Chapter 5: Alarm Programming

This chapter explains the alarm programming and monitoring capabilities of the Model 1108, 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

5.1Input Configuration

In preparing the Model 1108 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 2-8, 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 1108 to initialize the eight 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 condition. In the case of a temperature input, an alert condition is recognized when established temperature limits are exceeded.

NOTE

Before starting keyboard commands to configure input normality on the Model 1108, it is very impor- tant to check that the sensors you have wired to the unit are set in their normal, non-alarm positions.
