Chapter 5: Alarm Programming
This chapter explains the alarm programming and monitoring
capabilities of the Model 1104, with specific instructions for
the following features:
• Configure inputs as dry contact or temperature
• Enable/disable inputs
• Program alarm Recognition Time for each input
• Program high and low temperature limits
• Disable alarm response to high or low temperature
• Program temperature in Fahrenheit or Celsius scale
• Calibrate temperature
• Obtain current temperature
• Program AC power-failure Recognition Time
• Enable/disable AC power monitoring
• Program sound level sensitivity
• Program high sound Recognition Time
• Disable alarm response to high sound
• Use Exit Delay via Status Report
5.1 Input Configuration
In preparing the Model 1104 to sense an alert condition, the
inputs must be configured as dry contact (either open or closed)
or as temperature inputs. The default setting for input 1 is
temperature; for inputs 2-4, the default is dry contact and open.
To configure input normality, sensors are first wired to the
terminal strip at the back of the unit. (Refer to Chapter 2,
Section 2.9–2.12, for an explanation on wiring inputs.)
The configuration process directs the Model 1104 to initialize
the 4 inputs and establish normal settings. Any change in the
status of an input (for example, from a normally open contact
to a suddenly closed contact) is recognized as an alert condi-
tion. In the case of a temperature input, an alert condition is
recognized when established temperature limits are exceeded.
