Remote Annunciation; Audible Alarms - Siemens System 3 Manual

4. REMOTE ANNUNCIATION

RL REMOTE ALARM LAMPS SERIES
This series of remote alarm lamps was
designed to offer fast and convenient
identification of any detectors that release
alarms within concealed spaces such as
staterooms, store rooms, lockers, etc. The
RL-30 and RL-40 models are used as remote
individual detector alarm lamps on round or
rectangular switch boxes, respectively. The
RL-6 can accommodate up to four detectors
with one common remote indication. (See Spec
Sheet Catalog No. 8011 and No. 8013.)

5. AUDIBLE ALARMS

ALARM LOCATIONS AND
REQUIREMENTS
Ten inch bells are required to sound in the
following locations when any alarm initiating
device is actuated.
1. Alarm bell must always sound on the bridge
regardless of which zone is in alarm.
2. Alarm bells must sound in the engine room,
machinery spaces, and the control room
when the alarm is initiated in any of these
spaces. In case the control room might be
unattended at the time of alarm, bells must
also be installed in the passageways and
lounge areas of the licensed engineer's
quarters.
3. If an alarm is not acknowledged (silenced or
reset) at the control panel within 2 minutes,
the control panel must automatically cause
the General Alarm to sound.
Section III — Equipment Descriptions and Functions
RLP REMOTE LAMP PANELS SERIES
The RLP-4, -8, and -12, with 4, 8, and 12
lamps, respectively, serve the same purpose
as the individual remote alarm lamps, except
that they are mounted on a common panel.
(See Spec Sheet Catalog No. 8012.)
NOTE: If it should be necessary to
supplement the 10 inch bell audible output in
high noise background areas with horns,
sirens, strobes, flashing or rotating lights,
the wiring to such supplementary alarm
devices does not have to be supervised.
However, audible alarms other than bells
must always be accompanied by lights or
strobes.
BT-F and BT-SS Bells
The BT-F and BT-SS are vibrating and single
stroke 10-inch bells. (See Spec. Sheet
Catalog No. 2537.)
