2 Bosch Voice Evacuation Systems
Use the EVAX25EM, EVAX50EM, or EVAX100EM expander panel when a 25 W, 50 W, or 100 W audio expander is needed with its own enclosure. Use the EVAX150EM and EVAX200EM for expansion when greater power is required in the larger enclosure configuration. The EM models have all the features of the E models except they are without a paging microphone.
Optional Expander Modules
The expander modules (EVX- models) can increase the capacity of any Bosch voice evacuation system or expander panel. They do not have paging microphones and are intended for installation in UL Listed enclosures (not supplied). Features of these modules:
•Audio amplifier
•Power regulator and battery charger
•Tone generator
Optional Zone Splitters
The EVX‑4Z and EVX‑2ZA zone splitters allow the supervised output of any Bosch audio amplifier to supervise multiple zones. Features of these zone splitters:
•Manual selection of any or all voice evacuation zones for emergency paging
•Automatic selection of voice evacuation zones by connecting normally‑open contacts from the FACP or other auxiliary control system
•Annunciation of either active or faulted zone status by individual LEDs
•Compatibility with jumper‑selectable 25 V and 70 V amplifier outputs
The EVX‑4Z has four Class B zones. The EVX‑2ZA has two Class A zones.
Functions
Digital Message Repeater
Each of the Bosch voice evacuation systems (EVAX25, EVAX50, EVAX100, EVAX150, and EVAX200) includes a digital message repeater (DMR). The systems come with the following standard 15‑second message programmed:
"Attention, please. There has been a report of an emergency. Proceed calmly to the nearest exit and leave the building immediately. Do not use the elevators; use stairwells where necessary. All handicapped occupants shall use the building evacuation plan."
The voice evacuation message is broadcast until the FACP resets or until emergency personnel interrupt the broadcast with a manual page. When the FACP resets, the voice evacuation system automatically returns to normal operating condition.
The closure of a contact from either the FACP or from any normally‑open contact device can cause the broadcast of a chime tone followed by the message "All clear."
Optional primary and secondary messages are available. For further information, refer to the Bosch Voice Evacuation
System's Optional Messages Technical Service Note (P/
N: F01U500869).
Remote Paging Microphones
Remote paging microphones (up to five per EVX‑SC supervisory card) are supported through a supervised circuit. Remote microphones may be mounted up to 5000 ft (1.5 km) away from the EVAX voice evacuation panel. An ideal use for a remote microphone is when the FACP and voice evacuation system panels are in an electrical room and you need a microphone in the lobby.
System Settings
Control system operation by DIP switch settings:
•Configure three DIP switches to determine alert tones of Temporal Slow Whoop (default), Hi Lo, Horn, Bell, or 1 kHz.
•Turn the Diagnostic Mode on or off (default).
•Set the AC Power Failure Report for no delay (default) or for a six‑hour delay.
•Indicate if batteries are connected to the system. The default setting is batteries are connected.
•Indicate if a microphone is connected to the system. The default setting is a microphone is connected.
•Set the initial delay before a message starts for no delay, 4‑second delay, 8‑second delay (default),
12‑second delay, 16‑second delay, 20‑second delay,
24‑second delay, or 28‑second delay. The chosen tone sounds during the delay.
•Set the delay between repeats of the message for a 4‑second delay,
•Indicate if the message plays or not. Message on is the default.
•Set the number of times the message plays to one play, two plays, three plays (default), or continuous play.
