Audible/visible (A/V) notification appliances with
efficient electronic horn and high output xenon
strobe, available for wall or ceiling mount
- Operation is compatible with ADA requirements (refer to important installation information on page 3)
- Rugged, high impact, flame retardant thermoplastic housings are available in red or white with clear lens
Operates over a two-wire SmartSync circuit to provide:
- Horns that are controlled separately from strobes on the same two-wire circuit
- “On-until-silenced” and “on-until-reset” operation on the same two-wire pair
- SmartSync horn activation of Temporal pattern, March Time pattern (at 60 BPM), or on continuously
- Strobe appliances on the same circuit operating at a synchronized 1 Hz flash rate
- Class B operation requires connection to a compatible SmartSync NAC or to SmartSync Control Module (SCM) 4905-9938
- Class A operation when connected to the 4905-9938 SCM or with 4100U series fire alarm control panel NACs
Wall mount A/Vs features:
- Wiring terminals are accessible from the front of the housing providing easy access for installation, inspection, and testing
- Covers are available separately to convert housing color
- Available UL listed sound damper for locations requiring attenuation of 5 to 6 dBA (stairwells, small rooms, highly reverberant areas, etc.)
Optional adapters and wire guards:
- Wall mount A/V adapters are available to cover surface mounted electrical boxes and to adapt to Simplex ® 2975-9145 boxes
- UL listed red wire guards are available for wall or ceiling mount A/Vs
Visible notification appliance (strobe):
- 24 VDC xenon strobe; intensity is selectable as 15, 30, 75, or 110 candela with visible selection jumper secured behind strobe housing
- UL listed to Standard 1971
- Regulated circuit design ensures consistent flash output and provides controlled inrush current
Audible notification appliance (horn):
- Low current, 24 VDC electronic horn with harmonically rich sound output suitable for either steady or coded operation (Temporal or 60 BPM March Time pattern)
- UL listed to Standard 464
Description
Multi-Candela TrueAlert A/Vs with horn and
synchronized strobe provide convenient installation
to standard electrical boxes. The enclosure designs are
both impact and vandal resistant and provide a convenient
strobe intensity selection. Since each model can be
selected for strobe intensity output, on-site model
inventory is minimized and changes encountered during
construction can be easily accommodated.
Wall mount A/V housings are a one-piece assembly
(including lens) that mounts to a single or double gang, or
4” square standard electrical box. The cover can be
quickly removed (a tool is required) and covers are
available separately for color conversion.
Ceiling mount A/Vs install using standard 4” electric
Strobe Intensity Selection
During installation, a selection plug at the back of the
housing determines the desired strobe intensity. An
attached flag with black letters on a highly visible yellow
background allows the selected intensity to be seen at the
side of the strobe lens.
Strobe Application Selection
Proper selection of visible notification is dependent on
occupancy, location, local codes, and proper applications
of: the National Fire Alarm Code (NFPA 72), ANSI
A117.1; the appropriate model building code: BOCA,
ICBO, or SBCCI; and the application guidelines of the
Americans with Disabilities Act (ADA).
Synchronized Strobes
Multiple Strobes. When multiple strobes and their
reflections can be seen from one location, synchronized
flashes reduce the probability of photo-sensitive reactions
as well as the annoyance and possible distraction of
random flashing. The multi-candela strobes of these A/Vs
are synchronized by the controlling SmartSync operation
NAC.
SmartSync Two-Wire Control
SmartSync operation mode allows a two-wire circuit to
provide the ability to activate both the horn and strobe on
the same NAC and then allow the horn to be silenced
while the strobe remains flashing. The horn operates as
“on-until-silenced” while the strobe operation is
“on-until-reset.”
