1.1 Overview
Each 1856 HT SD & 1856 SFT SD unit contains a
door closer, hold open solenoid and a smoke
detector .
The unit can be used as a single installation or as
a series of devices. When the units are wired
together in a run, up to 5 may be interconnected.
Interconnections are accomplished through
terminals #4 and #15 resulting in all alarming
when any one unit senses smoke. In turn, all
associated hold open solenoids are de-energized.
Within any run smoke detecting units it is
permissible to form as many interconnected
series as the total power supply amperage will
allow; but again no more than 5 can be
interconnected.
Any unit with a smoke detector can be connected
to a non-smoke detector unit, or a remote
detector, or both. It can be a single installation
or part of any of the multiple arrangements
described above. A non-smoke detector solenoid
is a slave to the main unit de-energizing when the
main does. Single or group installations can be
connected to the alarm initiation circuit of a
compatible UL/ULC listed fire alarm control 4 or
6 wire configuration panel.
Additional functions are provided to separately
power the hold open solenoids directly from the
alarm control panel or remotely from an alarm
indicator lamp.
