a. If using the wall tamper function for increased security, mount 
the housing back plate per Figure 3, ensuring the tamper switch 
is depressed.

 Figure 3  EN1240-60 mounting back plate

b. If not using the wall tamper, mount the housing back plate 
using all appropriate hardware.

The following should be considered when mounting the EN1240-60:

• The activity sensor should be mounted such that the expected 

intrusion motion is perpendicular to the protection zones

• The activity sensor may not detect motion behind obstructions, 

including blinds, curtains, and drapes

• The activity sensor should be mounted on a solid, vibration-free 

mounting surface

• Fans and blowers can cause false alarms.
• The following may cause false alarms:

-  Fans
-  Blowers
-  Drafts
-  Windows
-  Heat and cooling sources
-  Sunlight
-  Animals

The optional ceiling and wall mount brackets are available separately from 
Inovonics, part number ACC665.

Note: Applications that require the back tamper cannot use the ceiling or 
wall mount bracket.

 Figure 4  Ceiling and wall mount brackets
To mount a ceiling or wall bracket:
1. Remove the pcb board.

2. Attach the housing to the bracket.

 Figure 5  Remove the pcb board and attach the housing to the bracket
3. Replace the pcb board.

Caution: The EN1240-60 should be tested after registration, and at least 
once a year thereafter, to ensure operation. To test the EN1240-60, activate 
each of the conditions and ensure an appropriate response.

The walk test is performed to ensure motion is sensed and an RF 
transmission results. To perform a walk test:
1. Swipe a magnet past the reed switch. The five minute walk test will 

begin; every time motion is sensed, the LED will light.

Note: During walk test, the EN1240-60 will not transmit alarms when 
motion is detected; only the LED will light.

2. Walk in front of the activity sensor to test the sensor. 
3. After five minutes the walk test will automatically end.

The EN1240-60 transmitter signals an alarm condition when motion is 
detected by the sensor.
