4.2.8. PSR Alarms Connection
For the location of the ALARM RELAY connector, refer to chapter
. The
corresponding cable is part of the delivery:
figure 4-3 PSR alarms cable
Note:
The correct connection of this cable to the dedicated annunciator at the site,
which
must be part of the buil
ding’s fire alarm system
, is the sole
responsibility of the installer.
Note:
The connected dedicated annunciator must be capable of detecting a single
ground or open. End-of-line resistors with a value of 2.2 k Ohm are installed
between the normally open and common relay contacts to support the
supervision.
Note:
The source connected to the ALARM RELAY connector (i.e. the dedicated
annunciator) must be power limited as defined by UL 2524 Chapter 44.1.2
Note:
The length of the connected cable must not exceed 30 meters (98.5 ft).
