Q1 What input voltage is required to operate the Dual/Quad Modem shelf?

Mounted directly on the back of the audible annunciator device, the alarm timer module controls the duration of the audible alarm indication.

Note: The unit is shipped with the jumpers in the default (infinity) position.

The user sets the duration of audible alarm notification by placing a jumper on Z1, Z2, both, or none.
