    Specifications and wiring diagram for the SECO-LARM E-37EV Alarm Pager System, a wireless paging system for burglar alarm panels, vehicle alarms, and other trigger inputs.

    Overview

    The E-37EV Alarm Pager System monitors up to three zones per premises or vehicle, plus manual paging, and can connect to nearly any type of burglar alarm control panel, vehicle alarm, or communications panel. When a monitored input triggers, the belt-clip receiver alerts the wearer with distinct color LEDs, audible beeps, or vibration — useful anywhere a technician or business owner needs to be paged when an alarm zone activates without a hardwired connection.

    Features

    • Monitors up to three zones per premises/vehicle, plus manual paging — one positive and two negative instant trigger inputs.
    • Range up to one half mile (4W output); actual range varies by environment, installation, and antenna.
    • Over two million possible coding combinations; code-learning receiver learns up to three transmitters.
    • Color LEDs (Green, Orange, or Red) on the receiver indicate which zone was triggered.
    • Audible or vibrating page indicator; stores the last six pages for easy recall.
    • EEPROM memory stores codes for up to one year without power.
    • Unattended page indicator and low battery indicator.
    • Receiver uses two AAA batteries (not included); extra vibrating receiver available (E-37RV).
    • Connects to a CB antenna, car AM radio antenna (adapter cable included), or external antenna (E-37ANT). Antenna required, not included.

    Available Accessories

    • E-37RV — spare receiver for the E-37EV, with built-in audible or vibrating function for silent paging.
    • E-37ANT — antenna that plugs into the back of the transmitter for use where no existing AM/CB antenna is available, or where an existing antenna might be vandalized.

    Negative Trigger Input 1 Zone LED flashes Red Beeps/vibrates in groups of 9 for 1 minute
    Negative Trigger Input 2 Zone LED flashes Orange Beeps/vibrates in groups of 9 for 1 minute
    Manual Page Zone LED flashes Green Beeps/vibrates in 3 groups of 3 for 1 minute
    Power ON Zone LED not lit Beeps/vibrates in 3 groups of 3 for 1 minute
    Low Battery — Beep/vibrate twice every 60 seconds, or when switch is pushed
    Memory Full — Three continuous beeps/vibrates at end of all signals
    Unattended Page — Beep/vibrate once every 30 seconds until acknowledged

    Basic Wiring

    The transmitter's Antenna Selection Switch (A/B) routes to the Antenna Jack or Radio Jack (to radio and/or power antenna, if needed). Wire connections: Red = constant +12V to fuse box; Black = ground; Purple = positive trigger; Blue = second negative trigger; Green = first negative trigger. A Manual Page button is also wired in.
