Installation and Use Manual

Description

These 10-step plus “OFF” speaker attenuators allow the volume of a network of 25V or 70V speakers to be controlled from a remote location. The ATP10 attenuator can handle speaker loads of up to 10W (max.) and the ATP35 attenuator can handle speaker loads of up to 35W (max.). The ATP10 fits into a single gang electrical box and the ATP35 attenuator fits into a double gang electrical box.

Each unit includes a bypass function for overriding the volume control knob setting when activated by 9V to 30V DC. Applying 9V to 30V DC between pins labeled D+ and D- bypasses the volume control function and provides full volume audio to the speakers.

Bypass Connection Examples

In the example below, the AUX contacts of the Universal Telephone Interface (UTI1) are programmed to close when the UTI1ʼs Override (Emergency) input becomes active. The AUX contacts switch 24V from the UTI1 power supply terminals to the Bypass input of the ATP10 or ATP35, allowing a full volume page to be heard regardless of the volume setting of the attenuator. See front page for amplifier and speaker wiring.

The bypass terminals override the volume control setting whenever 9V to 30V DC (at 22 mA) is applied to the D+ and D- terminals. See front page for amplifier and speaker connections.

In this configuration the Bypass feature activates when the zone is being paged, but allows volume control when the zone is inactive and background music is playing. See PCM Manual for amplifier connections and front page for speaker connections.

* Use a 12V regulated power

supply. Non-regulated supplies may provide significantly more than 12V when not fully loaded. Greater than 12V supply will cause relay driver to conduct even when not active. A 9V unregulated power supply will

typically work appropriately.
