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.

Figure 3-29 Relay Summary 

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: 

 

ALARM 

 

Normally Off (default) 

 

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. 

3.3.4.3

 

Relay Turn On Delay

Figure 3-31 Turn On Delay 

The default turn on delay is one minute and the maximum allowed value is fifteen minutes. The value is entered 
in two groups, 2 digits for the minutes and then 2 digits for the seconds. A leading zero must be entered for each 
group if applicable.
