Flash Rate: | 1 flash per second |
Operating Temperature: | 32° F to 120° F (0° C to 49° C) |
Selectable Light Outputs: | All candelas are selectable via a manual slide switch. |
12/24 Volt Applications: | 15 or 15/75 candela |
24 Volt Application: | 30, 75, 110 candela |
| 15/75 is listed at 15 candela per UL 1971 but will provide 75 candela on axis |
| (straight ahead). 15, 30, 75, or 110 are rated for that candela. |
Sound Output: | Sound output levels are established at Underwriters Laboratories in their reverber- |
| ant room. Always use the sound output specified as UL Reverberant Room when |
| comparing products. |
Listings: | UL S5512 (Strobe); UL S4011 (Combo) |
Note for Strobes: | Do not exceed: 1) |
| strobe lights when connecting the MDL Sync module with a maximum line im- |
| pedance of 4 ohms per loop and; 3) maximum line impedance as required by the |
| fire alarm control manufacturer. |
The models S1224MC, S1224MCW, S1224MCSP, S1224MCSPW, S1224MCP, S1224MCPW, P1224MC, P1224MCW, P1224MCSP, P1224MCSPW, P1224MCP, and P1224MCPW incorporate a patented voltage booster design that has a more consistent flash bulb voltage over the range of candela selections. The benefit to the customer is a high quality strobe device.
General Description
The SpectrAlert series notification appliances are designed to meet the requirements of most agencies governing these devices, including: NFPA, ADA, The National Fire Alarm Code, UL, ULC, FM, CSFM, MEA. Also, check with your local Authority Having Jurisdiction for other codes or standards that may apply.
The SpectrAlert series can be installed in systems using 12- or 24- volt panels having DC or

Fire Alarm System Considerations
Temporal and
The American National Standards Institute and the National Fire Alarm Code require that all horns used for building evacuation in-
stalled after July 1, 1996, must produce Temporal Coded Signals.
Signals other than those used for evacuation purposes do not have to produce the Temporal Coded Signal. Temporal coding is accom- plished by interrupting a steady sound in the following manner:
1/2 Sec. | 1/2 Sec. | 1/2 Sec. | 1/2 Sec. | 1/2 Sec. | 11/2 Sec. | Repeats |
On | Off | On | Off | On | Off |

Power Supply Considerations
Panels typically supply DC filtered voltage or FWR
