EN1252 Long Range Dual Input
Universal Transmitter
Installation Instructions
1 Overview
The EN1252 long range dual input universal transmitter provides
five times the power of standard Inovonics universal transmitters.
To support the increased power, the EN1252 can operate using
an external power source or the internal battery. The unit is
designed for use with any standard contact or sensor that
provides a contact closure – normally open or closed – and
includes connections for two alarm inputs as well as tamper and
reset.
Note: The EN1252 requires use of a serial receiver or network
coordinator, as well as an application designed to support
advanced functionality.

2 Installation and Startup
2.1 Installation Notes
• These products are designed to be maintained by
professional security technicians
• Products are tested for indoor use
• All products should be manually tested weekly
2.2 Install the Battery
1. Pry the top lip of the mounting bracket up, and lift the bracket
off of the transmitter.
2. Use your thumb to depress the housing release tab on the
bottom of the transmitter; separate the housing.
3. Install the battery.
2.3 Connect Input Wiring
The transmitter has a three-terminal contact block that can
connect inputs from one or two external contact loops. The
middle terminal is a ground, which is shared by both contact
loops. Input one can be configured for either a normally open or
a normally closed contact loop using the NO/NC selection pins;
input two is always normally closed.
4. Connect cabling to input one and/or input two, as desired.
• The distance from the external contact to the EN1252 must
not exceed 10 feet (3 meters).
2.4 Select Input Type
The N/O-N/C selection pins allow the choice of a normally open
or normally closed state for the contact circuit wired to the input
one terminal. The terminal is shipped set for normally closed,
with no selection jumper on the N/O selections pins. If you need
the input one terminal set for normally closed, no action is
needed; skip to 2.5, “Enable/Disable Housing Tamper”.
5. Place a selection jumper on the selection pins to select
normally open.
2.5 Enable/Disable Housing Tamper
The tamper disable selection pins allow the housing tamper to be
disabled. If you do not wish to disable the tamper, no action is
needed; skip to 2.6, “Register the EN1252”. If you wish to disable
the housing tamper:
6. Place a selection jumper on the tamper disable selection pins
to disable the housing tamper.
7. Press the reset button to complete configuration.
Caution: When pressing the reset button, make sure you don’t
also touch any selection pins. Touching selection pins while
pressing the reset button can inadvertently set the EN1252 to an
undesired configuration.
2.6 Register the EN1252
Transmitters must be registered with the system in order to be
monitored and supervised. When supervised, the transmitter will
send a check-in message to the receiver. Transmitters will send
a check-in message every three minutes. Each transmitter has a
unique factory-programmed identification number.
Note: Refer to the receiver installation instructions for details
about registering a transmitter.
8. When prompted by the receiver to reset transmitter, press
the reset button.
9. Replace the cover.
Caution: The EN1252 should be tested after registration to
ensure operation. To test the EN1252, activate each of the
conditions and ensure an appropriate response.
2.7 Mount the EN1252
10. Mount the bracket on the wall with the screws provided so
that the catch is on the bottom.
11. Clip the transmitter onto the bracket. Hook the bottom catch
first, then press the top into place.
