Chapter 2: Installing the Plus Touch
20
Connecting an alarm system
You can connect an alarm system to the Plus Touch’ alarm terminal. An alarm system can be a siren,
alarm panel, or auto-dialer. Read your system’s installation guide for installation instructions and
information about the type of system:
normally open
or
normally closed
. Below are the descriptions
for the alarm terminal.
COMM
: common connection
N/O
:
normally open; closes during alarm conditions
N/C
:
normally closed; opens during alarm conditions
For the alarm system to sound (or dial out) during an alarm condition, you must enable the alarms.
For more information, read
Programming alarms
The ratings of the siren or alarm system must not exceed the ratings of the Plus
Touch’ alarm relay.
Alarm relay ratings
:
0.4 A at 125 VAC; 2 A at 30 VDC, resistive load
0.2 A at 125 VAC; 1 A at 30 VDC, inductive load
To connect a normally open alarm system
If you are connecting the alarm system to a network of Plus
Touch controls and your system uses a
normally open connection
(closes on alarm), connect the system as shown in the normally
open diagram.
Join all the COMM connections together and all the N/O
connections together. The Plus Touch alarm relays must be in
parallel with each other so any Plus Touch can trigger the alarm
system when an alarm condition occurs.
To connect a normally closed alarm system
If you are connecting the alarm system to a network of Plus
Touch controls and your system uses a
normally closed connection
(opens on alarm), connect the system as shown in the normally
closed diagram.
Join the alarm relays in a continuous loop. The Plus Touch alarm
relays must be in series with each other so any Plus Touch can
trigger the alarm system when an alarm condition occurs.
