The unit must run in S/W mode 1736 – 1587, which has the highest
performance 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 dependent on the cable size. Refer to Table 16 page 167. For more
information, see 1736 Technical Manual.
6.2.2 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, 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 event is received. The unit
is to be wall mounted. Two compression glands are included.
This unit is intended for pre-warning, co-incidence
, fire (and heavy smoke /
heat) 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 same as 1736 (alpha-
numeric LCD, 2x40 characters), with back-light. An alarm text will be presented
with each alarm, if programmed in FT128. Furthermore, at least 617 texts can
be stored in the unit for selected fire alarms and will in such a case be shown,
instead of the texts sent out from FT128 for these alarms. These text messages
will be downloaded to the unit via FT128.
Any fault in the system will be presented as "General fault in system", a built-in
buzzer will sound similar to FT128 buzzer and can be silenced. Any
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 the unit. The unit is power supplied from FT128 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 power supplied via FT128 (or an External
Power Supply) is dependent on all other units connected to the same CIE /
external power supply.
Up to 1200 m cable can be used for RS485. The 24VDC supply cable length is
mainly dependent on the cable size. Refer to Table 16 page 167. For more
information, see External Presentation Unit 1728 Technical description.
