Communications (Optional) The inputs are all bipolar so can acceptAC or DC voltages. Repeat Relays RS485 2 or 4 wire, Modbus, ASCII or
Modbus RTU protocol user selectable.
Master and Slave configurations.
Supports bi-directional communications
Ethernet Modbus TCP/IP.
Alarm Management software.
Other protocols available on request. Supply Voltage 24VDC Nominal (19-28VDC) Isolation Each alarm way can have individual repeat
relays. Changeover contact available.
Relay contacts rated at 220VDC
(250VAC) max, 125VDC @ 0.5A, 24VDC @ 2A, resistive.
Two relays per channel can be provided
(Option RL2). Alarm Contacts All customer inputs are optically coupled as
standard and are capable of withstanding
1000V Megger test to ground. Field Contact Voltage Supply Current Per Alarm Point (at 24VDC supply) Quiescent:9mALamps:Small window45mAMedium window90mA

100mA.Standard Power Supplies and DC/DCConverters can be supplied on request. The standard unit is suitable for volt-free
contacts or 24VDC powered inputs. Each
input can be easily set to operate from
either a Normally Open or Normally
Closed field contact. This voltage is distributed through the
annunciator to field contacts, 24VDC is
supplied as standard.Options for 48, 125 and 250V areavailable. The inputs are all bipolar so
can accept AC or DC voltages. Response Time Standard units 22ms Customer defined fixed response time from 1ms to 2s, specified at time of order Adjustable response time typically 5-50ms (Option AD1) First-up Discrimination Better than 5ms Pushbuttons Compliance Both integral and terminals for remotefitting Immunity to EN61000-6-2:2001
