Wiring Tables and Information
Table 3: Initiating Circuit Wiring
Table 4: Indicating Circuit Wiring
Four-Wire Smoke Power (regulated)
4-wire smoke power is provided for 4-wire smoke detectors. This filtered supply is supervised therefore a short will
disconnect the power through the relay until the “RESET” key is pressed. A trouble signal will be generated once
there is a short. This supply is rated at 22.3VDC regulated/300mA max/1V voltage drop maximum.
Supervised Auxiliary Power (regulated)
Supervised auxiliary power is used to power the remote annunciators and smart relay modules. This filtered circuit
is supervised therefore a short will disconnect the power through the relay until the “RESET” key is pressed. A
trouble signal will be generated once there is a short.This supply is rated at 22.3VDC regulated/500mA max/1V
voltage drop maximum.
Auxiliary Power (unfiltered)
This unfiltered supply is not supervised. This supply is rated at 24VDC FWR/1.7A max. If there is a short on this
circuit, the auxiliary power does not recover automatically when the short is removed. The main power must be
disconnected, then reconnected and the panel reset to re-establish the auxiliary power supply.

Notes:
• For Class A wiring the resistance in ohms is multiplied by two.
• Maximum voltage drop should not exceed 1.8 volts.
Notes:
• For Class A the maximum
wiring run to the last device is
divided by two.
• Maximum loop resistance
should not exceed 100 ohms.
• Maximum capacitance of
0.5uF total on each initiating
circuit.
