3.3.4 Configure Relays, Horn & Strobe Submenu

There is a list of parameters for each relay in the system. The left and right cursor keys can be used to move from one relay, horn or strobe to another. Doing so always goes to the first (summary) display. The up and down keys will scroll through the parameters for the particular relay, horn or strobe.

This display example shows that Relay 1 is configured to operate Normally Off, with a turn on delay and a minimum on time.

Notice that the relay number, 1 in this example, is underlined. This indicates that the digit keys can be used to jump to a particular relay, horn or strobe. The relays are numbers 1, 2 and 3; the horn is number 4 and the strobe is 5.

Figure 3-30 Relay Mode

This display example shows that relay 1 is configured to operate in the Normally Off mode. The relay modes are:

– 1 ALARM

–2 Normally Off (default)

–3 Normally On

Relay mode 1 is a special case. This mode is only available on relay 1 and dedicates the relay to function as an alarm signal to a subsequent alarm or monitoring panel. This mode forces the relay to normally off mode with no turn on delay or minimum on time. See section 3.1.4 for more detail regarding alarms

Fail Safe operation can be implemented by configuring a relay to operate Normally On, and wiring the circuit using the NC (normally closed) contact. In this way, if the control panel looses power the relay will turn on the controlled device if it still has power.
