# Wire an Intercom to a Blue Light Tower

The TS12-N-RB, TS12-N-R2B, TD52, and TD53 can be used as an emergency phone on blue light poles or wall-mounted emergency stations. These poles and wall mounts generally include strobe lights, which should activate during a call.

***

## Installation

This guide includes wiring instructions for a GC31-E cellular gateway and a context camera. In this setup, the GC31-E bridges the LAN, intercom, and context camera. If the LAN fails, the gateway automatically switches to LTE, ensuring continued operation.

### TD53

#### Deployment with GC31-E

{% stepper %}
{% step %}
**Wire the control leads for the blue light strobe into Output 2 (on the back of the intercom).**

{% hint style="warning" %}
Output 2 is automatically configured to trigger during a call when the intercom is configured as an emergency phone. See Configure your Intercom as an Emergency Phone for more information.
{% endhint %}
{% endstep %}

{% step %}
**Wire Ethernet from the intercom Ethernet port to one of the two GC31-E LAN ports.**
{% endstep %}

{% step %}
**Wire Ethernet from the camera into the unused GC31-E LAN ports.**
{% endstep %}

{% step %}
**Wire the WAN port of the GC31-E into the network.**
{% endstep %}
{% endstepper %}

#### Deployment without GC31-E

{% stepper %}
{% step %}
**Wire the control leads for the blue light strobe into Output 2 (on the back of the intercom).**

{% hint style="warning" %}
Output 2 is automatically configured to trigger during a call when the intercom is configured as an emergency phone. See Configure your Intercom as an Emergency Phone for more information.
{% endhint %}
{% endstep %}

{% step %}
**Wire Ethernet from the intercom Ethernet port into the network.**
{% endstep %}

{% step %}
**Wire Ethernet from the camera into the network.**
{% endstep %}
{% endstepper %}

### TS12

#### Deployment with GC31-E

{% stepper %}
{% step %}
**Wire the control leads for the blue light strobe into NO/COM (on the back of the intercom).**

{% hint style="warning" %}
Output is automatically configured to trigger during a call when the intercom is configured as an emergency phone. See [Configure your Intercom as an Emergency Phone](/intercom/configuration/add-and-configure-receivers-in-intercom/configure-an-intercom-as-an-emergency-phone.md) for more information.
{% endhint %}
{% endstep %}

{% step %}
**Wire Ethernet from the intercom Ethernet port to one of the two GC31-E LAN ports.**
{% endstep %}

{% step %}
**Wire Ethernet from the camera into the unused GC31-E LAN ports.**
{% endstep %}

{% step %}
**Wire the WAN port of the GC31-E into the network.**
{% endstep %}
{% endstepper %}

#### Deployment without GC31-E

{% stepper %}
{% step %}
**Wire the control leads for the blue light strobe into output 2 NO/COM (on the back of the intercom).**

{% hint style="warning" %}
NO/COM is automatically configured to trigger during a call when the intercom is configured as an emergency phone. See [Configure your Intercom as an Emergency Phone](/intercom/configuration/add-and-configure-receivers-in-intercom/configure-an-intercom-as-an-emergency-phone.md) for more information.
{% endhint %}
{% endstep %}

{% step %}
**Wire Ethernet from the intercom Ethernet port into the network.**
{% endstep %}

{% step %}
**Wire Ethernet from the camera into the network.**
{% endstep %}
{% endstepper %}

### TD52

#### Deployment with GC31-E

{% stepper %}
{% step %}
**Wire the control leads for the blue light strobe into NO/COM (on the back of the intercom).**

{% hint style="warning" %}
Output 1 is automatically configured to trigger during a call when the intercom is configured as an emergency phone. See Configure your Intercom as an Emergency Phone for more information.
{% endhint %}
{% endstep %}

{% step %}
**Wire Ethernet from the intercom Ethernet port to one of the two GC31-E LAN ports.**
{% endstep %}

{% step %}
**Wire Ethernet from the camera into the unused GC31-E LAN ports.**
{% endstep %}

{% step %}
**Wire the WAN port of the GC31-E into the network.**
{% endstep %}
{% endstepper %}

#### Deployment without GC31-E

{% stepper %}
{% step %}
**Wire the control leads for the blue light strobe into NO/COM (on the back of the intercom).**

{% hint style="warning" %}
Output 1 is automatically configured to trigger during a call when the intercom is configured as an emergency phone. See Configure your Intercom as an Emergency Phone for more information.
{% endhint %}
{% endstep %}

{% step %}
**Wire Ethernet from the intercom Ethernet port into the network.**
{% endstep %}

{% step %}
**Wire Ethernet from the camera into the network.**
{% endstep %}
{% endstepper %}
