SETTING THE CANDELA (SPPS series only)

The candela can be set to 15, 30, 75, 110, 125, 15/75 for SPPS-104-25 and SPPS-104-70 models. The candela can be set to 50, 75, 90, 130, 185, 15/75 for SPPS-104-25H and SPPS-104-70H models. The factory default setting is 15 for SPPS-104-25/70 models, and 50 for SPPS-104-25H/70H models.

Pull out the candela selector from the device.
Re-insert the selector tab into the notch that is labeled with the desired candela setting (when removing or inserting the candela selector, ensure to keep it straight).

Diagram showing the DIP switch configuration with labels for SYNC, NON-SYNC, OFF, and ON.

DIP SWITCH
DIP	OFF	ON
Switch 1 Input*	Synchronized	Regulated 24VDC/ FWR (Non-sync.)

*Note: Use "SYNC” when flash synchronization is required, either through a sync module or built-in synchronization on the control unit. Use "NON-SYNC" when the appliances do not need to be synchronized.

Note: DIP switch 1 default setting is OFF, synchronized.

Note: DIP switch 2 is not used. By default it is OFF.

WIRING

CAUTION

DO NOT LOOP SIGNAL CIRCUIT FIELD WIRES AROUND TERMINALS. ELECTRICAL SUPERVISION REQUIRES WIRE RUN TO BE BROKEN AT EACH END.

Diagram showing correct and incorrect wiring practices for supervision.

FIGURE 4: Figure 4 WIRING TAPS

Diagram illustrating wiring taps for speaker power selection and strobe input power.

Note: This device should be installed as per applicable requirements of the authorities having jurisdiction.

Use the information in this document to determine the total power or current of the devices. The total power or current of the devices must not exceed the output rating of the panel. Refer to the FACP installation guide for the wire size required according to the loop length and devices power usage. For maximum strobe operating current, please refer to Table 5.

FIGURE 5: DEVICE CONNECTION

Diagram showing device connection from a Fire Alarm Control Panel and to the next device, including wiring for speaker and strobe inputs.

*Note: When using with MGC panel or sync module, use MP-300 (3.9K).

Note: Wiring must be in accordance with CSA C22.1, Canadian Electrical Code, Part I, Safety Standard for Electrical Installations section 32 and NFPA 70.

CAUTION

FOR ALL TERMINAL TAPS USED FOR SYSTEM SUPERVISION, DO NOT USE LOOPED WIRE UNDER TERMINALS. BREAK WIRE RUN TO PROVIDE SUPERVISION OF CONNECTIONS.

ATTENTION

NE PAS UTILISER DE FILS EN BOUCLE SOUS LES BORNES. OUVRIR LA LIGNE POUR CONFIRMER LA SUPERVISION DES CONNEXIONS.

MOUNTING

MGC recommends spacing speaker strobe appliances in compliance with CAN/ULC S524 and NFPA72.

(Optional: In case of using a standard 4" square 2 1/8 deep electrical box, attach MP-184 adaptor ring from SPKC-W kit to the unit using 4 snaps.)

Attach the unit to the IB-104 electrical box with the 2 included mounting screws.
Rotate the top cover clockwise to snap it in place.
Secure the top cover with the included securing screw and snap the nameplate over the securing screw.
