INSTALLING THE AUDIO ALARM
The installer MUST connect the included audio alarm per these instructions. Installing the audio alarm is
REQUIRED for UL325 compliance.
The audio alarm (siren) included in the kit must be connected to the 1050 control board to provide an
audible alarm to indicate a hard shutdown of the system, which is triggered by two consecutive entrapment
events. It is a piezoelectric device that can produce a minimum of 100 dB @ 1 foot from enclosure per UL
code of continuous sound and is powered by 3-12 VDC. Install as follows:
1. The alarm has short leads but may be located inside the
box without wiring in additional cable.
NOTE: If using additional cable length for installation of
alarm external to the control box, maximum wire/cable
length is 1000 feet (308.4m).
2. Locate the alarm output connector per IMAGE 22-1.
3. Connect red wire to Pin 14 (Alarm), and black wire to Pin 15
(GND).
4. In the event of a hard shutdown, be sure to determine
the problem before resetting the shutdown (pressing the
RESET Button on the control board).
