The ATRIUM 2-Door Controller supports the connection of one or several bells or sirens in parallel. The high
current output allows to drive bell(s)/siren(s) in parallel for up to 40 watts total. The Bell control circuitry gives
the following indications.
• Indication of bell/siren Output activation using LED.
• Complete and Real-Time Bell/Siren proper operation and failure monitoring.
• Bell Short / Presence detection even when Bell isn’t activated along with
common Automatic shutdown of bell output on over current.
• Programmable Automatic restore: either on next deactivation/activation cycle or
after a programmable reset delay.
Connect the bell(s) and/or siren(s) on the “+” and “-” terminal. There are two sets of “+” and “-” terminals on
the PCB that are wired in parallel allowing to connect two or several bells and/or sirens in parallel.
To allow the monitoring of the bell/siren, a 1Kohms resistor is required in parallel if the bell/siren has
a high impedance.
See “Recommended Wiring” section for more information on wiring type, size, and maximum length.
