The Edwards FireShield fire alarm family consists of 1, 3, 5 and 10 zone conventional fire alarm control panels, and integrated DACT/Dialer, serial annunciator modules, and serial remote relay modules. All of these components are microprocessor-controlled. The FireShield family is ideal for both new and retrofit installations alike. Edwards FireShield incorporates features designed to simplify installation, operation and maintenance. These include front panel programming, one person walk testing, and selectable IDC and NAC types. In addition, these panels have combination waterflow and supervision IDC. Options for the FireShield panels include serial bus relay modules programmable for common or zone activation, serial bus remote annunciators, city tie and reverse polarity modules, and optional trim rings for semi-flush mounting. An optional fully integrated DACT/Dialer provides 32 character LCD display, event history log, support for Contact ID and SIA DCS 4/2, and upload/download of Panel/DACT configuration, status and event history. FireShield panels are powerful enough to meet the demands of today's installations while leaving plenty of room to grow in the future. All available current may be used for notification appliances, or up to 0.5 amps can be used as auxiliary current. Optional modules and remote indicators mount in boxes with snap-trak or are gangable behind "Decora" switch plates.
