EN: Installation Sheet
Description
The DP721RTA is a conventional multisensor (optical
enhanced by heat) with an interchangeable optical chamber
and local relay output facilities.
The detector uses a combination of detection criteria from both
optical and heat sensors to determine if there is a fire alarm
and automatically resets when the alarm condition is removed.
The DP721RTA is compatible with DB702 and DB702U
mounting bases.
WARNING:
The DP721RTA must not be used in applications
requiring compliance with commercial or residential fire
standards (such as EN 54-5, EN 54-7. EN 54-29, CEA4021, or
EN14604). Always ensure compliance with local codes and
standards.
Installation
Caution:
For general guidelines on system planning, design,
installation, commissioning, use and maintenance, refer to
CEN/TS 54-14 and to local regulations.
To install a detector:
1. Insert the detector head into the mounting base and rotate
it clockwise until it clicks into place.
The detector may be locked into the mounting base if required.
To do this remove the locking tab on the detector before
installation (Figure 1).
Every 700 Series base features a continuity link between LINE
IN (1) and LINE OUT (2) terminals of the conventional detector
circuit. The base is supplied with the link in closed position.
The link is enabled by default allowing you to check the zone
wiring using only the bases. The link will automatically
disconnect when a detector is inserted, allowing the panel to
generate a fault message when the detector is removed.
