ABOUT THIS MANUAL
This manual is included as a quick reference for installation. For further
information on the use of this device with a FACP, please refer to the panel’s
manual.
Note: This manual should be left with the owner/operator of this
equipment.
SPEAKER/SPEAKER STROBE DESCRIPTION
The SPPS-204 speaker-strobe is designed to meet UL1480/ULC S541 requirements for speakers and UL1638 /ULC S526, UL 1638A/CSA C22.2 No.205 requirements for visual notification appliances. The SPP-204 speaker is designed to meet UL1480/ULC S541 requirements for speakers.
*Note: For FWR signaling use an MGC panel.
SETTING THE CANDELA (SPPS series only)
The candela can be set to 15, 30, 75, 110, 185, 15/75 for SPPS-204-25 and
SPPS-204-70 models.
Note: 185cd setting is for General Signaling only.
The factory default setting is 15 for SPPS-204-25/70.
- 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).
Note: Select the candela setting prior to installing the device in the mounting plate.
SETTING THE DIP SWITCHES
Table 2: 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.
- DIP switch 1 default setting is OFF, synchronized.
- DIP switch 2 is not used. By default it is OFF.
WIRING
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.
*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.
CAUTION
DO NOT LOOP SIGNAL CIRCUIT FIELD WIRES AROUND TERMINALS. ELECTRICAL
SUPERVISION REQUIRES WIRE RUN TO BE BROKEN AT EACH END.
Note: When using with MGC panel or sync module, use MP-300 (3.9K).
Correct: Wire run is broken
Wrong: Wire is looped around terminal
MOUNTING
MGC recommends spacing speaker strobe appliances in compliance with CAN/ULC S524 and NFPA72.
- Attach the mounting plate to the electrical box with the 2 included mounting screws.
- Insert the device to the mounting plate with 2 screws.
- Attach the top cover with the included securing screw and snap the nameplate over the securing screw.
Note: Select the candela setting prior to installing the device in the mounting plate.
