specifications may be required by a particular standard.

22.2 Wiring

All wiring must be in accordance with NEC, ANSI/NFPA 70.

22.3 Transformer

A wire-in transformer should be used. Use the 16.5 VAC Model 320 at 40VA or Model 322 at 100VA.

22.4 End of Line resistor

The DMP Model 310 1K Ω EOL resistor should be used on all 1K Ω EOL fire loops.

22.5 System trouble display

The Status List Display must include at least one keypad that displays system monitor troubles. See

section 10.3 of the 1912XR Programming Manual (LT-0171).

loops. See section 10.4 of the 1912XR Programming Manual (LT-0171).

22.7 Police station phone number

The digital dialer telephone number programmed for communication must not be a police station phone

number, unless that phone number is specifically provided for that purpose.

22.8 System maintenance

Proper installation and regular maintenance by the installing alarm company and frequent testing by the

end user is essential to ensure continuous satisfactory operation of any alarm system. Offering a

maintenance program and acquainting the user with the correct procedure for use and testing of the

system is also the responsibility of the installing alarm company.

22.9 Audible alarm

Fire Type loops should be programmed to activate an audible alarm. The Bell Action for Fire Type loops

should not be programmed as “N”. See section 8.4A in the 1912XR Programming Manual (LT-0171).

Fire loops must be programmed to activate a trouble on open conditions and an alarm on short conditions.

The swinger bypass function must not be used on any fire loops. If a retard is used on a waterflow loop it

cannot exceed 60 seconds and any retard in the waterflow initiating devices must be subtracted from the

60 seconds allowed. See sections 12.7 and 12.17 in the 1912XR Programming Manual (LT-0171). The

retard delay should not be used on a loop with smoke detectors.

The fire key in the upper right corner of the 774 keypad is not intended to replace a manual pull station.

22.12 Style D loops
