in regards to functionality, response time, ability to store alarms, etc.
Up to 1200 m cable can be used for RS485, the 24V supply cable length is mainly

External Presentation Units
1728
External Presentation unit (EPU). Same enclosure as 1736 except that there are
2 more buttons on the 1736 not exist in 1728, namely the Silence Alarm Devices
and Reset buttons also the Acknowledge button is renamed in 1728 to Silence
buzzer. The push buttons are disabled until an alarm is received. The unit is to be
wall mounted. Two compression glands are included.
This unit is intended for pre-warning, co-incidence
alarm presentation. If there are two or more alarms in the system, you can scroll
amongst them but the fire alarms cannot be reset via this unit.
All or selected alarms will be presented in a display (alphanumeric LCD, 2x40
characters), with back-light. An alarm text will be presented together with each
alarm, if programmed in FT1020G3. Furthermore, at least 617 texts can be stored
in the unit for selected fire alarms and will be shown in such a case, instead of the
texts sent out from FT1020G3 for these alarms. These text messages will be
downloaded to the unit via FT1020G3.
Any fault in the system will be presented as "General fault in system", a built-in
buzzer will sound similar to FT1020G3 buzzer and can be silenced.
disablement in the system will be presented as "General disablement in system".
The buzzer can be silenced but the alarm devices in the system e.g. OWS,
sounders, etc. cannot be silenced via this unit. New software versions can be
downloaded directly in to the unit. The unit is powered from FT1020G3 or an
external power supply. The unit must run in S/W mode 1728 – 1587 which has
the highest performance in regards to functionality, response time, ability to store
fire alarms, etc.
The number of units that can be powered via FT1020G3 (or an external power
supply) is dependent on all other units connected to the same CIE / external power
supply.
Up to 1200 m cable length can be used for RS485.
is mainly dependent on the cable size. Refer to chapter "Remote Display Units
