Figure 10: Device fail output configuration

24.7 Keypad 4-wire bus

The keypad and loop expander 4-wire bus must be run entirely in conduit and remain inside the same room

as the panel, unless an external communication fail indicator is added. A 12 VDC relay may be wired as a

communication failed indicator. Connect the positive side of the indicator to one of the voltage outputs and

the negative side to keypad ground (terminal 10) of the 1912XR. See section 14.2.

In addition to the wiring above, the device fail output must be programmed to activate the appropriate

voltage output. See Section 8.5L of the 1912XR Programming Manual (LT-0171).

24.8 Local Protective Signaling Systems

The DMP Model 866 Indicating Circuit Module must be used on the bell circuit for detection of shorts and

grounds. See sections 26.1 to 26.3 for wiring diagrams. An alphanumeric keypad must be used for local

systems.

24.9 Proprietary Protective Signaling Systems

The total number of panels assigned to one multiplex receiving line of the DMP SCS-1 Receiver system

must not exceed 90. This may be increased to 180 by setting the SNRM option to NO in the SCS-1

Receiver system. This is to allow any report from a 1912XR to be sent to the receiver within 90 seconds.

24.10 Remote Station Protective Signaling Systems

You must provide 60 hours of standby battery. Up to four 12 VDC, 6.5Ah batteries may be used along with

a 16 VAC, 100VA transformer (DMP Model 322). See section 7.6 for standby battery calculations. Two

Radionics Model D127 Reversing Relay Modules provide two reversing polarity telephone connections.

See section 26.5 and the D127 Installation Instruction sheet for wiring details. A DMP Model 893 must be

used to provide two line dialer communication or Type 1 Multiplex communication.

CALIFORNIA STATE FIRE MARSHAL SPECIFICATIONS

25.1 Bell output definition

The bell output of the Model 1912XR must be programmed to operate steady on burglary alarms and

pulsed on fire alarms. See sections 8.4A and 8.4B of the 1912XR Programming Manual (LT-0171).
