Aiphone IS-HTR INSTALLATION Flush mount unit, Specifications, Wire/ Distance Reference table

INSTALLATION: Flush mount unit

1.Ensure that the conformal side (orange) of IS-HTR is facing the door station. Route all door station wiring through the wiring provision opening on the IS-HTR.

2.Connect the door station wiring to the unit and connect the IS-HTR wires (flying leads) to a power source, 24V AC/DC.

3.Remove the 4 nuts and washers holding the plastic chassis to the metal front panel. Place the IS-HTR as shown and reuse the nuts and washers to secure the IS-HTR to the door station. Note: Ensure that there are no gaps between the door station and heater when installed.

4.Mount the door station and heater together to the desired backbox using the supplied hardware.

1. 2. 3.

Note: When using the IS-HTR with IS series emergency stations, the external relay board wires should not be run through the IS-HTR.

Wire/ Distance Reference table:
	10AWG	11AWG	14AWG	16AWG	18AWG	22AWG
24V (25W)	1150’	725’	455’	285’	180’	70’

Special Precautions:

Installation and servicing should only be done by qualified service personnel and conform to all local building and electrical codes.

When a single power source is used for both the sub station and heater module, the sub station power consumption must be taken into consideration when determining the wire gauge.

Application Suggestion:

Though not a requirement, it is recommended that a site-wide temperature controller be used in conjunction with the main power source(s) for the heater(s) utilized. Ideally this would prevent unnecessary heater activation during the summer months where heater operation is not necessary (but temperatures are below the thermostat set point of 15ºC). Additionally, the reduced operation of the thermostat would also increase the service lifespan of the heater module itself.
