse)
Battery charger section
 Output voltage: 27,6 Vdc
 Output current: 0,45A ~ 100 mVpp max (temperature compensation=
 Number of batteries that can be connected: 2 * 12 V, 7Ah
Yuasa battery NP7-12 or NP7-12FR (UL94) Faston type – Capacity (20hr) = 12 V 7 Ah –
Dimensions = 151(w) x 65 (d) x 98 (h).
Fiamm battery FG20721 o FGV20721 (UL94) Faston type - Capacity (20hr) = 12 V 7.2 Ah –
Dimensions = 151(w) x 65 (d) x 98 (h).
 Battery-charger section has the following thresholds:
Low-battery: 21.5 Vdc
Unbalanced charge threshold: 3,4 Vdc (difference between the two batteries)
Charged-battery threshold: 20 Vdc
 Quiet current consumption from battery without 230 Vac mains: 100mA without external loads and display
off
 Quiet current consumption from battery without 230 Vac mains: 130mA without external loads and display
on
 Current consumption from battery without 230 Vac mains and with one alarmed zone: 220mA with
discharge on and without external loads and display on
 Current consumption from battery without 230 Vac mains and with two alarmed zones: 300mA with
discharge on and without external loads and display on
