Station Grade C, B, or A installation. Normally, a digital
communicator is classified as Grade C and may be classi-
fied Grade B if used with the specified Grade-A Local bell
and bell housing. A UL Central Station Grade-A installation
requires the use of a Napco RM3008 Relay Board and
Ademco 7720 Radio System. Refer to the installation
instructions furnished with each component for respective
installation requirements.
For a UL Commercial Grade-A Police Station Connection,
refer to GRADE-A LOCAL MERCANTILE INSTALLA-
TIONS, which follows. Use the M278 Line-Reversal Moni-
tor to provide basic line security; refer to the instructions
accompanying the M278 for other installation require-

a UL listed intrusion detection unit that is connected to one of the input channels of the Ademco 7720. Relays must be
programmed to trip the Ademco 7720 for alarms on all protective circuits, including tampers, telco phone failure, 24-hour
test timer, transmitter low battery and ac loss. (See PCD3000 External Relay Control screen.) One zone on the
GEM-P1632M, programmed as a 24-Hour Zone, must supervise the radio.
Central Station Grade-A Requirements (Pending)
In addition to Grade-B Requirements (above), one relay on the RM3008 must be programmed to trip the Ademco 7720
