10 Amp Booster Power Supply
Description The 10 Amp and 6.5 Amp Booster Power Supplies (BPS) are designed to extend a fire alarm ’s signaling capacity. The Booster can be connected to existing Class A or Class B Notification Appliance Circuits (NACs) or activated via Signature Series modules. There are four independent 3.0 Amp NAC circuits supervised in a non-alarm condition. The Booster has a trouble relay that operates on any Booster trouble. The Booster contains a battery charger capable of charging up to two 10 amp hour, 12 V batteries to supply a total of 24 Vdc.

Wiring the Booster Power Supply Wiring placement To avoid noise, keep input wiring isolated from high current output and power limited wiring. Separate high current input/output from low current. Separate power limited from nonpower limited wiring. Wiring within the cabinet should be routed around the cabinet, not across the printed circuit board.

Wiring for internal booster activation of NACs You can turn on the Booster Power Supply using the batteries rather than using one of NAC/AUX outputs. This leaves all four NAC outputs available to power NAC devices. The Signature loop controller issues commands to activate the NACs during fire alarm conditions. In this application, a Signature module receives the command and draws power from batteries wired to the Booster. The Signature module routes the battery power into the Booster's Sense 1 terminal. When the Booster receives power from the Signature module, it activates the NACs. [Battery_booster_activation.CDR]

Note: No "T" tapping
permitted.
The NAC cable must be a minimum 18 gauge. Distance limits are determined using the maximum allowable circuit resistance and cable manufacturer's specifications. Restrictions apply when calculating the wire size for the NACs: 1. Minimum supply voltage available is 18.9 V. 2. Minimum required circuit voltage at any NAC is 17 Vdc. 3. Maximum alarm current required for all NACs.
Typical cable pair resistances Wire size
Resistance per 1,000 feet
12 AWG 14 AWG 16 AWG 18 AWG
3.5 Ω 5.2 Ω 8.0 Ω 13.0 Ω
Using Ohm's law, the NAC current requirement, and a voltage drop of 1.9 volts (18.9 - 17), the maximum allowable NAC resistance is determined as follows: Vdrop Rmax = ------Imax
Rmax = Maximum allowable NAC resistance Imax = Maximum NAC current requirement Vdrop = Maximum allowable voltage drop from power supply to NAC
Using this formula, the maximum permissible circuit resistance for a loaded (2.5 A) circuit is 0.76 > as follows: 1.9 V 0.76 Ω = ------2.5 A Using the Load vs. Distance table, the maximum allowable length (D) of any listed wire gauge pair is determined as follows: Rmax D = ------- X 1000 R/1000'PAIR
D = Distance in feet Rmax =Maximum allowable wire resistance R/1000' PAIR = wire resistance per 1000' pair

10 Amp Booster Power Supply
Description The 10 Amp and 6.5 Amp Booster Power Supplies (BPS) are designed to extend a fire alarm ’s signaling capacity. The Booster can be connected to existing Class A or Class B Notification Appliance Circuits (NACs) or activated via Signature Series modules. There are four independent 3.0 Amp NAC circuits supervised in a non-alarm condition. The Booster has a trouble relay that operates on any Booster trouble. The Booster contains a battery charger capable of charging up to two 10 amp hour, 12 V batteries to supply a total of 24 Vdc.

Wiring the Booster Power Supply Wiring placement To avoid noise, keep input wiring isolated from high current output and power limited wiring. Separate high current input/output from low current. Separate power limited from nonpower limited wiring. Wiring within the cabinet should be routed around the cabinet, not across the printed circuit board.

Wiring for internal booster activation of NACs You can turn on the Booster Power Supply using the batteries rather than using one of NAC/AUX outputs. This leaves all four NAC outputs available to power NAC devices. The Signature loop controller issues commands to activate the NACs during fire alarm conditions. In this application, a Signature module receives the command and draws power from batteries wired to the Booster. The Signature module routes the battery power into the Booster's Sense 1 terminal. When the Booster receives power from the Signature module, it activates the NACs. [Battery_booster_activation.CDR]

24 Vdc Notification Appliance Circuit (NAC) specifications
Note: No "T" tapping
permitted.
The NAC cable must be a minimum 18 gauge. Distance limits are determined using the maximum allowable circuit resistance and cable manufacturer's specifications. Restrictions apply when calculating the wire size for the NACs: 1. Minimum supply voltage available is 18.9 V. 2. Minimum required circuit voltage at any NAC is 17 Vdc. 3. Maximum alarm current required for all NACs.
Typical cable pair resistances Wire size
Resistance per 1,000 feet

3.5 Ω 5.2 Ω 8.0 Ω 13.0 Ω
Using Ohm's law, the NAC current requirement, and a voltage drop of 1.9 volts (18.9 - 17), the maximum allowable NAC resistance is determined as follows: Vdrop Rmax = ------Imax
Rmax = Maximum allowable NAC resistance Imax = Maximum NAC current requirement Vdrop = Maximum allowable voltage drop from power supply to NAC
Using this formula, the maximum permissible circuit resistance for a loaded (2.5 A) circuit is 0.76 > as follows: 1.9 V 0.76 Ω = ------2.5 A Using the Load vs. Distance table, the maximum allowable length (D) of any listed wire gauge pair is determined as follows: Rmax D = ------- X 1000 R/1000'PAIR
D = Distance in feet Rmax =Maximum allowable wire resistance R/1000' PAIR = wire resistance per 1000' pair
Using this formula, the maximum length of a loaded (2.5 A) NAC using a pair of 14 AWG wires is: 0.76 146.1' = ------- X 1000 5.2 146 feet is the maximum length of a loaded (2.5 A) NAC branch circuit using a pair of 14 AWG wires.
