1.3 Turning ON (arming) the System

The green

Status light must be on steady and no zone lights are displayed on the DS7443 or DS7445 keypad. The DS7447 display must read

“Ready To Arm” in order to arm the system with one of these commands.

If the green

Status light is not on, or zone lights are displayed on the DS7443 or DS7445 keypad, or if the DS7447's display is reading “Not

Ready,” then see Section 1.7 Force Arming or Section 1.9 Zone Bypass for other ways to arm the system.

NOTE: In commercial burglar applications for U. L. Listed Requirements, a ring-back indication and bell test should be heard after arming

(closing). If not heard, call for service.

NOTE: If the system has invisible zones that are not ready, they will be displayed during the arming sequence. The display of invisible zones

will remain on until the zone is cleared or bypassed.

The chart below explains the four normal ways of arming the system.

The Emergency Alarm Keys [A], [B], and [C] may generate Fire, Special Emergency, and Panic Alarms if programmed by the installer. Ask your

installing company to explain the function of these keys.

When using the Emergency Alarm Keys, they must be pressed for two seconds to generate an alarm.

NOTE: If the Emergency Alarm keys are to be used, they should be labeled to signify their functions.

The “A” key should be labeled as the Fire key. This is the only key that may be designated as the Fire key.

The “B” key should be labeled as the Help key.

The “C” key should be labeled as the Panic key.

Use the Disarming Command Sequence to cancel or silence these alarms.

1.22 Fire Safety

This fire alarm system can provide early warning of a developing fire. Such a system, however, does not ensure protection against property

damage or loss of life resulting from a fire. Any fire alarm system may fail to warn for any number of reasons (e.g. smoke not reaching a detector

that is behind a closed door).

When considering detectors for residential applications, refer to NFPA Standard 72, “The National Fire Alarm Code.” This standard is available

at a nominal cost from: The National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.

If Installed in Family Residences

Adherence to the NFPA Standard 72 can lead to reasonable fire safety when the following items are practiced:

• Minimize hazards: Avoid the three traditional fire killers: smoking in bed, leaving children home alone, and cleaning with flammable liquids.

• Provide a fire warning system: Most fire deaths occur in the home, the majority, during sleeping hours. The minimum level of protection

requires smoke detectors to be installed outside of each separate sleeping area and on each additional story of the dwelling.

For added early warning protection, it is recommended that detectors be installed in all separated areas including the basement, bedrooms,

dining room, utility room, furnace room, and hallways.
