The Edwards 965-7A-4RW is a 4-inch round white 70 Vrms ceiling speaker-strobe with a 15/75 cd dual-rated strobe, designed for fire-alarm voice-communication systems. Specifically, it combines an 8-ohm cone speaker with a 24 Vdc xenon strobe in a single appliance. Furthermore, it is part of the Edwards EST 965 Series Enhanced Integrity product line.
First, the speaker cone is 4-inch (102 mm) mylar with sealed-back construction. Then the 24 Vdc strobe synchronizes at one flash per second. As a result, this device delivers integrated emergency voice and visible notification — and meets UL 1971 for both wall and ceiling mounting.
Verified Strobe Specifications
- UL 1971 rated output: 15 cd (wall or ceiling mount)
- UL 1638 rated output: 15/75 cd (75 cd on-axis per UL 1638 / ADA)
- ULC S526 rated output: 15 cd
- Strobe input voltage: 16 to 33 Vdc continuous (must be constant, not pulsed)
- Flash rate: 1 flash per second (synchronized)
- Standard lens marking: LKC-1 “FIRE” red letters, ceiling orientation
However, for wall-orientation “FIRE” lettering or alternative languages, see the optional LKW Series lens marking kits. Therefore, change the lens marking by snapping on the appropriate kit at install.
Verified Speaker Specifications
- Operating voltage: 70 Vrms audio circuit (965 Series)
- Frequency response: 400 to 4,000 Hz
- Cone: 4-inch (102 mm) mylar, sealed-back, 8 W rated, 8-ohm voice coil
- Wattage taps measured at 10 ft per UL 1480: 1/4W = 79, 1W = 82, 2W = 85, 4W = 88 dBA
- DC blocking capacitor included for electrical supervision of the audio circuit
Operating Current (Strobe)
Specifically, the strobe operating current for the 15/75 cd variant:
- Typical at 24 Vdc: 90 mA
- UL rated at 16 Vdc: 150 mA
- UL rated at 16 Vfwr: 210 mA
Therefore, use the 16 Vdc value for battery AH calculations and the 16 Vfwr value for unfiltered-power-supply calculations.
Synchronization
Furthermore, the 965-7A-4RW exceeds UL 1971 sync requirements (within 10 ms over a two-hour period) when used with an external sync source. Specifically, compatible sync modules include:
- G1M-RM (Genesis Signal Master Remote Mount)
- SIGA-CC1S (Standard Mount Synchronization Output Module)
- SIGA-MCC1S (UIO Mount Synchronization Output Module)
- BPS6A / BPS10A (Booster Power Supplies)
Operating Environment and Mounting
Specifically, the 965-7A-4RW is rated for indoor use only:
- Temperature: 32 to 120°F (0 to 49°C)
- Humidity: 85% relative humidity at 86°F (30°C)
Also, the recommended flush back box is the Edwards 960A-4RF. Alternatively, mount to a standard 4-inch square electrical box, 2-1/8 inches (54 mm) deep, with a 1-1/2 inch extension ring. As a result, baffle diameter is 7.35 in (187 mm), depth behind baffle is 3.625 in (92 mm), and ship weight is approximately 3.3 lb (1.5 kg).
Verified Listings
- UL 1971 (visible notification for the hearing impaired — wall OR ceiling at 15 cd)
- UL 1638 (visible signaling appliance — 75 cd on-axis)
- UL 1480 (speakers for fire-protective signaling systems)
- ULC S526, ULC S541
- CE Compliant, FM, CSFM, MEA
- ADA compliant per Code of Federal Regulation Chapter 28 Part 36 Final Rule
What This Part Is
However, the -7A position code denotes the 15/75 cd dual-rated strobe. Specifically, it provides 15 cd UL 1971 (the standard fire-alarm wall/ceiling rating) plus 75 cd UL 1638 on-axis (the ADA visible-signal rating). Therefore, the -7A is the most common 70 V ceiling speaker-strobe spec.
Also, the 965 Series targets 70 Vrms audio. As a result, for 25 Vrms audio, use the 964-7A-4RW instead.
