
Only TrueAlert appliances and accessories (“Devices”) are allowed on these SLCs. Refer to
Table 4 for a list of compatible TrueAlert devices and to the TrueAlert Device Installation
Instructions for connection details.

Maximum 63 devices or 75 unit loads per channel, whichever comes first. See Table 4 for unit
load details. The maximum number of visuals that can be synchronized on one circuit is 43 for
fixed candela and 46 for multi-candela devices. The maximum resistance between any two visuals
is 30 Ohms.

All wiring is supervised and power limited.

All wiring to be twisted pair – minimum 18 AWG (0.82 mm
2
), maximum 12 AWG (3.31 mm
2
).
If shielded pair is used, the cable shield drain wire from all connected branches and taps must
attach back to the (--) terminal of the circuit. Maximum two wires per terminal position.

Maximum alarm current is 3 A per SLC. Use alarm current for lowest rated appliance nameplate
voltage. Total alarm current for all three SLCs plus all current draw from AUX power and option
cards must not exceed 9 A.

Supervisory current is 0.20 mA per unit load.

Maximum length of all wire segments added together is 10,000 feet (3,048 m) per SLC.
Maximum wire length from panel to any device is 2,500 feet (762 m).

The maximum wiring capacitance is 0.6 uF per channel. If shielded wire is used, you must add the
capacitance of the drain wire to the conductor.

Voltage rating is 24 VDC, 2 V, peak-to-peak ripple maximum.

Maximum of six isolators between any appliance and SLC terminals. Maximum 12 isolators per
SLC. Maximum 30 devices connected directly to any isolator terminal pair.
If notification appliances on a given Class B circuit are to be used for multiple notification zones for
partial evacuation (selective signaling), then the NAC riser must be installed in accordance with the
Survivability From Attack by Fire Requirements in NFPA 2002 ED. Section 6.9.4. One or more of the
following should be used:

2 hour rated cable assembly

A 2 hour rated shaft or enclosure

2 hour rated stairwell in building fully sprinklered in accordance with NFPA 13
The table below shows the maximum wire branch lengths for various alarm loads.
