Electrical Specifications for the Analog
Device Loops
1. Electrical ratings:
SUPERVISORY: 30 V unfiltered full wave
(peak), 30mA max
ALARM:
30 V unfiltered full wave
(peak), 30mA max
(60 devices in alarm)
2. All wiring must be in accordance with Article
760 of NEC or the local building codes. Refer
to Figure 6.
3. Only the list of devices in the
Analog Device
Loops - Compatible Devices
table may be
used. A maximum of 60 devices may be
connected to a single loop.
4. No end of line device is required.
5. Both circuits are power limited per NFPA 70,
NEC. Each detector, or group of detectors,
requires a two-wire circuit of 18 AWG
minimum. For additional wiring information,
refer to the Wiring Specification for MXL,
MXL-IQ and MXLV Systems, P/N 315-092772.
6. Total circuit resistance must not exceed 100
ohms.
Maximum capacitance:
0.4μF line to line
0.8μF line to ground
7. T-tapping is NOT allowed on Class A loops.
8. The jumpers shown in Figure 6 for Class B
wiring are optional. They are not required if the
proper settings are made in CSG-M Rev. 17.01
or higher.
Positive and negative ground fault detected at <40K ohms for TB2 (1-4) and TB3 (1-4).
